GM Supermatic Trans
In the latest issue of the GM Parts Performance catalog there is a new Trans available. Not sure of the cost but they do give a 12 month warranty. The 4L60E/65E were only rated to 380 ft-lb of torque and the new one is suppose to be considerably higher.
If the price is reasonable (sic), this could be a good replacement for someone who wants to drag race and not worry about rebuilds.

I figure if it's GM, it's at least $2500, maybe $3k. I couldn't read that P/N either, only made out 5 or 6 numbers. Noticed they said u need TCU P/N as well.
Nice to know their realizing we need a step up. I thought the 60E was 360Tq. rating, but I've been wrong before. Could be rated higher on the 65E tho.

I believe its grossly underrated at 440 ft lbs. I say grossly because they are severely handicapped by the insanely soft stock shifts. They put the 80e behind the 8.1 in the Avalanches and Suburbans and the duramax in the G vans (actually a 4L85E).

I don't think 440 is under rated to much i was pushing 500 through my 1500HD with a 80e and it didn't last very long.
I always thought that the 8.1's had the allison behind them cause i know for sure my 02 2500HD truck did

Well I think the 2500 Suburbans and Avalanches have a different chassis then a 2500 truck does. I know the half ton chassis are different and maybe that got carried over to the 2500 SUVs so the 80E was an easier option to make it all work.
