Just to keep short and sweet! I bought this tahoe from a guy straight out a shop from getting transmission rebuilt now car won't move in any gear
Did you get a warranty? Call the shop first before sending it, but yes, you bought it in working condition, seems there is an issue there. I'd fight to have them make it right.
Check the fluid level first, if low fill to the full mark, if it is full then check the transfer case controls, make sure it is in 2WD and not neutral, you could also try 4WD high, if it all checks out mechanically then check the electrical connections. Is the check engine light on when the engine is running?
