How to trust Automatic Transmission (722.6)
Hey guys,
A little piece of advice, concerning the automatic transmission if you may. The post is a little long.
Here is the story:
I've bought my CLK200 Kompressor 02 in the last year. Made the trip (about 124 miles) and everything was fine. Smooth gear change, no clunks, strange sound, etc. The previous owner told me that he made the transmission service (fluid and filter).
During next weeks I've made about 250 more miles and everything stayed fine. Then, when I was making a trip in the highway, at a 80mph more or so, i decided to stop at the service station for a coffee. When i was slowing down, the car
start shaking with a horrible grinding sound from below and burnt smell. Massive transmission failure.
I've bought another trasmission and torque converter, both used, and asked my regular mechanic to fit them on the car. (He never worked with automatic transmissions before). He done the job fairly good, I must say. Then we put the fluid, swap filter, etc.
I guess It had to had more fluid, but he thought it was Ok.
Another 250 more miles and everything was good when.... When coming from another trip, near home, when slowing down, another damn grinding noise from below. AGAIN! Transmission bits and metal in the pan.
My conviction is that the transmission needed more fluid. I can remember in the highway, this time, that I thought the car was stuck in 4th, because the revs were high to the speed.
I've changed, again, with another transmission and torque! Changed also de radiator to a Behr and cleaned everything. My regular mechanic fit it all, we added the fluid.
After that, I took the car to the dealer to flush the system again, and change oil and filter again.
Everything looks smooth, soft gear change, etc. The question is that now I have a little fear of using the car in longer trips.
Was I just an unlucky *******, or should I fear that another problem is making my w209 blowing the transmissions? If so, what?
What can I do to trust my car again?
Thank you very much!

Sorry, I'm not enough of an expert to answer your question in any meaningful capacity other than advise to have a qualified mechanic look at the car. Even then, though, I feel like most mechanics (qualified or not) are often just guessing at what to real problem is and there has to be a bit of luck involved to truly fix the problem. I may be wrong, but this is my perception from reading and from conversing with others, etc.
It could be that one or more of the shift solenoids are not functioning properly, but I really have no idea. Here's a thread that may be of interest to you: https://mbworld.org/forums/c32-amg-c...-solved-8.html
Also, you may want to search the forums here (titles only) to see if you can find anyone with a similar issue as you.
Good luck- it's no fun having transmission issues!
