what trans do I have?

I have a 98 GT and was looking for parts. Do I have the 4t60 or the 4T65E? Where in the VIN, if any will this tell me.

Best place to look is on the SPID label located on the back of the trunk lid which has all the the RPO codes listed. 4T60E is M13. 4T65E is M15. Also, the 4T65E will have a bigger umbilical cable connector located at the top of the driver's side of the tranny facing outwards towards driver's side versus the 4T60 which is smaller.

should be a 65E in a 98 but if it is early 98 production could have either

Yeah, I've run into a few '98 GPs with the 4T60. At least the GTP had the 4T65E-HD (RPO MN7) since introduction in 1997.

The sticker said M15. Guess at least now I know what shift kit to get. Thanks guys.

I was just wondering what are the differences in the 4T60E and the 4T65E????

lots of minor things, big stuff is case, valve body, 2nd clutch drum, line pressure is computer controlled, shell (stove pipe) Planet (how it attaches to the shell). All in all nothing is really too different between the 60E & 65E besides design changes on parts.

OK. Thanks for clearing that up.
