So I am tracking down an electrical issue that may be PCM related. The transmission shop said it's electrical, but I feel like there are odd things that it does that leads me to think it's mechanical.
It was starting in second and third really badly, and it did not want to shift worth a dam. I replaced the vss on the back of the transmission, and it starts usually in 1st, shifting is allot better.
First issue is that when I turn on the OD off button nothing happens. The truck still runs and shifts like normal. It shifts into od and eve locks the converter.
It should drop out of oD and lock the converter, but it doesn't.
Next is I can downshift down to manual 2 even at 30 mph and nothing happens.
This leads me to it being a issue with the valve body.
Sometimes it still starts in second.
Now I just pulled into CVS, and went to put the truck in reverse and it hesitated, to go backwards for a second. It was weird.
It drove fine for a few tear drives, and then it started shifting back into 4th gear at 30 mph and locks the converter.
This has been driving me nuts. The shop said it is electrical, but the non working 1 or 2 selector.
