Mike0777 Posted May 1, 2019 Share Posted May 1, 2019 Hi everyone, I have a 2013 Ford Transit Connect that won't shift into 3rd gear. Just 1 month ago it was not shifting into 4th gear and had a check engine light. The mechanic connected the computer and said the code was p0172, "air fuel mixture too rich" and that may be the cause of the tranny acting up. I replaced the oxygen sensor, tranny oil and filter, spark plugs, fuel injectors, mass air flow sensor, and air filter. The TC drove great for 2 weeks. Than one day, all of a sudden, while driving on the highway the tranny started acting up again. Now instead of not shifting to 4th gear it wasn't shifting to 3rd and had a p0772 code "solenoid e stuck on" I had all solenoids changed but still not working right. It accelerates fine and it goes from 1st to 2nd beautifully then it slips and doesn't catch 3rd. Very frustrating, I don't know what else to do. Any advice would be greatly appreciated.

Unlockking Posted May 31, 2020 Share Posted May 31, 2020 Mike, please tell me you have found the root cause. I am in the same boat. I just recently changed replaced my transmission and everything you listed above including EGR. TC drove good for all of 20 minutes and 3 gears continue to be an issue.
