Checking the oil quality and the oil level in the transmission

Note! Transmission fluid quality and level are extremely important for the function of the transmission. Therefore it is imperative that these are correct. In addition the oil level is dependent on oil temperature.




- Ignition on.
- Read off the oil temperature.
Check the transmission oil level. If the oil level is low, check the transmission for leakage, then top up with oil.
Check the quality of the oil.

Checking the neutral check




- Start the engine.
Move the gear selector to position D. Drive a short distance, stop and brake the wheels. Allow the engine to run at idle speed and hold the brake pedal depressed. Wait until the neutral check has been activated (it can take up to 30 seconds).
Quickly depress the accelerator and at the same time check if the transmission slips abnormally at "take off".
If the transmission slips abnormally, the transmission's control system must be replaced.

Verification




Verification

Hint: After carrying out the repair, check that the fault has been remedied.








- Ignition off.
- Reinstall the connectors, components etc.
- The gear shift position sensor for the transmission must be calibrated if the control module has been disconnected.

Hint: Select Diagnostics/car communication.

- Start the engine.
Test drive the vehicle following: Test drive schedule, description, B6304T4, TF-80SC AWD, B6324S5, TF-80SC AWD, B6324S5, TF-80SC, B6324S4, TF-80SC, B6324S4, TF-80SC AWD Test Drive Schedule, Description
Check that the transmission does not display any obvious function faults.

Note! When test driving, the oil temperature must be above 20 °C.

Fault-tracing information
The fault should have been detected and remedied. As this is not the case fault-tracing has failed.
Exit fault-tracing for this diagnostic trouble code (DTC) or make another attempt.

Do you want to exit fault-tracing?

Yes - Exit fault-tracing

No - Attempt New Test

Resetting the "Transmission fluid change" counter

Checking the function

Hint: The transmission control module (TCM) has a counter for fluid quality that counts the number of times the transmission is subjected to too hard a load or too high an ambient temperature. If the counter is not reset during draining/replacement, there is a risk that a diagnostic trouble code will be set under the wrong conditions. Thus, it is important that the counter for transmission fluid change be reset.

Note! This only applies when the transmission oil is changed and when the oil is changed during repairs to the transmission's temperature sensor.




- Ignition on.
Click on the VCT2000 symbol to reset the counter.
