I still have an unresolved issue with my transmission. No gears are engaging. The common fault is the conductor plate valve body after changing the floor shifter. I looked at the U tube video and conclude that as long as the bolts holding the oil pan on come off without a fight then the job is doable for a beginner.
I am concerned that the shifter and conductor plate needed to be changed at the same time. without the 13 pin plug not leaking as expected. I'm going to drain the transmission oil and see if the pan can be removed without braking parts.
Any advice would be welcome.


It's not a difficult job that's for sure. Please make sure you get the car up and secure it with jack stands. You will need about 5 quarts of transmission fluid. I would say stick to the OEM trans fluid. If you have the right tools you will be able to finish in about 2 to 3 hours.

Good luck and make sure to take some pictures. Maybe you can write a DIY and post it here. I am sure it will help others. Also we can help you better if something comes up.

Hi Fanatic,
Spent 4 hours under the car today. Everything went well except no change, still wont go into gear.
Carsoft was showing 0704 error I cleared that and tried to shift without success.
shifter is connected, I'm thinking that the gear shift in the valve body went in correctly. what is next on the list.
The solenoids looked unmarked, and the oil seemed dirty but no signs of iron fillings, there was a small magnet in the oil pan that was clean.

I see from a previous post that you recommend a different diagnostic tool for resetting the system with a 38 pin fitting. I've waited 2 weeks trying to get the gears to work so 2 another couple of days is ok. if I ask an engineer to come out to me, as the car cannot move, it's going to be $200. So I might just as well invest in the tools.

Hi Ray,
I ordered this "Hain@ Mercedes Benz Carsoft 7.4 Brand New MB Carsoft 7.4 Multiplexer " that says it requires a laptop to read the softwear.
Do you know if the cable might work in the Carsoft MB II that I already have are they compatible ?
My concern is that the multiplexer may carry malwear / virus. it doesn't get very high ratings as a product.
