Will have to consider the BT tool. This is my wife's daily car, and she loves it. She's worried BMW will stop bringing the wagons over, when she's ready for a new one in ~5 years.
I'll get an allen wrench and attempt the TC fluid job. Funny, the dealer quote was reasonable, except they quoted 2L of fluid at $55 per liter (it only holds less than 1L) and the labor was $75. Cheaper than the BT tool right now....
What did you think of my drain & fill idea for the tranny?
