I have a 1988 735i with the E32 engine and automatic transmission. Tonight the car would thump quite markedly when changing from 1st to 2nd gear. While stuck in stop and go traffic the car would not advance while in D - drive. It would go OK if I put it in position 3 of the gear shift. It also started smoking a lot, but there was no visible leak when I parked the car. I had to drive about 20 miles in 3 at about 60 mph and did not have any problems. The D position still does not work, the tachometer revolutions goes up but the car does not advance.
I have trouble reading the level on the transmission dip stick. It is difficult to see the liquid on the stick. However when I took it to the dealer sometime ago, he said that the level was OK. Does anyone know of a trick to read this level?
Any help will be appreciated.
