My buddy was pulling into his driveway and his truck went into 2nd, the service stabiltrak, service traction control, and parking assist lights all came on. The truck won’t go out of 2nd. It’s a 2012 with 142k miles, a cold air ram intake, and exhaust are the only modes besides leveling kit and shackles. Both intake and exhaust have been on since new. He’s not sure what to do so I told him I’d post here because I figured someone here has experienced this. The current status is:

Here’s what is wrong that I’ve noticed:
* U0101 code comes up.
*dash says service stabiltrak, service traction control and parking assist off.
*It doesn't shift pass 2nd gear
*When I put it into park the doors don't unlock.
- It's like the computer doesn't know what the transmission is doing.

Any help would be greatly appreciated! 🙏🏻
