Today I went to the store and my truck did a hard shift from first into second as I was pulling away from my house.
- Drove to the store without further issue.
- Parked and was inside for about 10 minutes.
- Attempted a remote start while inside the store, even though the truck was locked it didn't start.
- Started truck from inside the cab and began the drive back home.
- Had another hard shift from first into second coming out of the parking lot. Wife commented on it. But we were coming to a stop.
- Light changed, hard shift from first into second. So I applied gentler throttle, figuring it was my fault or something.
- Then got a very hard shift from 3rd into 4th and completely lost throttle for about two or three seconds.
- I gave it some more throttle as I was coasting in traffic and the gas pedal went to the floor. When I say to the floor, it felt like there was zero resistance in the pedal and my foot went completely to the floor.
- Turbo was completely dead. Throttle barely moved the truck. No engine feedback.
- Coasted to the next stop and turned off the truck at the light, restarted the truck.
- Truck started back up without issue, gas pedal reengaged, it didn't hard shift again from first into second.
- Turned into my neighborhood and the truck drove normally for the rest of the drive home. It was fine at the four way stop near my house and again at the three way stop on my corner.
It's parked in the driveway now and I'm contemplating what to do. It didn't throw any indicators the entire drive, and it was literally a 15 minute round trip. So, I'm pretty sure that without codes, the service department isn't going to know how to diagnose this issue. Also pretty sure if I keep driving it, the transmission is going to fail at some point.
It was particularly bothersome that I lost throttle at 45 mph and I was pretty lucky I was able to coast into the turn lane to restart my truck.
On the phone, on hold with my service department while typing this. Gonna see what they recommend.
Truck has less than 1200 on the ODO.
UPDATE:
Dealership was able to do an OTA diagnosis on it.
Basically read off everything I stated and had exact timestamps and mileage for the events.
The truck threw the code B277A96 when I attempted to remote start it.
The code cleared after I turned the truck off and turned it back on after the hard shift and throttle events and now the truck isn't showing any codes at all.
Incidentally, that's when it started acting normal again.
Edit: Taking it to the dealership on Monday morning (if it drives). Hopefully it's something simple to fix and not an actual drivetrain issue.
