Although I doubt there would be any short-term problem, you should try to replace as much of the ATF as practical with the Pentosin CHF 7.1. My 530 has a drain plug at the pump which will drain about 700 ml out of the approx 1.5 l capacity. Top off with 7.1, drive, and drain 2 or 3 few times should provide sufficient dillution.
: My 91 525i uses chf 7.1 power steering fluid. About a year ago by mistake, I added ATF to reach the proper level. Have I contaminated the system? So far, nothing has gone wrong.
