Wiring diagrams for transmission and the TCM control module?

My truck will not shift into third and when it does the truck will not go. I cannot find the fuse for the transmission.

I put a 1993 4l80e transmission in this truck in place of a 4l60e got the transmission plug required into the harness, but I cannot find any where if the PCM I have is able to run this transmission. I do also have the PROM out of the PCM this transmission was used with is there any other wires that need to be put in place to operate this transmission properly? The PCM have is 16296395 with the red and blue connectors 32 pin I have the DRAC also.

The plug on the left is what I have spliced into the harness of the plug on the far right minus pin u which is where a brown wire is supposed to be according to most wiring diagrams but mine didn’t have one there. I added the front speed sensor in on pin F-2 and F-3 and with the wiring on the plug the TCC should be wired in at E-10 on the PCM.

In need of TCM wiring diagram for 2012 Silverado 1500 4.8L 4x4 4l60e

I have a GM Supermatic TCM from a 2013 4L65E. I'm wondering how to just test to see if it's completely bad before I spend the $1,000.00 on a new one. Can anyone help me out with that? My truck (LS3 Connect and Cruise package swap) is stuck in 1st gear. I have reverse and neutral. But will not shift out of 1st. Drives the exact same if I unplug the TCM, or keep it plugged in. It's like it's not communicating or something. I just want to know if there's an easy way to test it with a multimeter.

Hey thanks for the help! The last time I got any codes from it was a P0700, which I believe is the TCM. The scanner I use only gave me that generic code, wasn't able to get anything more than that. This happened pretty much the day after I did the Connect and Cruise swap. Chevy wasn't much help and said just erase the code. So that's what I've been doing every once in a while when the check light comes on. Its always been that same code. It would put it into limp mode until I erased it, then it was fine after that. But now, it's just locked into 1st gear.

This 1st gear problem began after a long hot trip through Vegas and back. When I got back it started shifting to 2nd at a much higher RPM than normal, so it was a noticeable problem. But the fact that it always shifted at around 3,000 RPM rather than 2,500 tells me it was a computer issue. I'm not sure. But it was still drivable. 2nd to 3rd was fine, and so on. Only 1st to 2nd was problematic. Just was not able to go anywhere near WOT. If I gave it some aggressive throttle, it would act like the clutch was slipping. (Rev super high, not shift). The other night driving home, it finally just stopped shifting all together. And now I am stuck in first.

I appreciate your help!

Okay so I borrowed my neighbors LaunchTech OBD2 touchscreen scanner and was able to get live data as far as transmission fluid temperatures, and shift solenoids so at least I know the TCM is talking, I think? It gave connection errors when attempting to run tests with the TCM unplugged, so it knows it's there.

The only data I could read on the solenoids was:
Truck in park, Shift 1-2 Solenoid: On. Shift 2-3 Solenoid: Off. Downshift 3-2 Solenoid: On.
Truck in Drive, All solenoids: ON.

I have zero idea what the readings are supposed to be for each solenoid when in park/drive.

The scanner gave no DTC codes. It said all was fine. But probably because I cleared the codes a while ago and it hasn't come back on.

That's what I'm thinking too. I also ordered a bi-directional OBD2 tool so I can test the solenoid actuators and see if they are all functioning this weekend.

The truck is a 1964 Chevy C10, but the powertrain is a GM Performance LS3 Connect and Cruise package. Basically a 2013 Camaro SS 6.2L V8 with 4L65E trans. It wasn't out of a donor vehicle; it was a crate motor/trans package bought brand new.

I've been having difficulties with the parts store and google. My 2011 4.8 4x4 pulled the p0717 and I've tried getting a new TSS, but the parts store gave me the wrong one for my truck, and forums are saying it's on the top of the transmission, but I can't feel or see any on the top. The closest I've gotten to an answer has been on the rear of the transfer case. Is this the correct location.

Also, I'm going to be checking the grounds and tracing the wiring, do you have the diagram I'm needing?

Thank you!

So, I just replaced my transmission on my 2008 Chevrolet Silverado 1500 5.3L. I had a p0717 code before I replaced it, and I bought a new transmission, so it came with a new ISS. But I’m still having the code pop up. I went to the dealership to get the transmission programmed, and the engine light came back on. I called back up there and they said it can’t be anything with the TCM because it wouldn’t let them program it. We hooked up our scanner, and looked at the freeze frames, and we figured out that the input, 0 until we shift out of first gear and then everything is fine. I’m confused on where to go from here. We checked the voltage on the ISS sign wire, and the low reference wire, and when I put it in gear the ISS sign wire is grounded. I’m not sure if that’s correct or not. Please get back to me as soon as possible. Thank you!
