Well, got a call from the transmission shop just an hour ago 
Unfortunately didn't give me good news, he wants to charge $1395 to drop the transmission and somewhere around $5500 to $6500 to get the transmission fixed.
I asked him why can't I just buy a used transmission and replace it, He said he doesn't do that, he wants to fully rebuild the transmission as that is what he has been doing for 42 years.
Does this sound ok to all you guys? I mean i was hoping that it was only the conductor plate and solenoids that needed to be replaced, I was estimating I would only have to spend around $3500 at the most, but Yikes!!!!
From doing a lot of research I have read in many threads that it is totally possible to program a new TCM to a different car, This guy told me he would need to take the transmission to the dealer after rebuilding the entire thing, but that doesn't make sense to me unless he replaces the TCM as well.
If that is the case, why wouldn't you be able to entirely replace the whole transmission if you still have to reprogram the TCM?
I mean wouldn't it be the same, if He still needs to take the rebuilt transmission to the dealer to get it programmed, why not do the same with a used transmission?
What do you guys think, am I missing something or does all this make sense to you?
Looks to me that I am totally screwed either way.

What are your options? Pay the money, or take the car to another repair shop. Call first to find a repair shop that will fix the transmission according to your wishes. Or buy a new vehicle.

2013 Mercedes Benz C250
2013 Mercedes Benz C250 mechanic said faulty electronic plate
hey new to the forums just need some help,
Purchased my car brand new from dealer ship 2013 Mercedes Benz c250 currently on 55,000KMS hardly drive anywhere.
Few months now I have been driving it has a sudden jerking feeling like a tug pull, goes into limp mode , check engine light comes up. I pull over and the car dosen't start up again
maybe after 20-30 mins it will start. check engine light sometimes comes on and goes away. Thought it had something to do with the petrol, dirty fuel etc but wasnt the case.
took it to the mechanics and they said it has a faulty electronic plate . wondering if anyone else has had this problem because i think they going to charge me an arm and leg.

Update: Two years on, the car is running great
Just a follow up to point out we have now put over 25,000 miles on the car since I dropped the TCU and had it repaired, and the car is still humming along beautifully.
I say this only to encourage other people not to throw in the towel if they have a malfunctioning sensor or solenoid. It is absolutely worth the repair!

Mercedes CL550
I had this minimal leak of radiator fluid that was easily topped off. I was seeing it leaking near the AC compressor \ tray. My transmission was initially shuddering. I didn't know its was transmission. Thinking it was an abs, flat tire or air shock issue. Felt like i was driving on cobblestone road. After stopping & checking everything. I started car & drove normally.
Not knowing it was the transmission & how serious it was. Now my 2013 Mercedes cl550 isn't shifting. Its Slipping. Some movement in reverse. You believe trans overheated? I happened to neglect 70k blue ATF service replacement.
What would u do first? I believe my transmission cooler is a separate small radiator sandwiched in between fan, radiator, secondary\aux turbo radiator & ac condenser. I wish i knew the word "shudder" i definitely wouldn't have driven car an inch after that.
Thankfull in advance.
