Do you think the trans will hold up as long as it stays on the street? I worried that it might fry the trans with that combo.

Tell me the truth. Are you really going to stay on the street?
Just put a big cooler and get a tranny temp guage and keep it out of overdrive in the city. The main thing with 700r4s is to keep them cool.
I have a 700r4 and 36s with 4.56s. If I ever re-gear I would go to 4.88s with this tranny.

This is for Donna's truck. I was thinking about just slapping a lift on it and the 36's before swapping 1 ton axles in with 4:56's.

Wayne,
I would just doing everything in one shot, it will be so much easier; this way you do not have to remove the axles twice. If you do not put the 1 ton's in at the same time, make sure Donna does not use OD.

Speaking from the perspective of someone who builds a lot of 700 R4 transmissions, I can say that a stock or stock rebuilt will not live well. Even a well built one would be far better off if you had 4.88 gears. And a HUGE cooler. I have some built units out there that have more than 100K miles on them, but they are far from stock.
