Dear sifus,Need advise on my car e60 530i 05 model, yeasterday i had 2 experiance, its never happen before, during drive back from kampong, 7 hours drive, thru labuh raya Timur Barat in very heavy rain, its accoured while i slam the pedal around 7600 rpm to overtake the trailler than 'transmmission error' comeout, than it run in control mode maybe in 3rd gear, so i stop the car and shut off the engine, than on again, its back to normal, its accured againduring overtake sirocco, 4 hour after first error...Slam pedal, than it repeat again. Stop and on again, back to normal...my curious is, issit my GB in really faulty or just the glich code. I'm thingking may be also due to wet condition on the sensor since almost one week my car in flooding wet condition...hopefully not big issue later, today its like back to normal, anyway will send to my mech for detail inspection...some advise pls
