Having a problem with my Z4 that I can’t narrow down.
When the engine is cold/warming up it runs, and shifts, beautifully. Once the engine is warmed up, especially if it’s hot outside, the transmission begins shifting erratically and goes into limp mode. Only code it throws is P0700. It’s had some small electrical issues, but always reads proper voltage, and always starts right up. It only slips from 3rd gear up. I’ve replaced the trans fluid and filter, I’m not sure if I should be going electrical, or mechanical. I’m looking into replacing the TCM but it’s difficult to find. Any thoughts?
