4l60e to replace 4l80e 2000 Chev 2500?

Tomorrow I’m bringing the truck to my shop. Shouldn’t take long to figure out if the trans is junk or not.
I’ll get it up on the lift and can get a good look at what’s going on.

It’s in my shop up on the hoist, checked the cable seems good.
Talked to a trans rebuilder he gave me a few things to look at. But suggested that a couple frictions welded them selves together making it go forward in all gears.
I read that someplace as well.

Tomorrow I’ll take the pan off. I got sidetracked moving snow on my yard.

Yikes!
Calling it done… I’ll rip it out this weekend.

A few hard bits in there?

Actually no, nothing exciting. Fairly disappointed. That’s just dirt from taking the pan off.

I wanted carnage!

Looks like my previous th350. I flushed it a dozen times and it always looked like that. Ran great and never slipped.

I’ve had a couple th 350s and a th 400 that gave trouble changed the fluid new filter and good to go.
Not wasting time on this, not my truck and its got problems i never experienced. Boss said get a different one. 10/4 Boss!

I've seen worse th400 that survived long after

Ordered a rebuilt, waiting on it.
In the meantime went ahead and took the transfer case apart to check for pump rub…. Almost went through the case, and the chain is shot.
Glad I know how the Gm of the era cases have their problems.

Ordering a new chain for it and I have a pump rub kit we have been saving. So it’s going in too.

Where is it that the pump rubs the case? I’m not seeing anything worn?

Left hand side on the first pic Dave. Hard to see in the picture but it has worn a mm or two off the case , not much more to make the case leak .
The factory clip is the stainless piece on the bottom of the picture, it suppose to sit in that spot, it fell off they usually just snap in half.

Ok, I see it now, I thought that was an additional metal piece still in place in the case.

Yeah that’s the spot alright.

Caught it just in time.

Just working on it in my spare time when I feel like it.
Got it back together yesterday, all stock and happy like it should be. As long as that LS 6.0 lasts anyway.

Glad we didn’t decide to swap to a 4l60e seemed like a pain.
