This is the link from when i did my 92auto. 2.59 to 3.54 upgrade. you can go to 3.75 if you want. a little harder on mileage on the highway. a little better for drag racing. with 3.54 i can autox the car on slow speed courses and just leave the shifter in 2. you'll be right up in the power band.

Btw, if you have a 92 then you should have the 700R4 tranny. as far as i can tell the 4L60E comes out in 93 or 94.

4L60E or 700R4?

My RPO's listed my car as having the 4L60E tranny as well. I had it rebuilt 2 months ago and found out that it is a 700R4. As far as I know (which granted isn"t much) '93 was the first year for the 4L60E. Unless you have physically seen the stamping on the transmission case, I wouldn't always trust the RPO's.

I got the Number off the tranny and it is 2 YC M 093 B,which i do believe translates too, 92 year, YC is model # ,M is (4L60) , 093 is the day of the year it was manufactured and B is made on 2nd shift,If any one has a different translation of this numbe, I welcome your input, thanx.:beer
