Atx problems

[Racin Repair]

I just bought a 95 3.2 auto. Not sure if theres a post somewhere on here addressign this or not.

My trans sometimes upshifts very early ( 3k) under full throttle and sometimes it will shioft normal. Down shifts hard sometimes and others normal..

My question whats prblematic on these? I would think its computer controlled if so do I need a new tranny module/pcm ??

Any help would be great!

Mine did that once at the drags. Not condusive to good ETs when your tranny's in 3rd already at 40! I never did figure out what the **** was going on, but it seems that either a faulty Vehicle Speed Sensor (VSS) or neutral safety switch can cause this.

are you throwing any codes?

when i first bought my taurus, it'd run fine for a while, until it got up to normal operating temperature, then it'd start shifting erratically, downshifts whenever it wanted to, upshifting... i forgot if that was any different.

anywho, it turned out to be the vehicle speed sensor. they go out on these cars quite often, on the automatics. it's a pita to replace. haha.

Thanks, Ill check and see if theres a pending code for the VSS. No light yet.

Werd on the VSS. Mine was doing that too when I got it. Bought another SLO one time real cheap because of a bad VSS too :angelnot: Transmission range sensor can do similar stuff too...I had the luxury of verifing what was up with mine with the scantool at work

was the VSS. Thanks guys!

Took about 40 minutes to change that buried bast@rd out!

how did you do it? did you drop the subframe or just reach in there?

Just reach in. Its a pain but but do-able
