We towed it with a strap back to the shop and i didn't hear anything grinding or dragging.The most power its had in the past year....being towed by a new ram lol. I know I read line pressure could be an issue, it does have a firm 1st to 2nd shift, but surely that shouldn't be enough to break the pumps, especially in a "built" transmission.
The sensors are very different on the axle side. Also i doubt the wheel count is the same.

Is it a built 4l60?

I feel its very strange that theres no information regarding this specific stabilitrak issue. Is it possible a sensor somewhere else is unplugged or a wire got rubbed threw?

It is an RPM level 5 transmission. That is who also verified the convertor would need 1/8 to 3/16 washers.
The convertor is a circle d.
They look everywhere on the lift. Even pulled the tank to put the new pump in.

My vote is the sensors or a poltergeist. Not sure how you fix either one though lol.

Transmission that really sucks I hope they warrantied that

Sounds like you're answering the ST issue for yourself. The light coming on before the truck moved indicated sensor values/resistances are not what the truck is expecting to see.

Might be able to just add some resistors or something to fake it into being happy.

However since you said its reading the correct speed that is strange.

Did you ever find a solution to this? Just did AXN from an 09 Caddy into my 05 Yukon XL and I have exactly the same problem. No ABS activation + a big *** air bubble stuck in the module stopping me from bleeding properly. Can't run the ABS bleed with those DTCs present and I can't clear them. Reading constant 3 mph from the sensors no matter the speed. Truck needs to haul for 20 hours of driving next week....

I sold the truck a long time ago. The transmission broke its 3rd pump and I had enough. I don't remember having a problem bleeding the brakes tho. Although this was 4 years ago.

Thanks for getting back to me. Yeah I hear 4l60s are pretty much dead ends after 400 wheel or so. I threw this axle in because it was cheap and I read it was a direct swap. I'm not even considering turbos until I can afford a full 4l80e or I have time for some kind of even dumber swap. Mostly she sees duty hauling things for a kids nonprofit I run. I'm sure I'll have to do some kind of redneck electrical engineering magic to get the lights off. For now I'll bleed it the hard way and just avoid towing
