• 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.

03+ 4t65 transmission



No.

I don't remember all the year differences to explain it in detail, but I think 98-00 is different from 01-02 and 03+ or something like that.
 
I've broke one in an 04 and one in an 05. The 05 was bone stock, never abused.

If you want a stronger trans, you need to get a built one, or build one yourself. TripleEdgePerformance is a good place to start.
 
97-02 are the same, the trans line connectors are different after 00+ and maybe a minor change in a PCM file for it.

03+ transmission have a different valve body and a hardend 4th gear. The PCM controls the trans different aswell.
 


You can use an 03 trans in a 98-02 car of you use an 03 PCM / trans cal and the trans range switch off a 98-02 trans. No wiring changes needed.
