Rich,
Funny you asked about this... I need to change my fluid and a few friends want to change their trans fluid. I asked Marc his opinion and go this.
"We no longer use the BMW lubricant because new products are available
that are better.
For a street driven car with the OE dual mass flywheel we use Amsoil
MTF. It's a 5W-30 synthetic lubricant. It's better than the GM lube
that has been discontinued because the GM lube used mineral oil. You
can get it from me or any Amsoil dealer.
For a car with a dual mass flywheel we use Red Line Shock Proof
Heavy. It quiets the transmission better than the BMW 10W-60. It is
also good for racing because it is synthetic. You can get it from
Summit Racing. RED-58204"
Ordered Red Line!
