any 4t65-e thats a NON hd I believe had 3.29 gears which your car has their are a few models that have weird ratios like a 3.09s Triple Edge Performance has the conversion charts to tell you what trans missions will fint it what. All you need is the ID tag off your trans and then compare it with the Id tag on the trans your looking to buy to make sure they have the same gear ratios. Ill see if I can find the link to the conversion chart and Trans ID tag info.
