It is a transmission related problem. It could be electrical, transmission or… nothing. The trans prog message cause the E34 to run in 3rd gear only, that is the reason wht you feel the car has no power. Check: 1) Turn the car off and wait 10min – 2) Main power relay, power to trans control module – 3) Gear selection switch – 4) Program switch (Manual or Auto) – 5) Computer box – 6) At last, the transmission.
