Ignition Coil question

*sam o nela* · 05-30-06, 02:38 PM

Hey guys I've got a quick question....what does your guys' coils say on the side...

TC-04A or TC-09A ??

I was previously under the impression that 86-87 2.5's had their own coil, while 87-89 2.7's had their own coil and 1990 2.7's had a coil all their own...

Well I come to find out that my 87L (2.5 Manual) has TC-04A AS DOES my 88L Coupe (2.7 Auto) parts car!!??

??

So can you guys go take a looksie for me real quick and post up your coil designation, (its stamped on the driver's side of the coil right in the center...cant miss it) and your car's year, trim level, and transmission??

I need to know just who's got what....

ok heres my 90 automatic is tc-09a and ma 87 automatic is tc-04a ... there ya go

1990Legend_LS_5spd · 05-30-06, 04:26 PM

im pretty sure that only the 1990 automatic cars had the TC-09A coil. My haynes manual states this as does Mitchell On Demand 5.

TC - 04A

90 LS 5 Manual Coupe

TC-09A 90 Coupe 5-speed. But one interesting thing I see sam is that both coild have all the same operating specifications, just a different plug.

*sam o nela* · 05-31-06, 03:18 AM

Wait....so Eric has tc-04a but Lenny has tc-09a?? Both 90 coupe 5 speeds but with different coils? Now THATS intereseting....im assuming that between the two cars it will come down to month of manufacture....

You sure that car wasnt an automatic in an earlier time? Manual transmission cars kept the TC-04A coil while only the automatic cars had the TC-09A. You can look this up on www.napaonline.com, search 1990 Model year, Legend, and you will see 2 different coils listed. Yes, the coils do appear to be the same although the primary and secondary resistance levels are different.

^^^^ God damn I think he's got the answer!! Thanks man!!

1990Legend_LS_5spd · 05-31-06, 03:42 AM

No problem. my haynes manual also states that the 1990 automatic had a different coil with a different connector. i still dont know why they went to a different coil for that last year.

*sam o nela* · 05-31-06, 03:44 AM

Im assuming that the resistance and output was better suited or worked more efficiently with the new Tranny TCU?? just a guess....

1990Legend_LS_5spd · 05-31-06, 03:47 AM

im not really sure, altho i know the resistance is higher in the TC-09A on both the secondary and primary windings.

body9599 · 05-31-06, 10:52 AM

are we thinking gains here with a swap?

Nope, comes up on owner's link as a manul. But the build month and year are AUG 1990
