Transmission advice

[Jacob Hickman]

Hey this is my first forum but I have a 99 k1500 classic so it’s pretty much a 98. I just lifted it and but 35s on it I pull trailers here and there but I’d eventually like to start taking it mudding. My problem is my 3-4 clutches went out in the tranny like many other 4l60s, should I replace it with a brand new Gm 4l60 or go with a built one from an aftermarket company if so which ones are good. Thanks for the advice
If anyone has a mud truck with a stock 4l60 how does it do

4L80E is always the answer.

Any tips on picking a 4l80 and swap for my truck I’m looking rn but hard to find

Try https://www.car-part.com/. They index salvage yard inventories all across the USA. I picked up a 4L80E from a salvage yard out of a truck with 300K+ on the odometer and it's still doing great in my red truck.

If you're looking for tips on what all is involved in the swap I have a thread here on the subject. I had my mechanic do the install but I researched all the parts. This was on a 2WD truck so you'll have the transfer case and front driveshaft to deal with in addition to everything mentioned in here.

If you are looking to fix it cheap, I know a guy in Springfield IL who will rebuild and put it in for $1500 he had my truck done in less than a week. He also gives a 1 year/12k warranty even if he doesn't install it.

4L80 all the things! My swap came in around $1400.

You should add: "4L80e swap" to your poll options...

Lifted on 35s trailer towing and mudding tells the whole story bud.
4l80E and the best one you can afford.
The 4l60e isnt even on option.
Thats like reading a 4l60e cooking recipe
