Transmission problem
1998 BMW 740 V8 Two Wheel Drive Automatic 11600 miles
----------------------------------------------------------------
Hi. I have a BMW 740iL that has a Trans Fail Safe Mode error message. I had it checked with the OBD tester and it gave me 4 errors. P0720, P0731, P0732, P0734. These are Output Speed Sensor Circuit Malfunction and Gear 1, 2, 4 Ratio Incorrect. Do you know what this may mean? The car does run and moves, but it does not take off very well at all in drive. Once you get up to 35-45 MPH it runs fine. It also goes into reverse fine. Please let me know what you think. Thank you for all of your help. --Alton

I recommend seeking local professional help. this is a speed sensor issue and will require removal of the oil pan on the transmission
