Are the gear ratios for a V6 cutlass supreme sl the same as an 88 SSE? I took the tranny frm the cutlass and put it in the SSE, I was told their were interchangeable. The car shifts fine with some adjustments I made to the TV cable and vacuum modulator valve, they just seem a little higher than what I have heard many of you who are experts here say they should be. I am installing a new tach to check and see if mine is reading correctly. I will chk your responses and give you my findings tomorrow.
