I have an 2002 E39 530i automatic. I love this car, but it is giving me some problems and any help, suggestions or advice will be highly appreciated. This is my issue with the E39, sometimes when you start the car it indicates " TRANS. FAILSAFE PROG" on the dash and also when this is displayed , the gear lever position is Not displayed and the car would pull very poorly as if it is on 3rd gear. Sometimes when you shift from D to either R or P, then also you would get the same fault displayed on the dash. But if you switch off the engine and after a couple of restarts the fault would clear and the car would drive fine as long as you do not move the gear lever to any other position. I have changed the gearbox oil and the filter, which helped in having the fault less frequently, but if you do not use the car for a few day, then the fault is more frequent. Any advice on the above matter is highly appreciated.
