2001 Mustang GT Transmission Identification

STCompDude · 03-25-2008, 06:55 PM

I've got a 2001 Mustang GT convertible that I want to upgrade with a short shifter and eventually a new clutch. I read on AmericanMuscle.com how to identify which transmission I have, but unfortunately the door jam tag on my car is faded and I can't read the transmission part of it. Is it possible to ID what type of transmission I have from the VIN number or is there any other markings on the car or the transmission that would tell me which one I have?

Thanks!!!

what is the production date of your car? It should be on the door jam label.

Randy might be able to run your VIN to see.

Production date is 12/00. That's about all I can see on that tag. Also, what's the biggest difference between the T-5/T-45 and the T-3650?

you have a T-45

I have the T-45 and my car was built in April of 2001. The earlier cars had the T-45.

I think they switched to the TR3650 after 2/01 (or 1/01). There is little difference visually between the two (don't group the T5 w/ the T45 since both are different) but there are subtle differences (not sure what).

Its easy to tell if you have a 3650 as the bellhousing is cast into the tranny. So instead of having the bellhousing separate it will be part of the tranny case.

According to TREMEC's site though, they say the bellhousing is integral for both the T45 and TR3650 (and the TR3650's housing isn't cast into the tranny since on my 03, I can clearly see the excess silicone where the bellhousing and trans meet).
