Driving near home about 30 mph a big Blow/Thump noise then constant grinding noise five minutes to home, next put gear in reverse nothing moved but forward GMC moves OK. Everything else looks OK. Cannot back-up turn Yukon still moves forward but noisy. Transmission slip gear my guess!

Have it towed to a local transmission shop.

I’d start getting ready to buy a new/rebuilt transmission myself. Good luck.

yes, it does sounds like you’re going to need to rebuild the transmission or get a new one [Dianabol review](https://pharmacomlabs.to/dianabol-review/).  
what’s car mileage?

If you have 4WD it could be the transfer case…
