Not having tools or a place to do maintenance can make the process described here costly. I had mine serviced at 86K and it was just shy of $400 and that was at an indy. Doing it 3-4X would be cheaper than a new trans but it's still a chunk of change. I had always heard there was a pressure unit that flushed the fluid out but it sounds like that was an internet myth. It's disappointing that Porsche doesn't have a tool to flush the trans and would leave it to having the customer pay for 3-4 changes just to get new fluid. I thought AAMCO had a pressurized system to drain auto trans's.
