Since we cannot comment on the estimation for the proffesional work the fact is that spares of Mercedes-Benz is expensive.The leak has to be plugged,the transmission system has to be overalled and possible damaged parts replaced.What could be suggested to have it open for overalling,clean the system and reassemble with newtransmission fluid.May be a freelancer can do it.

8,000$ sounds a bit too much but the parts are really expensive. didnt they explain how did the coolent get in to the trans. it could be a leaking cooling coil of the trans located in side the raditor that for sure needs to be replaced but u can try by flushing out the trans fluid but the process has to be repeated three or more times. the trans is in a running state???? or did it stall... do quote more. !!!!

    It seems the problem with this car is the torque converter. MB sticks by its claim with transmission fluid has leaked, but an independent transmission owner has stated that showed my husband there is no contamination to the control module. Who do you believe? I also have a 2003 C240 that had to have a transmission replaced, but it was under warranty. what is the problem with the Mercedes transmissions??

There is no componet that can be repaired

My truck is leaking anti-freeze between the engine block and transmission bell housing. Anti-freeze leaks onto the crossover exhaust pipe. Any ideas on how to fix this cheaply?

There is a freeze plug back there that must have came out. The plug is cheap, but you have to take the transmission off to get to it.

I have a 2004 Monte Carlo SS, while driving I lost all water and it over heated. turns out the frost plug at the front of the motor (block heater one) had blown out. I never saw any leaks on the ground...

your main concern right now is to replace the frost plug and while you are at it flush the engine then fill with proper anti freeze mix, you should be good to go

What does it mean when transfluid get into the coolant

The transmission has cooler lines that run to and from the radiator. The fluid is cooled, by running thru tubing inside the one side of the radiator tank. The tubing probably has a leak, causing anti-freeze to get into the transmission. This MUST be repaired, due to the fact that the anti-freeze will do some damage to the transmission.
