Mercedes 722.9 7G-TRONIC Transmission Valve Body Disassembly Assembly part 11

what year did they start using the722.9?

nice

Can you please help me. Mercedes ml 320 cdi w164. Sometimes not turn up and not down. What is problem

There is 1 (one) missed steel ball in the picture shown in the video. There are a total of 13 steel balls, and the one missed is aprox. in the upper-right corner of the plate. In any case... a very good video.

I have a 2011 E350 with 7229 Transmission.
1)When shirting from reverse to drive at times it appears to go into drive then downshifts.
2) At times after going into drive and moving several feet another shift takes place.
Dealer can not get a DTC. This only occurs while in the "E" mode, at all temperatures.
Dealer states I/m not allowing enough time when going from brake to gas.
Are they any fault codes which would note a delay is NOT being allowed?
The value boy was changed out, the problem disappeared for several thousand miles, then came back. Another YT video takes about cleaning the solenoids. Your thoughts.

I found out there 14 steel check balls, they fix into the hole that you can see through, l got it thanks anyway.

How many steel check balls and where do they go ?
Thanks

why are you confusing everyone by saying that the bigger plate is the upper valve body? The bigger plate is the lower valve body. The smaller plate that attaches the plastic plate (on board computer) is the upper valve body. Look at the official diagram of 722.9 tranny.

Hi

We have an 05 SLK 350 7 speed auto transmission

Yesterday my wife was one her way to work pulled up at a set to a set of traffic lights went to pull off and suddenly wont shift out of 1st gear, managed to get it home some 2 miles in first. The car jerks hard from park to drive and reverse. So i put my Bluetooth adapter on it with the Carly for Mercedes diagnostic app and it gave these faults

I'm a member of several forums and all the guys n gals point to a damaged Transmission control unit (conductor plate)

After leaving the vehicle on the driveway nose facing up for a few days, i got in it to move it and it shifted into gear smoothly also the check engine light had gone

So i decided to do a transmission oil change hence removing the valve body in the procedure and following your video

Ive followed your video, but without taking the valve body apart, cleaned the solenoid screens, all solenoids measure a resistance of 5.2 ohms

So without taking up too much of your time i was trying to find out your thoughts

In advance Thank you

Great Video. Taking one out in a few days to have the conductor plate/control unit repaired.

thanks for you
