Did you ever get it fixed? If so what was the problem?.. a few days ago I was taking my daughter home and out of the blue my truck wouldn't move after I slowed down to make a turn my daughter house and when I went to press on the gas It wouldn't move and the needle stayed at 20mph, then all a sudden it moved like normal and I went a block, put it in park to let my daughter out . I put it in drive and it wouldn't move only reverse worke. So I drove it in reverse about 7 blocks to the nears gas station and then I lost reverse..so I had it towed and the next morning I started it and it had reverse again and drive a little bit..I had code P2106 come up and P0720...no burnt trans fluid or  Is grinding noise..I'm lost right now because $$$ wise I don't have it like that. So me just getting parts in hopes that it will work isn't an option right now..but what I read about yours sounds just like mine
