Mechatronic problem

Dealer just finished replacing water pump, thermostat, and coolant expansion tank. While they were servicing, they also recommend replacing mechatronics sleeve and transmission pan gasket due to transmission fluid leak. I have search the forum and it seems that this is a common problem with e90 auto. I haven't notice any fluid leaks when parked overnight. Want to know how urgent should I have this done and what's a reasonable cost to do it (dealer or independent). Is this a DIY that is difficult and easy to screw things up big time? Any input is greatly appreciated. BTW, my car is a 08 335xi with 117k miles. TIA.
