A 4L80E is unnecessary at your power levels.
Martin
Meh 6L80s are garbage shifting and can't really be built yet to handle any decent power like a 4L60 or 4L80. I finally have a good trans tune on mine and I still think its crap.
I don't have one yet, when this front end blows up I'll be looking at upgrading to one. Blowing up a 4L65E and a 4L60E makes me wonder if the proper trans is a 4L80E for this truck.



Pulled this thing out from being parked for 2 years. We are planning on putting this and my truck on a trailer for blazer bash.

I was going to say something similar.
Ben,
The first year I owned my K5, there was a lot of clusterfock BS. Almost burned that bitch to the ground several times. Had the motor, tranny, and transfer case apart more than once each.
In the end, when everything was sorted, it was a good rig, lots of years of good use.
You can do this, it's worth it.
Hard to believe the trouble you're having with this... good for you for not going postal yet!? Lol!
You will get there! Take it easy Ben!![]()
Wait...what's the story here?![]()

The statement about a 6L80 isn't true anymore. There are several guys running 6L80's in their buggies and specifically Ultra 4 cars, I want to say at least 5 to 10 of these are being used now. They are being built to hold up and shift well. 5 years ago the first couple guys were making a go at these and did struggle a bit, now that the work has been done there are ways to make these work well. It isn't cheap and easy yet but the stuff is out there.
A nice 4L60/65 shouldn't be any issue for you Ben, you think you beat your junk but you don't. Yes a 4L80 is better but if you can't afford to build one then you're going to be just fine with doing a 4L65.
