- Cummins diesel 6.7
Just spent 8500 on a new transmission for my 2014 3500 Cummins diesel 6.7L 120k miles. Drove out of the shop and check engine light on. Drove to AutoZone to get codes and it says P0870 OD hydraulic pressure test secondary all had to do with transmission. Have to wait until the morning to bring it back to the transmission shop, but wondering if anybody has had this problem or if knows why this could be happening? We’re supposed to be hauling a 17,000 pound fifth wheel tomorrow, and it’s making me a little nervous.
