I have a 2003 530i. What is a normal operating rpm at 70 mph? Also..... I have a ses light with a code 0741, torque converter lock up. It shifts fine and drives fine. Is higher rpm at highway speeds the only problem I will have? Ok to drive with this code?
All depends on tire size, wheel size, and gear ratio's in the drivetrain. If someone has the identical car as yours and taller tires, they will be running a lower RPM at 70mph.

It depends on the gear ratios in the drivetrain. As stated in your other thread driving around with a problem like that can cause other problems. If your RPM is higher because the torque converter is "slipping" the entire time you are at highway speeds I'd expect problems.
