I have a 2002 Passat GLS 4Motion with 121,000 miles on it. I bought it at 77,000 miles and have not done anything with the transmission. I don't know if anything has ever been done on it (including changing the ATF).
Occasionally when I let off the accelerator and then accelerate again, the transmission seems to thump/kick. I figure I need a transmission drain (not a flush?). The dealership told me to do a flush for $325. If that didn't fix it, they may need to change the motor mount for $225.
I independent guy who works on VW's and other foreign cars said not to do a flush but just a drain. He said it will take two hours at $75 per hour plus the filter and ATF.
Repairpal estimates the ATF change to cost about $150. Who to believe? How much should a drain cost? Is a drain safer than a flush?
