MIL code U029D and U029E

[Larry Willard]

Yesterday after I changed the transmission fluid and filter I got code P2201,P0868 ,U029D, and U029E. I cleared all of them since I wanted to get rid of the P0868 which is low trans pressure that seems to happen when changing fluid and make sure all was well with that. The P2201 has been coming and going for over a year, those 2 didn't come back but the U029D and E are still present. Is there any way something connected with changing trans fluid had anything to do with these codes? A search turned up nothing concerning these. The EVIC also says service DEF system soon.

Took to dealer today, already had an appointment for the T05 recall. Stopped on the way and on restart I got a notice in the EVIC saying 180 miles to 5 MPH.
Guess I will have to wait and see what they find.

Neither of those codes have appeared at any time I have done sump filter changes. Must be some kind of coincidence.

Well it was as I thought, a coincidence. It was getting dark out and my wife says isn't it time to stop and finish tomorrow, and I said as soon as I put the crossmember up to hold the trans instead of the little bottle jack I had used. I stuck the bolts in and started the nuts and the following day hit them with the impact and never looked at anything else. Filled fluid and started it and got all the codes, and assumed I had knocked a wire loose but couldn't find it. Turns out that the wiring harness was pinched behind that bolt and I never noticed it, but tech found it after determining there was a blown fuse, they repaired it when doing the recall and all is now good. Guess I will always look for wiring harnesses in the future.
