When driving a little and I let off the accelerator it won’t go anymore. The engine just revs up and I was able to pull over and shut it off and turn back on and then it would go into gear. Then it stopped doing that and only way I was able to move is if I put it into 4 high and then it stopped working in 4 high. So I got pulled home and when I got back in driveway I tried to put it into drive or reverse and it would go into both.

Sounds like the pump in the transmission failed. We need to start with checking the fluid and make sure it is full and not burned. If it is then we need to replace the fluid and top it off.

If the pump has no fluid to pressurize then it will not engage any gears and the RPM will just rev up.

Below you will find the info on the pump which is what I suspect this is.

If the fluid is ok then we need to check for codes and then check the pressure in the unit. However, that is not the easiest process so let's start with checking this material and go from there.

Thanks
