Your probably going to want the tranny to shift pretty hard as well, so your probably going to need to be able to bump up the line pressures on the trans in the pcm and on the trans itself. Probably going to need a steel channel plate gasket to handle that.

Is the car N/A, s/c or turbo? There are torque converters zzp sells, but you may want to go with a custom converter.

300m input shaft, hardened output shaft and pump shaft. Most transmission builds of the 4t65e don't last very long when built by someone else not experienced with this type of trans. We have zzp, triple edge performance, tim king at intense racing and a few other shops around the U.S. that do excellent work on the 4t65e's.
Thanks for the tips. The car is about 2700lbs, engine is n/a, no s/c or turbo. I may run a bottle if I ever get a trans to hold. Dont plan for more than 600hp about 450 now and may do a 383 stroke in a few years.

Zzp is about a ten minute drive for me, I was planning to do the trans build myself however I've been really busy and never been inside the 4t65e. Best be smart and just sublet it over to zzp.

Does the 4t65e have a sweet year to use? h/d or not?

I will be using a stand alone controller to run the trans... fill me in if you a recommendaton, I was thinking the pcs unit.

Thanks,
