question about si tranny.

So my car is supposed to have an si tranny but it runs at about 2500 at 60 in fifth and I heard an si runs at 2900. I'd like to figure this out.

So I plugged in my gps and it actually runs closer to 2750 at sixty. My speedo runs slow for some reason.

If ever you take your transmission off, count the little teeth groves on the throwout bearing shaft(splines). Should be 21 all the way around.

My apologies, i meant 20 splines on the output shaft

Just so happens I have to replace my throwout bearing. I'll look into it

Very well!  The 88s are 21 splines and the 89-91 are 20 splines. lets see what your has and we shall go from there.
