4r70w only reverse!
 

So I'm getting codes for shift solenoid a and b but not at the same time and a few others (6) I have to see if I can get them back. At that point I could drive the truck but not get out of 1st gear. I shut the truck off for a few min. Came back and started backing up, I put it in drive, went to go again and nothing! There was a p0750, p1715, p1787? And a few about low circuit voltages? I know it's vague I'm sorry.
