Option 1 (Mercedes) said that they will only replace any broken parts they find when the open the transmission and clean and test the rest and change some soft parts. That's all they would tell me.

Option 2 (Aftermarket) said that they replace seals, clutches, bands and some other parts that I can't remember the names of. All hard parts are checked to meet standards and then dyno tested. They actually prefer the car to be there to do the testing and final adjustments.

What I need is a check list of what should be replaced and checked on a transmission rebuild and compare that to what they offer. If anyone can provide one, it would be realy appreciate it. I'm very unfamiliar with automatic transmission inner workings.

Thank You
