Codes. Truck won’t move

[denata]

Solenoid B connected?

 

[denata]

Press any key please.and read errors again

Solenoid B connected

I clear the codes Then they come back

The pause between turning the ignition on and off must be at least 40 seconds.

This comes back right away. Not even able to cycle the key But no solenoid B now

This is getting me frustrated lol

When you measured the voltage at solenoid A, it was about 4 volts. but it should be about 7 volts. Are you sure that the TCM is 100% functional?

This TCM that’s hooked up now come out of his running truck until the motor blew


The original TCM from my truck was doing the same thing with codes as his

Are the connector contacts to the gearbox oxidized?

 

[denata]

Can you insert the probes into the solenoid A connector, turn on the ignition and move the all wiring harness and connectors, and observe the multimeter readings?

Internal. Harness. Brand new

External plug looks okay

Not sure how to upload the video

These pics are all from just moving the external plug.

I here clicking when moving the external plug around aswell

When not moving the external harness it holds at 4.6

Not sure how to upload the video

upload to youtube then post the link to it here.

I feel like you have some loose contacts in the plug, ether on the truck harness side or on the trans side. moving it around and seeing a fluctuation from 4 to 6 up to 11 volts

Denta is the more knowledgeable person here, but I wonder if the internal harness that was installed might be of the chineesium variety. I'm curious if there would be a way to just slightly tighten up the contacts in the connector and try measuring again. if not, it's possibly gonna be firing the parts cannon at a new internal harness or the main harness pigtail connector or possibly both!

Internal harness is new.

External is original to the truck by the looks of it

Can you post a better photo of the connector ends? I'm looking at the harness side and from the photo, it actually looks like three of the pins were replaced at some point. they look different than the rest.

on the trans side, I can't really make much out as it's dark. maybe try turning on your flash for the camera.

I really feel like there might be an issue in this connector with your voltage changing. I assume your were moving this connector with the meter on the solenoid.

Will have to get a better picture when it stops raining now


Internal harness was a OEM replacement

 

[dbrannon79]

the solenoid you are probing for voltage, you can also probe that same wire in the truck harness connector and see if you have something different. but I would wait till @denata is back with further instruction.
