Just checking, I had a service place tell me there was no TC drain plug on a 2010 C300. True or False?

False. There is a TC drain plug. I just serviced my trans.

+1^ ~ It has a drain plug & they must drain it. The TC holds nearly 50% of the fluid charge. Many threads in this regard.

I figured that it did. I'm very handy around cars; this is my first MB, and was considering investing in the pump, dipstick tool, and thermometer for servicing myself, but tempted I'm to pay the dealer to do it, and have them give it a 39K checkup (It has 42K and 6 months on the factory warranty). Thought there might be a benefit to having dealer do it to cover any TSB/program changes that may have occurred since 2010...
Dealer wants $400 for just trans service, and $500 for full 39K Service.

Thoughts?

Going through the same issues now. Have a 2010 as well and the dealer keeps telling me they just do a flush b/c there is no drain. Ugh.
