2.2
Calculation of gear ratios
Example:
7th gear
Final drive
Drive gear
ZG1 = 49
ZA1 = 17
Driven gear
ZG2 = 32
ZA2 = 71
i = Z2 : Z1 (Z1 = number of teeth on drive gear, Z2 = number of
teeth on driven gear)
iG = Gear ratio = ZG2: ZG1= 32 : 49 = 0.653
iA = Final drive ratio = ZA2 : ZA1 = 71 : 17 = 4.176
Overall ratio = total ratio = iG x iA = 0.653 x 4.176 = 2.730

Caution
Risk of damage to gearbox.
♦ Only the gearbox oil for the 7-speed dual clutch gearbox
0CG, which is available through the replacement parts
system, must be used ⇒ Electronic parts catalogue “ET‐
KA” .
♦ Other oils will lead to malfunctions or failure of the gear‐
box.
♦ It is not possible to check the fill level of the hydraulic fluid
section of the mechatronic unit for dual clutch gearbox -
J743- . Before repairs, the breather of the mechatronic unit
for dual clutch gearbox -J743- must be sealed so that no
oil can escape.
♦ If any oil escapes from the hydraulic fluid section of the
mechatronic unit for dual clutch gearbox -J743- , the oil
must not be filled back into the mechatronic unit!
♦ If the hydraulic line between the valve block of the me‐
chatronic unit for dual clutch gearbox -J743- and the con‐
nection for the disengagement clutch of the electric drive
motor -V141- is being removed, seal all connections with
suitable sealing plugs. After reinstallation of the hydraulic
line, hydraulic fluid must be replenished through the
breather connection of the mechatronic unit , if necessary.
For allocation of the sealing plugs, hydraulic fluid and fill‐
ing equipment refer to ⇒ Electronic parts catalogue .
♦ If oil escapes from the gearbox oil section, it can only be
rectified by changing the gearbox oil. It is not possible to
check the fill level.
♦ If the level of oil/fluid is too high or too low in either of the
parts, the function of the gearbox will be impaired.
