I'm getting a 2006 RCSB Silverado that I'm buying from my parents in a month or two, and am wanting to beef up the tranny so that I won't have to worry about blowing it up with low miles still on the truck. I know for sure that I will go with a 2800-3200 stall torque converter (Daily driver, but will be doing a cam and forced induction eventually) but will leave the 3.23 geared G80 in. I am looking for mods to do inside of the tranny itself to build it up once the warranty is done (next August) to support ~500rwhp. The truck will stay a street truck and will not see really high boost (still haven't decided on S/C or turbo) just something to make it a quick DD.

Things I have considered were the converter, ~28000 BTU transmission cooler, deep pan, and Transgo HD-2 Shift Kit... Not too sure on these, but any help is appreciated.

My trans took a dump on me so i have been wondering the same. A lot of people are saying to just buy a new trans from finish line transmission.

 

80e's are bullet proof

no such thing as a bullet proof 60e lol
There are strong ones though (FLT)

 

Put a vest onit!

 

The truck only has 9,000 miles on it right now, no sense or need to buy a new transmission.

As I said before, I am not needing to buy a new one. And I am definately not going to be at a power level that an 80e is justified at.

 

an 80E is justified at 500rwhp. 5000 lb truck plus 500rwhp = RIP 60E (or rebuilt often).

 

A vette servo seems to help alot. If you go turbo the 3.23s will be fine. If you go s/c better plan on a gear swap.

 

What gearing are you running in the truck Dave?

 

your G80 rear end will explode one day if your trans does not. I did the full TransGo, pistons, and servos with the spacer. If you're serious about 500HP those are the two things that will go first. The trans for sloppy shifting, and the G80, for the stomp and goes, and burnouts.

 

Pretty much what I was gonna say. Wrap it with kevlar!
