Hi there,
About a week ago I got a message saying "Transmission Service Required". So I changed the Transmission fluid and filter and there was no significant debris. When I took my B200 to the road, it was normal at first however after 10 minutes, I got that earlier message again, and also my shifting was no longer normal and the RPM's would fluctuate a lot. Would anyone now how I can fix this?
Thanks in advance

BenzDreams,
Don't get too discouraged with the above posts. It will cost you money, but may not even be close to what was quoted above. It all depends on the issue. If it is an actual problem with the CVT, then it may be costly. But if it a problem with the TCU in the Valve Body of the Transmission, then it can be repaired. In majority of the transmission issues it has been the latter. MB refuses to repair this issue and usually errs on the side of replacing the valve body or entire transmission. This is where the huge bill comes from. If you find a mechanic who is experienced with removing and repairing this. This can be done at a fraction of the cost. Very few mechanics are versed in this repair. There is a guy in Bulgaria who can do it, and he has dropped many messages on this forum. If you get a reputable and knowledgable transmission or MB mechanic to pull the VB and mail it to Bulgaria, he will repair and mail it back for install. This will cost around $600 plus mechanic labour, and possibly delivery. That is of course, if this is your problem. It is an electrical problem that has affected a number of transmissions. Your first step is to find out what type of issue you have. Good Luck.

Hi. All included it cost me $800 to repair it in a transmission specialist shop. Including tx and oil and filter at the same time.
At Laval auto transmission
He remove the part inside and had it rebuild. So there is no need to change the entire transmission or PCU.
I got a 2 years warranty.
Very satisfied.
He also repaired my 2008 Lincoln MKX transmission three years ago for $650.

You're welcome. I brought tje car in the morning and got it back at theend of next day. It's always expensive a transmission job. Bit I really think he is fair and he has great reviews. So I'm satisfied. He's not trying to screw us by changing parts that are not necessary. 👍👍👍

When I had TCU failure (Power loss, Transmission failure and take it to the shop message) I took it to Mister Transmission | Transmission and Technology Experts shop. It works well since. Took about a week cause they sent the TCU somewhere to rebuild. It cost me 2000CAD to fix ii in North Vancouver.
So you can check with them (they are chain so have shops in Alberta too).

Edit: I just wanted to say that they also did transmission oil and filter change as they are opening it up anyway. So that goes into the price.

It has been awhile since Chassy posted. Perhaps this place in Dorval could be an option for you:

Thank you gor referring Norwestcan my daughter's B200 transmission was making noises. She took it to a transmission shop who said it needed to be replaced. Over 3k for a used transmission. Not worth the money. She kept driving it and it got worse. Luckily I found his post and she took it to Victoria at Norwestcan. It was low on tranny fluid. That's it. How a transmission shop could tell us that is mind blowing. Honest and skilled. Top marks to Norwestcan
