i swapped out fluid with Mobil 1 ATF(..multivehicle) twice...i see some imrpovement but i still hear it though ...will do the flush


QUOTE=racingbmwm3;940427]Dexron III is ATF and is what is recommended. I've mixed brands and types of ATF in other cars PS systems before without any noise problems though. (Dexron 3, 4, Dexron/Mercon)

If the fluid isn't low, then an actual flush of ATF through the system would be the next step. Perhaps some dirt/debris got into the system during the repair?[/QUOTE]
