Shifting with Automatic Transmission from G2 Owner's Manual

(D4) - For normal Driving Conditions

(D3) - This position is similar to D4, except only the first 3 gears are selected. Use D3 when towing a trailer in hilly terrain, or to provide engine braking when going down a steep high. D3 can also keep the transimission from cycling between 3rd and 4th gears in stop and go driving.

(2) - This position locks the transmission in second gear. It does not downshift to first gear when you come to a stop. Second gives you more power when climbing, and increased engine braking when going down steep hill. Use 2nd gear when starting out on a slippery surface or deep snow. It will reduce wheel spin.

(1) - This position locks the transmission in 1st gear.

Other notes:
- For faster acceleration in both D3 and D4, you can get the transimission to downshift by pushing the accelerator to the floor. The transimission will shift down one or two gears depending on your speed.

- When you move the shift lever to a lower gear, the transmission downshifts only if the engine's redline will not be exceeded in the lower gear.

- By upshifting and downshifting through 1, 2, D3, D4, you can operate this transmission much like a manual transmission without a clutch pedal.


Brakes (stock)
Type I – Dual-diagonal, power-assisted, 4 wheel disc brakes.
Front – 11.0” diameter
Rear – 11.0” diameter
ABS System – 4 wheel speed sensors and electronic/hydraulic control unit
Type II – Same as above, rotors 5mm thicker for better braking, dual piston front calipers.

Trim Levels
*In order from lowest to top of the line*
Sedan Trim Levels
Base | L | SE | LS | GS

Base Model:

In 1991-1993 the Base model Acura Legend Sedan, as base level was only available on the sedan, was a bare minimum Acura Legend. In a sense, the Base model was the stripped down racer (joke)

Standard Features:
Driver Side power seating, Cloth seat coverings, Speed Sensitive Power Steering, 3.2litre Single Over Head Cam 200 hp (210 lbs/ft) V6, 5 speed Manual Transmission, 4 speaker audio system with AM/FM Cassette player with automated Power antenna, Unpainted body protecting trim panels.

• Separated Rear headrests

L Model:

In 1991-1993 the L model was the second step up in the Legend line up of luxury. In 1994 the Base model was dropped and the L became the new Base Model. In 1991-1993 the option list was smaller than in 1994.

Standard Features:
Driver Side power seating, Cloth seat coverings, Speed Sensitive Power Steering, 3.2litre Single Over Head Cam 200 hp (210 lbsft) V6, 5 speed Manual Transmission, 4 speaker audio system with AM/FM Cassette player with automated Power antenna, Unpainted body protecting trim panels, Floor mats, Moon roof, Body colored mirrors and door handles, bronze tinted windows

• Heated seats
• Passenger side Supplemental Restraint System (air bag)
• Acura Cell Phone

In 1993 the airbag became standard across the board.

Also in 1993 the list shortened. Body colored trim panels and were removed as those were standard. But an option for premium sound was offered in the L model in 1994. This was not like the Bose Ext. Amp setup in the LS though. Also in 1994 the Speaker system went from 4 to 6 drivers.

SE model:

In the final years of production the Legend started showing its age in the segment. Competition started catching up to the Ahead-of-its-time Legend. In 1995 in a last-ditch attempt to rid of the rest of the KA7 chassis, Acura devised a final year “Special Edition”, hence the name SE. Not Sport, or Sacred, but Special Edition. This model was to the most out of the sell out of the chassis that Acura could before they brought out the RL. As a result it was only produced for the Final production year 1995.

The SE in itself is not much more than an L Model, but there were some things added that made it more than an L but not as much as an LS. And not many options available.

Standard Features:
Driver Side power seating, Leather seat coverings, Speed Sensitive Power Steering, 3.2litre Single Over Head Cam 200 hp (210 lbsft) V6, 4 speed Automatic Transmission, 6 speaker audio system with AM/FM Cassette player with automated Power antenna, Painted body protecting trim panels, Special Edition Floor mats, Moon roof, Body colored mirrors and door handles, bronze tinted windows. Faux Wood Trim, Two Tone Paint job

Optional Features:
• Acura Cell Phone
• Trunk Net
• Differing Color options for the SE used colors from the Legend’s Palette already.
• Top Color First:
o Pearl White/Desert Mist
o Geneva Green/Canterbury Green
o Granada Black/Seattle Silver



LS Model:

The LS model was the top of the line 1991-1993. The LS model came loaded down and had a short option list. It is probably the most luxurious of all Legend levels. In 1994 some changes were made.

Standard Features:
Driver Side power seating, LEATHER seat coverings, Speed Sensitive Power Steering, 3.2litre Single Over Head Cam 200 hp (210 lbsft) V6, 5 speed Manual Transmission, 4 speaker audio system with AM/FM Cassette player with automated Power antenna, body colored body protecting trim panels, Floor mats, Moon roof, Body colored mirrors and door handles. Bronze tinted windows, Light and Temperature Sensitive Automatic Climate Control, Heated seats, heated mirrors, Height adjustable seatbelts, Passenger Side Supplemental Restraint System (Airbag)

Optional Features:

• Trunk Net
• Acura Cell Phone
• 6 Disc CD changer

In 1994 the LS lost the 5 speed manual transmission availability



GS Model:

In 1994, the LS was displaced, by name, as the Top of the line model. The GS for all intents and purposes was an LS model with a different drive train, braking system, and suspension. It was truly the Driver’s Car, of the Legend family and Today still is one of the most sought after models on the planet and was the Swan Song of the Acura Legend. Also it was the first Acura Sedan and one of the first road cars to ever house a 6 speed manual transmission.


Standard Features:
Driver Side power seating, LEATHER seat coverings, Speed Sensitive Power Steering, 3.2litre Single Over Head Cam 230 hp (206 lbsft) V6, 6 speed Manual Transmission, 6 speaker audio system with AM/FM Cassette player with automated Power antenna, body colored body protecting trim panels, Floor mats, Moon roof, Body colored mirrors and door handles.

Coupe Trim Levels
L | LS

When the 2nd Generation Acura Legend was introduced the sedan came out immediately the coupe followed suit in mid-model year. When it was introduced however it was only introduced with 2 trim levels, L and LS. From the beginning the coupe was only supposed to be similar to the sedan in presence, hence the almost zero compatibility in exterior and interior panels. The coupe was a totally different car than the sedan; the only thing shared was the engine and chassis, to generalize it.

L Model Coupe:

In 1991 and 1992, the lowest level of the Coupe was L. Similar to the sedan, the L offered a good bit of options on this level. But it was pretty much loaded to the hilt from the start.

Standard Features:
Driver Side power seating, fabric seat coverings, Speed Sensitive Power Steering, 3.2litre Single Over Head Cam 200 hp (210 lbsft) V6, 5 speed Manual Transmission, 4 speaker audio system with AM/FM Cassette player with automated Power antenna, Unpainted body protecting trim panels, Floor mats, Moon roof, Body colored mirrors and door handles, bronze tinted windows, Automated Seatbelt movers, Automated door closers, Retractable Rear Side windows

Optional Features:

• Automatic Transmission
• 6 Disc CD changer
• Deck Lid spoiler
• Faux Wood trim
• Fog Lights
• Leather Seats
• Heated Seats
• Heated Mirrors
• Mud flaps


LS Model Coupe:

In 1991 and 1992 the LS model Coupe was the top line Acura Legend Coupe offered. Just like the Sedan LS, the Coupe LS offered all the luxurious trappings that you would expect from a high line sports-luxury car. Even more luxury than the L coupe offered.

Standard Features:
Driver Side power seating, Leather seat coverings, Speed Sensitive Power Steering, 3.2litre Single Over Head Cam 200 hp (210 lbsft) V6, 5 speed Manual Transmission, 4 speaker audio system with AM/FM Cassette player with automated Power antenna, Painted body protecting trim panels, Floor mats, Moon roof, Body colored mirrors and door handles, bronze tinted windows, Automated Seatbelt movers, Automated door closers, Retractable Rear Side windows, Real Burl Walnut wood trimming, Light and Temperature sensitive Automatic Climate control


Optional Features:
• Automatic Transmission
• 6 Disc CD changer
• Deck Lid spoiler
• Fog Lights
• Mud flaps

1993 was the “Try it out” year for the Legend. In the sedan they tried new colors, revised audio, updated gauge clusters, and a few other things. In the coupe, they tried out the Type II engine and 6 speed Manual Transmission. In 1993, the Type II was introduced in the LS and L Coupe. Making it the first Acura to have a 6speed manual transmission

Also, in 1994 the lower rocker panels were painted on the LS to distinguish it from the L model Coupe.

Optional Colors through the years

1991:
• Cobalt Blue Metallic
• Seattle Silver metallic
• Persian Red
1992
• Seattle Silver

Wheels
All Factory wheels are 6.5” wide, +65 offset
91-92 Sedan (L, LS) - 15", 20 spokes

93-95 Sedan (L, LS) - 15", 16 spokes

91-95 coupe (L), 91-92 coupe (LS), 95 sedan (SE) - 15", 7 spokes


93-94 coupe (LS), 94-95 Sedan (GS) - 16", 5 spokes

Premium upgrade wheels - 15", 5 spokes, availible in gold and silver finish (gold shown)


Offset
The offset of a wheel is the distance from its hub mounting surface to the centerline of the wheel. The offset can be one of three types.
Zero Offset
The hub mounting surface is even with the centerline of the wheel.
Positive
The hub mounting surface is toward the front or wheel side of the wheel. Positive offset wheels are generally found on front wheel drive cars and newer rear drive cars.
Negative
The hub mounting surface is toward the back or brake side of the wheels centerline. "Deep dish" wheels are typically a negative offset.

If the offset of the wheel is not correct for the car, the handling can be adversely affected. When the width of the wheel changes, the offset also changes numerically. If the offset were to stay the same while you added width, the additional width would be split evenly between the inside and outside.

Bolt Pattern

The bolt pattern for the Legend is 5 x 114.3

Acura TL, CL Wheel Info
TL/CL rims will NOT directly fit onto the Legend without boring the centers first.
They must be bored to 70.2mm in order to fit properly.

Misc Legend Info
Gas Tank holds approx. 18 gallons

for all years, theres 2 pegs behind the "A" emblem.
-for 91-92s, there are pegs only behind the "Legend" emblem.
-for 93s, the "Acura" and "Legend" emblems are held with adhesive.
-for 94-95s, the "Acura" and "L E G E N D" are also held with adhesive.

Newbie FAQ Addition #1
(posts 2-11 were deleted to eliminate clutter between main post and this addition, but credit was given to anyone who gave suggestions in those posts)

BHG (Blown Headgasket)
This is one of the most common problems that occur in the 2nd Gen Legends...
Overheating 101
long story short, if you see white smoke coming from the exhaust when you idle or accelerate, its probably a BHG

To fix a BHG is costly as hell , is hard as hell to do yourself , and practically impossible to do without the right parts so many members here would just suggest that you replace it with a completely different engine (preferably a JDM because of low mileage ) or you could spend up to $1500 to take it somewhere to get it fixed, and probably have the gasket blow again on you in 50,000 miles

How do you prevent this from happening to your Legend you ask? Just make sure you do all the scheduled maintenence and take care of your cooling system, DON'T let your engine overheat!

VSS (Vehicle Speed Sensor)
If your speedometer is going completely nuts (showing completely wrong readings or reading 0 MPH)
and your D4 indicator light in the dash cluster is on, chances are, you have a BAD VSS...

the new part will run you between $150-300 depending on where you go (buying new from Acura "stealership" will definately be around $300)

Clockspring (aka cable-reel assembly)
No, this isnt the spring that holds the lil door next to the clock in the console lol
This is what enables the buttons on the steering wheel to work while turned.
If your horns, cruise control, or volume buttons aren't working, its probably a BAD Clockspring...

this part will run you about $270 NEW
DONT buy this part used...most members here who have changed their clocksprings suggest that if yours breaks, don't cheap out and buy a used part because more than likely it will break AGAIN, and in the long run you'll just screw yourself over having to replace the part over and over again

RWD Acura Legend????
*sigh*....before it's asked again, YES it can be done...but it'll cost upwards of $15,000 to complete it...it's really not even worth it unless you just have money burning a hole in your pocket.
(For more information, just search for "RWD Legend"...there's countless threads with the explaination of what must be done and how much it will cost)

Stock Alarm System Problems
If your stock alarm system goes off repeatedly while the doors are unlocked, your door lock actuator has gone bad. To temporarily disable the alarm you can do it with a paperclip. Pop the hood and feel behind the latch for the wire. Disconnect it and stick a paperclip bent in a U into the female end that goes under the radiator. Tape it all up with electrical tape and you are done. Your alarm will now think your hood is always open and never arm.

Vehicle Identification (VIN)

The following is a breakdown of what your 17-digit Acura Legend Vehicle Idenfication Number (VIN) denotes:

Digit 1-3 - Manufacturer
JH4 = Honda Motor Co. LTD

Digit 4-6 - Body Type
KA2 = 86-87 4 Door Sedan
KA3 = 87-90 2 Door Coupe
KA4 = 88-90 4 Door Sedan
KA7 = 91-95 4 Door Sedan
KA8 = 91-95 2 Door Coupe

Digit 7 - Body Style/Transmission Type
1 = Coupe, manual
2 = Coupe, automatic
5 = Sedan, manual
6 = Sedan, automatic


Digit 8 - Option/Trim Package

5 = 86-90 Leather Interior
6 = 86-95 L Trim
7 = 86-95 LS Trim
8 = 93-95 GS Trim
9 = 93-95 SE Trim

Digit 9
Check digit

Digit 10 - Production Year
G = 1986
H = 1987
J = 1988
K = 1989
L = 1990
M = 1991
N = 1992
P = 1993
R = 1994
S = 1995

Digit 11 - Assembly Plant Location
C = Saitama, Japan

Digit 12-17
Individual vehicle serial number

For example:
JH4KA8175RC000001 is a 1994 Legend LS Coupe - Manual Transmission
JH4KA7265PC000002 is a 1993 Legend L Sedan - Automatic Transmission

-ECU Codes-

Getting that little Check Engine lights on your dash may seem a little discomforting. In reality it is really a miracle of engineering and computer technology. Instead of randomly pocking in vast amounts of wires, sensors, and mechanisms in such complex car as a Legend, this little light tells you that your computer knows exactly what is wrong with the car (most of the time).

That means the exact sensor or gate has been pin-pointed as being either partially disconnected or simply out of acceptable range.

Location of ECU on 1986-1990 Legends

The control unit is located under the passenger seat on sedans and under the passenger foot well carpet on the coupes.
The engine CPU is the form of an aluminum box with a little plexiglass window. All you have to observe is a little red LED.

Location of ECU on 1991-1995 Legends

On the 1991-1995 Acura/Honda Legends, you have to jump a service connector located on the passenger side right under the dashboard near the door. The connector has two pin inputs. Connecting them with something like a paper clip will force the check engine light on the dashboard to display the codes.

Extracting Codes

With the car either running or the key in the ON position, perform the necessary steps above and observe the blinking of the light. The light will blink displaying all the codes in sequence and then repeating them.

Reading Codes

The code numbers are read by counting the number of blinks between longer pauses. On 1986-1990 Legends, the code number is indicacted by a series of rapid LED blinks between longer pauses.

On 1991-1995 cars, codes 1-9 are indicated by a series of short flashes; two digit codes use a number of long flashes for the first digit followed by the number of short flashes for the second digit. So a code 43 will be represented by 4 long and 3 short flashes.

The position of codes in a sequence can be helpful in doing diagnostics. A display showing 1-1-1-pause-9-9-9 indicates two problems occurring at different times. A sequence showing 1-9-1-9-1-9 indicates two problems occurring at the same time.

Resetting ECU

Sometimes it may be useful to reset the ECU memory. Although that maybe done by removing the battery for around 20 minutes or so, this will also kill your clock and radio presets. A more elegant way is to:

on 86-90 Legends remove the alternator fuse for 20 seconds.
on 91-95 Legends remove the ACG fuse in the interior fuse panel for 20 seconds. (note that this will also clear the seat memory)

Newbie FAQ Addition #2

Engine Swaps
In theory, if you have the time (and money), just about any engine swap is possible, just most will require extensive bodywork, engine bay work, pain, and suffering, so again unless you have money burning a hole in your pocket, most swaps with other Honda/Acura engines should not be attempted. On the other hand, there are a few exceptions to what can be swapped and what can't:

~All Possible~
- [USDM Type I -> USDM Type II]: Can be swapped easily with no custom mounts or anything...just drops right in (works with Type I ECU, but works noticibly better with Type II ECU swapped also){also works vice versa}
- [USDM Type I -> JDM Type I/II]: Same as above, just drops right in, nothing custom about it. {also works vice versa}
- [USDM Type I -> EDM Type I/II]: Same as above, still nothing fancy. {also works vice versa}
- [Type I heads -> Type II heads/intake manifold]: Possible with a few modifications, this would turn your Type I into a Type II...its just alot easier to do a complete swap than to modify all this.
- [Legend Type I -> 96-98 TL/Inspire]: Totally possible, since the TLs from these years shared the same C32A Type I that the Legend used from 91-95.

~NOT Possible without serious money/time~
- [Legend -> 96-03 3.5 RL/Legend]: Possible with money, and has already been done by member 'DV8' (do a search).
- [Legend C32 -> NSX C32]: Requires SERIOUS money, since this C32 engine is wider than the Legends C32, and would require the rest of the car to be completely modified to accomodate this engine. The intake manifold isnt swappable from the NSX either.
- [Legend -> 99-04 TL/Inspire]: Completely different engines...Legend uses the C block which is laterally mounted, TL/Inspire's use the J block which is completely sideways (transversely mounted).
- [Legend -> 96-03 CL]: Same as above, the CL uses the J block also.

and remember, the Legend's engine is a 6 cylinder, and these heavy bodies need hp and torque...not really much point in trying to throw in a 4 banger from an Integra or Civic...unless your heart is really set on it and your pockets are burning your thighs.

But still, just about anything CAN be accomplished if you have the money, boredom, and time.

great! its ok to stomp on the info, especially if theres somethin wrong with it . Most of the info here wasnt written BY me, its just general stuff that has been posted around the forum for a couple of years that i compiled together because many people are too lazy to search for themselves.

thanks for actually calling a dealership and confirming it....editing now, and adding your name

Well, if you're in the process of editing, you might want to add this to the chassis codes or body type for the G1 under Digit 4-6.

KA2 = 86-87 4 Door Sedan
KA3 = 87-90 2 Door Coupe
KA4 = 88-90 4 Door Sedan

EDIT: For those of you non-USDM or Japanese owners, these chassis codes might help you;

KA1 = 85-89
KA5 = 88-89 Ti (turbo)
KA6 = 89 V6xi

I am not 100% positive on the last 3, but they should be right.


BTW, thanks for compiling this info. It has helped me a few times.

Daddymac117

cool, its edited, and added you in

and im always in the process of editing...if anybody finds any info they think should go in here, or finds an error in somethin i posted, i dont have a problem adding something in that i forgot or fixing something that was wrong. The point of this thread is to get accurate general knowledge to members as easy as possible...not to make me look good lol.
