I just recently changed out my VSS. It costed my 80 bucks at acura of agusta and another 20 to get it changed.

to those that think that the VSS doesn't affect anything els other than the speedometer, well then YOUR WRONG. It does affect the transmission shifting more or less so don't hold out too long to change the VSS.

When my VSS was bad, my car was shifting strangely upon take off. This was more noticable the longer I left the faulty VSS still installed in my car, the longer I left the faulty VSS in my car, the worse the speedometer got and the worse my transmission felt.

Now that it's swapped, no more crazy speedometer and no more strange tranny shifting upon take off.

just an FYI

Hello,

I am a new forum member. My wife has a '92 Legend L sedan (53K), purchased last year. We are getting the speedometer needle bounce and flashing shift indicator lite problem. I haven't noticed any transmission shift problems. Can anyone give me directions to the vss itself, parts I need to remove to find it, and some idea of what to look for? I looked thru my Chilton's but didn't see any mention of the vss. Acura of Augusta told me it's on the transmission-that's all I know.

Thanks,

Dave

If memory serves, the VSS is located in proximity to the oil filter. You can't miss it. I had trouble with the top phillips screw holding the "gut" (pick-up) to the VSS body, so just removed the unit. Had to use a brass drift to gently tap the unit a 1/4 turn LT, then RT a few times before I could pull it out of the diff. In doing this, you will seep a bit of diff fluid. You also need two dowels or something to block the two hoses which you will disconnect from the VSS. You will leak transmission fluid.
With the VSS off the diff, the repair takes about 5 min.

You need to use every part which comes with the kit. Especially the new gasket.

oh so those hoses are filled with tranny fluid? i thought they have powersteering fluid in them.
do i also need to replace the rubbor O ring on the part that goes into the diff?

If you remove the VSS body from the diff you are supposed to replace the O-ring which comes with the kit. If you don't remove the VSS body, you don't use the new O-ring. The new VSS is packaged with an illustration sheet which will show you how things go back together. This repair is a "no-brainer".

yeah, looks easy, but their description is terrible! how do i get the rubber ring on and off? do i just stretch it and pull it off the end?

Yes, very carefully.

I've been having problems with my speedometer but not sure if it is becasue of the VSS.

The speedometer works fine up to about 50mph. From there it gets progressivly "off", like this:

reading actual
55 57
60 63-64
65 59
70 63
75 67
80 68-69
over 80 it gets really off.... I tested the reading vs. actual by having people pace me and also testing at a 1 mile test section of straight highway near my town.

Also I've only noticed this once or twice but the speedo will jump up or down by 10 degrees and then return while driving. Could the incorrect speed reading be from the VSS or do I possibly have comething else going on?
