The transmission was very recently replaced in my SUV listed above. It drove fine for a couple of days. Then one day it just stopped driving forward while driving the vehicle was coasting. When pushing in the gas pedal the vehicle would remain coasting and the engine revs up without actually propelling the vehicle anywhere. I can turn the vehicle off for 1 minute then restart and am able to drive perfectly for a short distance before it happens again and again and again. Help!

The first thing we need to do is check the transmission fluid level and run the codes.

Here is a guide to help you with the codes:

I have seen the Valve Body Pressure Switch go bad and will cause this issue as well. Check out the images (below). Please let us know what happens.
