I dunno how many times Ive tried everything I just cannot get it to work...but today I had some progress I think...it jumped a little bit when I connected the green pulse wire to the brown D wire on the Cblock connector to the dash....

remember this is a 90 trans am with a 93 lt1 and 700r4...all a working combination stock in 93'...

Any suggestions???...

 

what VSS are you using on the trans?


also, the PCM will need a VSS signal as well.

 

which vss??...what are the options...im really not sure...its whatever was stock im assuming.
