Hey, I just registered here but am having the same issue with my 19 Yukon. Did swapping a new trans fix the issue? I took mine to the local GM dealer and they said they done see any problems with the trans other than the code showing. I've been looking over @NickTransmissions thread on these as well

Hey how's it going? Welcome aboard
After changing the solenoid it helped a little but in the end yes changing my torque converter did solve my problems.

Need to wash and wax the thing, trailer as well. That paint is showing it's age (5 years) but I'm just going to wait a few weeks. We're just beginning the Great Pollenation down here. Probably just wash the trailer, get it detailed and the paint restored when we get back in August. Looks like that will become a regular every 5 year event; not safe to get on the roof any more to cover it up.

Gave it wipe down with the spray wax. Downside of compounding a whole truck is the ungodly amount of it everywhere. Even after a power wash. Also discovered my barn find Uniden CB Radio I was going to put in the Yukon is dead..But I have a Motorola brand new in box to put in instead. Also C10 is Anxious for warmer weather.

Added 1.5" leveling blocks (the round kind) to the rear, to fix the squat after adding the 5100s to the front.

Ordered the wrong size rear swaybar bushings, but when I pulled out the current rears to replace and add fresh grease they looked fine compared to the fronts.

This sub-forum is for 2007-2014 SUVs. There is a dedicated 2015-2020 forum for yours, which may be a better place to ask.

No issues with any of the bolts? One of my front ones snapped off on me when I did mine. I had to drill it out and use a nut and bolt.

Which bolts are you talking about? My rear sway-bar bracket bolts (the 10mm) came out fine. When I replaced the front bushings a year or two ago ??? there was a mighty struggle when one on them broke. I've since dropped a bit of anti-seize on them.

Yeah those bolts for the mounting brackets.

Yep, one of the front guys snapped. IIRC, it was the passneger side...? There's is a pocket above the bolt hole that traps all sorts of schmoo, and rusted the bracket bolt up good. The old bolt was fused in there, and I ended up drilled out a few milimeters to the side, and tapping new threads, and the bit wandered a little and didn't go exactly through the middle of the broken bolt. The braket is still basically in the same location as originally.
