4L60 Stock strength
Hey Everyone
Im sure its been asked many times, Ive been searching and cant seem to find much. I'm looking to maybe do a 5.3 or 6.0 swap from my 4.8, and want around 400hp crank hp. So im just wondering if the stock 4l60 will live behind that, or am i asking for premature failure
Thanks
Mike

You will never get a definitive answer on how much a stock 4L60E can hold up to. Numerous people are running at or around 400 flywheel HP on stock 4L60E trans with no issues, and some people some how toast stock 4L60E trans with a stock truck lol go figure.
With you being a ECSB it is a heavier vehicle and the stock 4L60E may or may not last you awhile with that much added power. Your driving habits is a factor too. I would get a tru cool 40K trans cooler and just run it.. Later on you can slowly put away a little cash each month or so and eventually get a built trans and get a converter. Also you can keep the tune a tad on the conservative side to try and prolong the stock trans if you wanted.

Ive been reading about the TM in the stock tune, and how it can be pulled with a performance tune. I think even with new cooler, servo, and shift kit, id most likely pull at the most 50% TM just to be safe. Im not super hard on my truck either, I dont like beating up what I spent my hard earned money on, I just want some good solid power when I feel like getting into it. The 4.8 in such a heavy truck just takes to long to get going, espcially driving around town.

its my daily driver. i have a cricle d 3200. with corvette servo shift kit and converter truck is amazing. it is very driveable on the street but when you floor it its a whole new truck. with my tune and all these mods im chirping 2nd with my 26" rims. not bad for a 4.8. make sure u get a trans cooler. id reccomend the tru cool 40k. its a beast, never see temps past 170 even during hard driving
