Well I know I'm not making power any where close to needing an 80e and even if i was approaching that point I'm not capable or willing to do the swap at this time. I'm just trying to get any suggestions on what may be the cause of whats happened and what,if anything, I can do to avoid an entire rebuild. This is only my dd and will not make enough power to need a "performance built" transmission. I just have to figure out where to start looking so I can figure out what to do. I'm gonna call a few shops and see what a rebuild will cost me, but I may still attempt it myself I just really hate working in the cold.

You are incorrect here. I have a friend who has blown 3 stock 60s with a stock motor and no tune. Regardless of how much you think you need... go with an upgraded 60e. Have a decent one built because with a 60e, it isn't IF, its WHEN.

Do you guys think I'm looking at a rebuild? and if so what could be done to build it a little tougher? I've never had much transmission problems so I still don't know much about them.

you know after reading your post over again, it is odd how it broke if thats what it is but it does happen, do you have any vibration issues before this happened, i see your dropped? how much? i take it the rear end is stock, put the truck on 4 jack stands, drop the drive shaft, see if you can turn the rear tires, i would check the rearend first, before just pulling the tranny.. just cause it sounds like its coming from the tranny it could be coming from the rearend, if that pans out to be ok drop the pan, if you did break something in the tranny i am more than sure you'll have some type of shavings in the pan..

I have rebuilt several 60e trans with no reverse there is a drum in there that is bad to brake. When it brakes it will have only 2 forward gears and no reverse. It has been a while but I think it is 2nd and 4th you have or is it 1st and 3rd... There is an aftermarket drum that is stronger available.

That was my first thought too.

Ok, since you have already heard the list of good builders--either get one from them--or do you have a local guy who will build it? If so get a waaay stronger fully built input drum from PATC and this kit.

Good luck.

My immediate thought was that it was the rearend but after messing with it i'm pretty sure its the transmission but I'll check it all out tomorrow when i get some free time. I called a few local rebuilders today and got some rebuild prices that ranged from 1200-1500. One of the guys I talked to said it sounded like the reverse sun shell was to blame and that if that was the case it would cost about 1,000 to fix just that. I was thinking about ordering one of these and build up/repair my current trans. as I get time. $1134 shipped, seems like a good deal, but at 1600 the performa built may be the way to go.

When installing a new 4L60E, you should also install a new torque converter at the same time. True or false?

Its all in how you wanna do it. You can purchase all the performance parts online for under $500 and then remove the unit from the truck yourself and take it to a builder who will assemble it for about $350-$400.

Sometimes. Depends on the reason for the new tranny and if any modifications have been done to the motor to warrant a higher stall speed.
