No Acceleration

Hello,
I'm new here. I wanted to know if anyone can help me figure out my truck issue.
No check engine light, yet my truck will not accelerate when pressing the gas pedal. I can hear the engine rev and truck will not move.
no codes, check codes with MB II icarsoft tool. only message on dash is brake wear.

Did the acceleration problem occur at the same time the message on dash is brake wear came on? If so, this is a safety measure telling you to replace the warn pads and you will get your acceleration back.

Hello,
Maj. Dundee
The light was on for a while, the truck turned off while driving. Pulled over and it started back up yet couldn't pull off, no acceleration.
Towed home now, no check engine light and no codes. I will take a look at the brakes.

You really didn't answer my question, but there has to be a code stored for this problem.

Do you have a scanner reader? If you do, check for codes in all modules.

Maybe Differential is broken.? Focus on it. I had the same problem before.

Hello, everyone I do apologize I had to take care of a family member, and put the truck aside.
SO far the truck is still sitting in the same position, haven't found what could be the issue.
I did find that the brake light as do to the brake wear sensor was missing the metal insert, it wasn't able to read. I replaced the sensor and the warning light went out.
Was under the truck while my daughter pressed the gas pedal and the drive shaft from the front diff to the torque converter, turned and quickly turned back, did not complete a full 360.

Hello,

In my vehicle, the vehicle is rolling over, but not moving.

the part of the differential I showed below was locked/broken so Cardan Shaft didn't turn it also locked. before this part broke, car kicks when slowing down.



red part is broken.

Do any of you know what these wires go to?
