Audi Workshop Service and Repair Manuals

Notes:

• ◆ Always replace valve body if it has collected dirt or if it is defective.
• ◆ General repair instructions .
• ◆ Rules for cleanliness when working on the automatic gearbox => Page 37-147.

Removing

• ‒ Remove oil pan => Page 38-19.
• ‒ Remove ATF screen => Page 38-21.

• ‒ → Disconnect the retainer clips for wiring harness connector -arrow-.

For gearbox with hydraulic control E17 only

• ‒ → Unplug connector at gearbox speed sender -G38 -arrow-.

• ‒ → Unscrew securing bolts -arrows- on valve body and take out valve body together with wiring harness.

Notes:

• ◆ Only slacken the securing bolts -arrows- indicated in the illustration.
• ◆ If other bolts are slackened, this may affect the operation of the valve body or the valve body will come apart.
• ◆ The bolt -arrow A- is shorter and thinner than the other bolts. Note allocation

For gearbox with hydraulic control E18/2 only

• ‒ → Unplug connector at gearbox speed sender -G38 -A-.
• ‒ Unplug connector to Hall sender for gearbox input speed -G182 -B-.

• ‒ → Unscrew securing bolts -arrows- on valve body and take out valve body together with wiring harness.

Notes:

• ◆ Only slacken the securing bolts -arrows- indicated in the illustration.
• ◆ If other bolts are slackened, this may affect the operation of the valve body or the valve body will come apart.
• ◆ Bolt -arrow A- is not fitted on gearboxes with hydraulic control E18/2 and can therefore be ignored here.

All models:

• ‒ Remove valve body from gearbox, at the same time guide out connector for wiring harness.

Note for gearbox with hydraulic control E17 only

Do not stand the removed valve body on the gearbox input speed sender on the rear side of the valve body. This may cause damage.

Installing

• ‒ Coat O-rings of wiring harness connector thinly with ATF.
• ‒ Fit wiring harness connector into gearbox housing.
• ‒ Installation position: Flat part of rear shoulder faces oil pan, the lugs at shoulder are horizontal

For gearbox with hydraulic control E18/2 only

• ‒ → Route wiring with connector -C- according to illustration, so that wiring does not get stuck when installing valve body.

All models:

• ‒ → Position the valve body without applying force while inserting the bolt in the engaging plate -1- into the slot of the selector slide -2-.

• ‒ → First tighten valve body bolts -arrows- finger tight.

Notes:

On gearboxes with hydraulic control E17 bolt -arrow A- is shorter/thinner than the other bolts. Note allocation

Bolt -arrow A- is not fitted on gearboxes with hydraulic control E18/2 and can therefore be ignored here.

• ‒ Then tighten the valve body bolts (starting from the inside and working outwards) to their final tightening torque.

For gearbox with hydraulic control E18/2 only

• ‒ → Pull wiring with connector -B- of Hall sender for gearbox input speed -G182 upwards between valve body and wiring harness.
• ‒ Connect connector -B- to connector -A- at wiring harness.
• ‒ Connect connector -C- to gearbox speed sender -G38.

For gearbox with hydraulic control E17 only

• ‒ → Connect connector -arrow- onto gearbox speed sender -G38.

All models:

• ‒ → Push retainer clip onto wiring harness connector -arrow-.
• ‒ Install ATF screen => Page 38-21.
• ‒ Installing oil pan => Page 38-20
• ‒ Top up ATF => Page 37-139.
