guy's what kind of power can the 4l70e trans hold up to in a new body style silverado 4WD with the 6.0.. I am thinking of adding some power to this toy. I have a Nelson tune and i love the way it shifts but im thinking with a little more juice things are going to break and want to get out ahead of it.
Thanks
Shift kit & servos will handle plenty.
Here's a kit you can install yourself: https://www.700r4l60e.com/store/home.php?cat=58
Dana has the experience to help you mod yours to handle up to 900HP (less without breaking into the case). Give him a call.

I don't know this person but he lurks on this forum often.
FLT is the best in the country. I have one of there transmissions and have beat the crap out of it with not even a sqeak.Quote:

With the 4l70 a shift kit and a vet servo are good upgrades to add to the life of your transmission. I would also recommend a set of aluminum accumulator pistons be installed while doing the shift kit. With this combo the trans should gain some added strength basically until you break it. Good luck with the truck. VinceQuote:
