• The site migration is complete! Hopefully everything transferred properly from the multiple decades old software we were using before. If you notice any issues please let me know, thanks! Also, I'm still working on things like chatbox, etc so hopefully those will be working in the next week or two.

Trannyman please help

My tranny is destined to fail very soon I can feel it but I think i found a replacement has about 90k on it but I need to make sure it is the right one. I have a 1997 GTP is it the 4T65E or 4T65E-HD that I need???:th_scratchhead:
 


Just as mentioned above, you do have the HD version. 97s-only used the 4T65E-HD in the supercharged cars, all others this model year where just a 4T60E
 
I believe the 97 Regal LS (non-supercharged) used the standard 4T65E. Of course, that was considered a 97.5, so maybe that's the difference.
