Thanks guys. I took it to a Indy trans shop that does work on bmws. They road tested it and said there is something wrong in the second drum. They also said they have fixed they 1-2 slam and will take care of it. My symptoms weren't strong today since it was warmer outside. I don't know if that tells me anything.

In the past year I have replaced valve gaskets, ccvs, plugs, battery, tail light, headlight bulbs, tires (only lasted 20k because of rear camber), termostat, water pump, and actuator gear. That's all I can think of just in this past year.
I still have a drivers seat with a hole on it from the seat heater wire burning through it. Have had that fixed as it will be another $400.
