My first and stock transmission kept kicking out of overdrive on its own, then didn't have overdrive. Changed fluid and filter out 3 times and it would work okay for a day or two then quit working. After a while it wouldn't go into gear or anything. I had two codes on light, TCC solenoid, and shift solenoid. Changed both of them worked fine for 4 days then transmission went completely out. Bought a used transmission, has a warranty and after changing transmission those same two codes popped up. After changing the transmission it only had third and second gear. I would have to manually shift from second to drive for me to have second and third. After changing both solenoids in drive I have first but wont shift out. I have first and second if manually shifted. Now I hear a whining noise sometimes coming from transmission and it wont shift into gear right away. I have to rev the truck up then it will violently shift into reverse. Don't know if the ECM is causing this because my truck will stall and has doing it for a while now. I have to wiggle the middle plug in order to start it back. Can my ECM be the culprit?

Let's start with what the actual codes are. Let me know the P codes and we can go from there.

I can make some guesses but the ECM may not be the cause because the ECM makes decisions on a few inputs. I am thinking it could be the transmission speed sensor but lets get the codes first and go from there.

Also, which transmission do you have? I assume it is the 44RE but let me know if it is the 46RE. Thanks

Good morning,

The first thing I would do is check to see if the cable is still attached at both the shifter at the bottom of the steering column and at the transmission.

If it is connected, then most likely the cable is broken and needs to be replaced.

I attached pictures and the procedure below for you to view.

The shift solenoids are in the transmission. You need to remove the trans pan to access them. This vehicle does not have a Transmission Control Module.
Transmission control is accomplished through the Engine Control Module or Powertrain Control Module.

My truck when put into drive does not go through one and second gear first. It’s stays in drive from start. If I manually switch gears they will all work. I have 2 obd2 codes 1. Shift solenoid a electrical. And 2. Torque converter clutch circuit electrical. So what do I need to do?

You will need a code reader or scan tool that will give you the actual numbers. There are so many codes for both issues.

A Parts store will read them for you for free.

Okay, The 743 is for the torque converter clutch solenoid circuit.

It could be the solenoid, wiring, valve body or a bad torque converter.

The flow chart is attached.

I will get the other code as well.

Okay, the 753 is for the shift solenoids.

The one thing they both have in common is the wiring harness. You need to check that harness very carefully for any damage.

Some of it and the rest is inside. You need to access the valve body by dropping the pan.

Okay, and can you show me a picture of what the torque converter clutch solenoid looks like for my car? I think I know but want to know for sure.
