Transmission issues

[whitedragon551]

Finally got all the parts replaced on my SUV. Only thing that's left is to get it up to speed.

I swapped throttle position sensors under warranty and took it for a test drive. I still wasn't able to get it up to speed. I parked it and put it in neutral and swapped from rear wheel to 4 wheel. I couldn't accelerate past 10mph. I parked again to swap back and upon swapping back the indicator lights near the speedometer started flashing high lo. Only way I could get it to stop was to move the switch on the dash from 2wd to lock or shut the truck off and restart it.

Here is a quick video I took. At the end is where I move the switch to lock.

What would cause this issue?

Are the transmission fluid and transfer case fluid levels correct? How is the condition of both fluids?

You can try the TCM self-diagnosis procedure described on page AT-44 to see if that will yield any insight. I can't look at your video right now, sorry.

I really don't know too much about the workings of the 4WD systems and how to troubleshoot them, so hopefully someone else may have a better idea.

Took it to the shop for a free estimate where I know the owner. Definitely a transmission issue. Everything is reporting correctly with sensors so he doesnt know what it is unless you takes it out and rips it apart.

Vehicle is going to the scrap yard.
