ATF Level, Checking And Filling

Special tools and workshop equipment required

Used Oil Collection And Extraction UnitSMN372500
ATF Filler ToolVAG1924: an older ATF Filler ToolVAG1924 must be retrofitted. The width of the filling hook must be shortened to 20 mm. This is the only way possible to insert it into the ATF check hole. Deburr and clean the hook after cutting it.
Vehicle Diagnosis Tester, for example, Vehicle Diagnostic Tester

Procedure

WARNING:

Wear protective eyewear.

Test Conditions

The transmission must not be in the emergency running
The vehicle must be horizontal.
The selector level is in "P".
Exhaust hose/-hoses of an exhaust extraction system connected.
Engine running at idle.
The A/C and the heater are off.
Connect the Vehicle Diagnostic Tester, OBD and select vehicle system 02 - transmission electronics .
At the start of the testing, the ATF temperature must not be higher than 30 °C (86 °F); let the transmission cool down.

NOTE:

The Vehicle Diagnostic Tester reads the ATF temperature.

The ATF level will vary depending on the temperature of the ATF.

It is possible to overfill the ATF if the level is checked when the temperature is too low.

It is possible to underfill the ATF if the level is checked when the temperature is too high.

Overfilling or underfilling will influence the function of the transmission.

Only use the ATF available as a replacement part for the planetary gear in automatic transmission 09D. Other oils could cause malfunctions or damage the transmission. Follow the ATF specifications provided in the Parts Catalog for the appropriate engines.

CAUTION:

Do not start the engine or tow the vehicle if there is no ATF in the transmission.
Too little or too much ATF will impair the transmission.
Perform this check twice if the ATF circuit to the cooler was opened during a repair. Important: The ATF must be at least 80 °C (176 °F) after the first check. Perform a road test with tester. Check the ATF level after it has cooled down as described.

ATF, Checking Level and Correcting

Tightening specification. Refer to OIL PAN, OIL STRAINER AND VALVE BODY .

NOTE:

The ATF level is checked at the ATF check hole.

The ATF level is correct if a small amount of fluid drips out of the check hole (this is normal because the fluid expands as it heats up) between 35 ° and 45 °C (95 ° and 113 °F) (for hot countries 50 °C (122 °F)).

-- Drive the vehicle onto a 4-column hoist or over a service pit so that it is absolutely level.

NOTE:

To check ATF level, it is necessary to modify an older ATF Filler ToolVAG1924. The width of the filling hook must be shortened to 20 mm. This is the only way possible to insert it into the ATF check hole.

Deburr and clean the hook after cutting it.

-- Fill the reservoir on the ATF Filler ToolVAG1924 with ATF for the automatic transmission 09D; for the correct ATF specification. .

-- Start the engine and let it idle.

-- With engine idling depress the brake pedal and shift the selector lever through all the selector lever positions leaving the selector lever at least 10 seconds in each position.

-- Place the Used Oil Collection And Extraction UnitSMN372500 under the transmission.

Test Temperature 35 ° to 45 °C (95 ° to 113 °F)

-- When the ATF reaches 35 °C (95 °F), remove the ATF check plug -arrow- and drain off any excess ATF if necessary.

NOTE:

The ATF inspection plug must be installed again before the ATF reaches a temperature of 45 °C (113 °F) (50 °C (122 °F) with hot climates).

If ATF leaks from ATF check hole before temperature has reached 40 °C, ATF level -arrow- is OK.

If no ATF drips out of the ATF check hole before 40 °C (104 °F) is reached, then the ATF level -arrow- is not OK. Fill is necessary. Refer to ATF LEVEL, CHECKING AND FILLING .

If ATF is OK:
