Do any of you techs in here know how much hp the stock 4l60e can hold b4 it destroys itself???

 

Does know if this will help
On the older body style trucks - the same thing happened
There was a TSB about it
If you removed the drive shaft - then filled the rear of the
yoke (about .5 to 1" )(not the entire thing)
with a heavy grease like cv grease -
the bump will go away.
I did it to many trucks
Supposedly on rapid decel the output shaft and yoke
come to rest in a slight bind - the bump is the yoke after the brake
is released.
Dont know if this true for these trucks - but worked for me on the OBS.
FYI

 

That lube does work but I heard it doesnt do the transfer case clutches any good when it gets hot and mixes with the fluid. I would say it needs a nickle plated slip
yoke to correct the famous bump/clunk.

 

Maybe 375hp before the 3-4 pack goes. If you don't slip the clutches or band, you'll begin to break internals in short order with hard launches.

 

Thanks Hit, much appreciated!! So should i go for some servo work then or do you think i should wait. I am planning on getting that L5 tranny from FLP anyway so...

 

Well considering you're pretty much stock w/ a few bolt-ons, get a TransGo and servos in there to see how long it'll last. I bet a long time.

I'm going to see how far a TransGo + billets can take a stock internal 4L60E. I have NO TqMgt and it's fine still...granted I dont' have a lot of power but I'm not stock either.
