I built a 4L60E with every up-grade I could find, i.e. "The Beast" sunshell, 5-pinion planets front and rear and almost everything else available on the aftermarket except I didn't go for the stronger input shaft with the aluminum shell (I can't remember what it's called). For street use only how well do you think this tranny would hold up to a stock LS7?

 

Very good question! I also did every upgrade possible to my tranny(except input shaft) and i am putting in a LS7. I'm interested to see what people think? Traver

 

It will work, but for how long, I don't know, give it try and tell us what happened.
