The other day my truck was acting like its in neutral at a stop light so i took it home and diagnosed it as a bad nsbu. Changed it out today and cleared the codes. Got alittle ways from my driveway and what do you know nothing has changed. Pulled it back to the garage and it started flashing the PRND321 again. Not sure what else it could be, all wires looked good on plugs and both clicked in. Cant have the truck down as i drive it everyday, had the codes P0700 and P0747 (pretty sure that was the other one). Went out there and plugged my v2 into it and now theres no dtcs and the truck doesnt move in any selection. Needs advice and ideas asap.
