Removal and installation of ATF lines and radiator (VW Touareg 1)

Cleaning of ATF lines and radiator

If the ATF is contaminated or before installing a new transmission, blow out the radiator and ATF lines with compressed air (max 10 bar).

Thoroughly clean the ATF line/transmission, ATF line/thermostat, and ATF line/ATF cooler connection areas.

Unscrew bolt 1 and remove the ATF tubes from thermostat 2 (Fig. 3.61).



Unscrew the ATF pipes from/to the ATF radiator on the thermostat 2. While doing this, hold it on the thermostat.

Remove the ATF radiator and drain the oil.

Remove the ATF pipes from the transmission (fig. 3.36).

Connect the hose to the ATF transmission/thermostat tube and secure with a hose clamp. Place the other end of the hose in a suitable container.

Blow out the ATF tube with compressed air.

Connect the hose to the other ATF tube and repeat the process.

Lubricate the O-rings with ATF oil.

Install the ATF pipes and cooler.

Bleeding air from the ATF circuit

Check the ATF level and top up if necessary.

Carry out a test drive, during which the ATF temperature should reach at least 100°C, at which point air is removed from the ATF circuit.



After bleeding the ATF circuit, the ATF level in the gearbox decreases. Therefore, after the ATF has cooled down, check its level again.

Cool the ATF oil to below 30°C.

Check the ATF level again.
