Photo DIY- 722.6 Conductor Plate and Pressure Regulator Spring R/R

A well know problem to us all.... Failure of the "Electronics Pack/Conductor Plate"....

With 2 other MB with the 722.6 box, I've "always" noticed a "Difference" in the way the E320 shifted.. Even straight out of the Sindelfingen plant... "A different thrust/weight ratio??".. who knows...

Well the Human self-defense mechanism of "Denial" is quite strong.... After having a progressively more "noticeable" shifting between 1->2, and 2->3.... "Well, I'll reset the computer".... It is slightly better for "awhile"... then Yuck. "Well I say (again) to myself.... OhLord *DID* say the new 722.9 fluid causes a harsher shift...""

My bubble of Denial burst the other day... Going to work... at a stop sign, hit the gas... VVRROOMMM... but am NOT MOVING!! Ok, let's try reverse... VVROOOMMM

Oh.... Sh.....ugar!! A $5,000 trany needed!!

After a "reset" I get home, and hook my Baby up to my new "toy" STAR Compact3.

Since I have the diagnostic skill of a Temple Monkey... I use my "Mechanic in a Laptop" to take my hand and guide me down the diagnostic tree to determine my "Speed Sensor #3" is "Intermittently" failing.. So, I'll change it out.

Thus, the post.

Here is a list of needed Parts:

8 quarts of the "new" MB fluid 001-989-68-03-10
Filter 140-277-00-95
Pan Gasket 140-271-00-80
Lock Clip 140-991-00-55
Trans Pan Drain Washer 140-271-00-60
Torque Converter Washer N 007603010100
Conductor Plate/"Electronics Pack" 140-270-11-61
"Updated" Connector Bushing 203-540-02-53
Pressure Regulator Spring (Yes, those Idiots at MB change out the WHOLE Valve body, rather than the stupid $8 spring-- thus, NO MB number) Sonnax 68942-01 You should be able to get it at your local Transmission Supply house.

Like the WIS warns.. "Even a Speck of Foreign Material can Cause **FAILURE** of the Transmission"---- So BE WARNED!! Absolutely METICULOUS Cleanliness must be observed... I LITERALLY wore surgical garb, so no Hair, no NOTHING would inadvertently fall into the valve body... and I did the work on a sterile surgical drape.. Overkill?? Perhaps... but that's just me...

Of course, "usual" safety procedures must be observed. If you don't know what that means... then this job is NOT for you.. Do work at your OWN RISK!!

Cheers,
G

Re: Photo DIY- 722.6 Conductor Plate and Pressure Regulator Spring R/R

G-AMG,
Thanks a lot for your post.
I have couple of questions:

- You mentioned about plug on converter (pic 10 and 11). Which year is your W210? My S210 is 2000 and it doesn't have this plug there.
- Which IBM computer you are using for MBStar? T30? Will it fit for laptops without COM1 port?

Thanks!
