Transmission goes out of gear after a few minutes

I think it's on it's way out unless the filter is clogged ,, fluid should be at correct level and nice and pink , you can take it to a shop but I think it's done

It hasnt been long since it was rebuilt. And everytime I turn it off and restart it the transmission works fine for a few minutes.

Better use your warranty!!!

Warranty is out. If it had warranty I wouldnt be asking for help.

My 04 Yukon is doing the same thing. Did you ever figure out the problem?

I’m having the same exact issue to date. Anyone ever figure out what it was ?

My dad took off and inspected the solenoids (I think that is what it was) and it worked for a few weeks. I was so excited because I hadn't driven it in a year because we couldn't figure out the issue. I finally decided it was safe to drive out of town, but I was wrong. It started doing the same thing again on my way back home. I had to turn it off and back on several times to get closer to home. I eventually called my dad and he had to tow it home. Now we are back to square one. I feel like it has to be electrical and not the actual transmission through. Because I can't see it working off and on if the transmission was going out.
