Hi all

I have a 2002 X5 4.4. I get the 'trans failsafe prog', first time the car is started and the car appears to be stuck in 3rd gear. When I switch the car off and then on again the car usually works fine for the rest of the day.

When I used the 'autologic' diagnostic system, the transmission module gave the following error p0700 and p1734: - Pressure Control Solenoid "2" Electrical.

Guessing it was a problem with one of the valves in the valve body, we opened the valve body and swapped the valves but the next morning we got the same Pressure Control Solenoid "2" Electrical. We've checked the wiring and nothing seems to be obvious wrong.

I read the following:-

Interestingly my car also showed a very high temperature reading a few times, however when we disconnected and reconnected the wiring loom to the ECU, the temp reading fixed itself.

Warm regards
