Hi Guys, I drive a 735il 1992, After a morning startup and moving off I get a massive SLAP whilst changing from 1st to 2nd gear. This is immediatly followed by a computer message "TRANS PROGRAM" and then after a traffic light stop or similar, there appears to be no drive power at take off, It gets back to a normal feel after achieving about 60Klm or 35mph. when the engine is hot and I stop for a while then restart it gives No Problem until next day.Hoping someone can shed light on the problem.Kindest regards,PERRIN
