Hello, I have a 6l80 transmission that I just completely repaired. I changed all the gears and also the reverse gear, but after 20 miles it started to give me the U0101 code, but even with that code it continues to work well. I have checked the two connections inside the transmission and they are fine, but I cannot find the ground wire for the TCM. Could you help me or give me an idea of ​​where the problem is? Thank you very much.

How is it possible to have a permanent code u0101 and still able to drive the cruze with no issues is it possible that its low on fluid,I did find a mouse house under battery tray but my obd tool removes code and it comes right back but car still shifts and drives ok. Is it possible mouse has chewed something and im not finding it. Battery and Alternator check is good so is fuse is good,maybe it's time to unhook tcm from harness and inspect wiring should I also check wiring going to fuse block. The mouse house was under battery tray near two harness pigtails going to ECU.

I get that code for my 2011 Nissan Murano U0101, P0746, P1778, I change the transmission fluid & filter , I cleaned all the ground wires by the TCM & terminals! I also check voltage for the solenoids in the valve body. Everything is good !!! I didn’t reprogram the TCM commuter tho. Can anyone help me pls. My transmission does go passed 1first gear ! I think it’s on limp mode ??? Can anyone help me pls.
