of repairs or for service fills.
2.6 Transmission oils, sheet 235.11
The fully synthetic gear oils are approved for all MB commercial vehicle manual transmissions installed
in MB vehicles with steel/molybdenum synchronization with and without oil coolers, in MB transfer
cases with and without oil coolers as well as in ZF manual transmissions with steel/molybdenum
synchronization.
Due to the favorable viscosity/temperature characteristics, a good cold-shifting response and, due to the
composition of the transmission oil, a good thermal/oxidative stability of the oil at high transmission oil
temperatures as well as a fuel savings potential depending on the operating conditions can be expected.
2.7 Engine oils, sheet 235.12
The engine oils must be used with a common oil system for transmissions used in tropical countries, and
for manual transmissions with a torque converter and clutch unit. These engine oils display the very high
seizure resistance required for use in transmissions. The oils need not comply with the engine oil pour
point specifications in these Specifications for Operating Fluids.
2.8 Engine oils, sheet 235.27
Commercial vehicle retarder oils: the products listed in the tables apply to commercial vehicle
transmissions: see MB Specifications for Operating Fluids 231.2. The engine oils are suitable for retarder
use. The oils need not comply with the engine Specifications for Operating Fluids 231.2. The engine oils
are suitable for retarder use. The oils need not comply with the engine oil pour point specifications in
these Specifications for Operating Fluids.
3. Automatic transmission fluids (ATF), sheet 236.1/.2/.3/.5/.6/.7/.8/.81/.9/.10/.11/.12/.13/.20
ATFs are comparatively low-viscosity gear oils which, due to their universal use potential as a gear oil or
a hydraulic fluid, can cover a wide spectrum of applications. The ATFs in the individual their universal
use potential as a gear oil or a hydraulic fluid, can cover a wide spectrum of applications. The ATFs in the
individual sheets differ essentially due to their inherent friction coefficients in tribological contact. This
property predestines these oils as function fluids for automatic transmissions whose ease of shifting,
among other things, is considerably affected by the friction coefficient of the ATF. Therefore, to achieve
optimum performance of the vehicles, only the ATF quality (sheet no.) assigned to the major assembly is
to be used. The individual ATF qualities will be described in greater detail below.
3.1 Automatic transmission fluids (ATF), sheet 236.1
The approved ATF correspond to the currently no longer valid GM specification Dexron II-D or the
currently valid GM specification Dexron III.
The field of application of these ATF includes MB automatic transmissions without controlled torque
converter lockup clutch in passenger cars, ZF Ecomat transmissions, Allison automatic transmissions,
Voith-Diwa transmissions and MB automatic transmissions in commercial vehicles and busses except

Fig. 644: Automatic Transmission Fluid Sheet
3.5 Automatic transmission fluid (ATF), Sheet 236.6 and 236.7 , for MB automatic transmissions
without regulated torque converter lockup clutch in passenger cars and commercial vehicles and buses
(W4B035 only as of major assembly end no. 005733), ZF Ecomat transmissions, Voith-Diwa
transmissions, commercial vehicle and cross-country vehicle power steering systems. If the approved
ATF according to sheet 236.2 are not available, ATF according to sheet 236.6 can be used in
synchronized passenger vehicle manual transmissions, except GL 76/30-5 and GL 275E (the two sports
transmissions always require ATF according to sheet 236.6) as a makeshift measure.
The approved ATF according to Sheet 236.6 and 236.7 correspond to the currently no longer valid GM
specification Dexron II-D. The kinematic fresh oil viscosity at 100°C must be at least 7.0 mm
2 /s, after
shearing (as per CEC- TLPG 7) at least 6.0 mm
2 /s.
3.6 Automatic transmission fluid (ATF), Sheet 236.8 , for ZF Ecomat transmissions, Voith-Diwa
transmissions, MB automatic transmissions in commercial vehicles and buses except W4B035 and MB
automatic transmissions without regulated torque converter lockup clutch in passenger cars (only in arctic
climates).
The approved ATF correspond to the no longer valid GM specification Dexron II-E, Allison C4, Voith
lubricant lists G 607 and G 1363 as well as ZF lubricant specifications TE-ML 14.
Automatic transmission fluid (ATF), sheet 236.81 , for MB automatic transmissions without controlled
torque converter lockup clutch in passenger cars, MB automatic transmissions in commercial vehicles and
buses except W4B 035 as well as ZF Ecomat transmission, Voith-Diwa transmission.
The approved ATF corresponds to the ZF lubricant specifications TE-ML 09, TE-ML 14 and the Voith
lubricant lists G 607 and G 1363.
Automatic transmission fluid (ATF), Sheet 236.9 , for MB automatic transmissions without regulated
torque converter lockup clutch in passenger cars, ZF Ecomat transmissions, Voith-Diwa transmissions,
Allison transmissions.

The ATF correspond to the valid GM specification Dexron III, Voith lubricant lists G 607 and ZF
lubricant specification TE-ML 14.
3.9 Automatic transmission fluid (ATF), Sheet 236.10, for MB automatic transmissions with and without
regulated torque converter lockup clutch (GKUB) in passenger vehicles. This ATF is provided ex works
as lifetime oil in all MB automatic transmissions with regulated torque converter lockup clutch - model
series 722.6 - in passenger cars. For repair work, only the ATF quality specified in sheet 236.10 may be
used for refilling in this new generation of automatic transmissions, and this can be obtained in a 1 liter
container under the part no. 001 989 2103.
All MB automatic transmissions without regulated torque converter lockup clutch in passenger vehicles
can either be filled with the ATF according to Sheet 236.10 or the ATF according to the Sheets
236.1/.6/.7/.81/.9.
3.10 Automatic transmission fluids (ATF), sheet 236.11 , for ZF automatic transmission "IF 4 HP 20"
and the automatic transmission oil circuit of the VW automatic transmission "AG4"
The approved ATF are usually only used in the event of repair or for refilling.
3.11 Automatic transmission fluids (ATF), sheet 236.12 , for 7-gear automatic transmission oils (ATF), is
also downwards-compatible for all 5-gear automatic transmissions.
3.12 Sheet 236.13 , repair solution for MB automatic transmissions without regulated torque converter
lockup clutch in passenger cars with the complaint of "double harsh engagement after engaging drive
mode D", the MB automatic transmission fluid - part no:.
A 001 989 2303 11 - and/or the ATF "ATF MB 274" from Exxon Mobil Corporation, Fairfax, Virginia,
USA, must be used. The ATF "Shell ATF MB" and/or the MB automatic transmission fluid with the part
no.: A 001 989 0703" previously approved for the above-mentioned application must no longer be used,
but can be used up as an ATF for oil changes necessary as a result of maintenance.
