Great information. Thank you

Yup. Gone through everything. Repaired and replaced wires and pins.

What does ring out mean? Go through the harness and rewire it?

No, I have it. Thank you though.

I believe it's an 83. It's been in the shop for 5 months now. I'm in Portland Oregon so there's that. I will be able to confirm with the shop on Monday.

Hi! I've been doing the field diagnostics and keep getting an unspecified code. Transmission was just rebuilt, shifts fine for a bit then goes back into limp mode. All solenoids and sensors have been replaced. Any help would be great!

Hi there, I haven't been on here for a bit. I had a transmission issue with my 4L80E, and it appears that water has gotten into it. Long story short, had it rebuilt and ready to install. I still cannot figure out how anything got into the transmission other than an issue with the...

I had a code 83 for the TCC which was a solenoid. Good idea on unplugging it. It's been a bit of a nightmare. Three weeks ago it ran through all gears, drove fine for about a mile then went back to limp mode and locking up the torque converter.

I apologize for the lack of updates. I replaced the TCC, clean fluid etc. It doesn't work. I have first and second gear kind of. It won't downshift from a stop. I drive it and first and second are great, but then at a stop sign it starts in second. Then starts doing the torque converter lockup...

I'll give that a shot. I'm wondering if I should replace every solenoid? There is a little fluid in the connector near the tail shaft on the driver's side. Apologies, I'm not a mechanic but learning more and more. Thanks again.

This is killing me haha. I switched the TCM, pulled codes and it indicated the TCC. I replaced it, and zero improvement. In fact it's acting even stranger. First into second is fine. When I slow down it stays in second. It will not shift into third, let alone fourth. After changing the solenoid...

Pulled the codes. I have an 83 (TCC) and an 85. Could the replacement of the TCM be an issue, and can it be reprogrammed? As of now I am planning on replacing the TCC, filter and fluids. Also, when I pull the output speed sensor there is a little fluid in there. Any input is appreciated

Not yet. Trying to juggle between work haha. Will do and let you know

Here is an update. After adding the transmission light and not being able to pull codes other than 12, swapped the TCM. The torque converter is not locking up anymore, and I have 1st and 2nd gears. The shift points are different. My truck is an 04 M1123. The donor TCM is an 07 M1123. Any ideas?

I did not. I was supposed to have the truck in a parade for a homecoming football game and it went south. Great advice though. I'll give it a shot when I get back into town. Does the TCM have to be year/model specific? I have access to a handful of TCMs but all different models and years.
