Do not drain oil. A “removed” mechatronic unit is sent back

with its oil in.

Installing
• All selector forks must be “in neutral” prior to installation of

mechatronic unit

Note

Make sure that all selector forks are located in -N-, “in the middle”, and therefore that the gearbox is in neutral.

– Therefore, check each of 4 selector forks by hand.

disengage all gears and return selector forks to middle position

“neutral”.

Note

“Neutral, neutral, neutral”, or gearbox will not function!

You can turn the front gear slightly for assistance. This makes it

“easier” to shift the forks.
– Please clean sealing surface where mechatronic unit will

make contact later on.

Oil residues on sealing surface will later result in a misdiagnosis

of “leaking”.
– Screw in guide pin -T10406- hand-tight.

Make sure that all 4 gear actuators project 25 millimetres -a-.
