SUBJECT: MY - All, Models All with Transmission 722.6 or 722.9
Operating Fluid Specification Changes for Automatic Transmission
5-speed automatic transmission 722.6
Only use the transmission oils outlined in specification for operating fluids sheet 236.14.
See WIS document: BB.00.40-p-0236-14a.
MB part number - A001 989 68 03 10
7-speed automatic transmission 722.9 up to transmission production date June 21, 2010
Only use the transmission oils outlined in specification sheet 236.14
See WIS document: BB.00.40-p-0236-14a.
MB part number - A001 989 68 03 10
7-speed automatic transmission 722.9 after transmission production date June 21, 2010
Only use the transmission oils outlined in specification sheet 236.15
See WIS document: BB.00.40-p-0236-15.
MB part number - A001 989 78 03 09
Note:
The 2 different variants of 722.9 transmission oil are not compatible with one another and can not be mixed. The later oil can be identified by its
blue color as opposed to the former oil which is red in color.
Exception Note 1: Transmissions electrohydraulic controller units and torque converters made available through the parts department are checked at
the production plant with FE AT-134 only. This is why these parts may exhibit traces of FE ATF-134, In this case the transmission controller unit
and torque converter must not be cleaned. The transmission can be filled with the corresponding gear oil (as per this SI) immediately after it has been
installed.
Exception Note 2: Transmission 722.6, 722.9 up to transmission component serial number 2834526 may not be filled with FE~ATF 134.
Transmissions constructed after the June 21, 2010 transition can be visually identified by the following characteristics:
1. The oil pan has a noticeable change in the 4 dimples (pictured below).2010 Mercedes Benz Truck G 550 (463.236) V8-5.5L (273.963)
Page 50
2. The oil pan is 5mm deeper
3. The overflow pipe (inside the oil pan) is Green rather than black or white as on the earlier construction transmissions.
Xentry DAS version 05/2010 together with add-on 1476 displays a reference to the specified gear oil before reading out the transmission oil
temperature.
This information must be observed when filling the transmission.
