talk to any tranny rebuilder. Of the ones that I know and have seen talked about here before there are:

Gear Star Transmission
Finish Line Transmission
RPM Transmission

they all make upgraded 4L60Es, but I think if you're shooting for ~425 rwhp I think you might want to consider a stronger tranny.

I smoked mine in my '95 Z with about 380 rwhp. When I sold it, it would still shift but not at WOT. I even had the 24,000 cooler on it. Only 46,000 miles too.

My Rock-On 4L60E has lived behind my 600+ hp for a long time. I've gone 6.7s with it and can't tear it up.

I've been through 3 4l60's in a year. A stock one will not hold up to any kind of power. While I agree a proplerly built one will, a stock will not. At least not for long.

Either spend a LOT of $$ on a well built 4L60e and cross your fingers you got one of the good ones OR get yourself a 4L80e if it see's the street a lot or a th-400 if it see's mostly track use only.
