Fluid - A/T: Testing and Inspection

Oil Level, Checking

Warning! Oil grade: Only automatic transmission fluid (ATF). Dexron III (the fluid must have a G license). This is usually given as "Dexron III (G-xxxxx)" where xxxxx is a 5 digit serial number. "Dexron III-G" (without a number) may also occur. The Volvo P/N for this oil is 1161521-8 (1 liter container).

Warning! Avoid skin contact with the transmission fluid.

Conditions





The difference between the MAX and MIN volumes is 0.5 liters. Check the oil temperature in the transmission.
At room temperature (+20°C) the oil level is close to the MIN mark on the "cold area".
At room temperature (+20°C) and low oil level the oil barely reaches the dipstick.
The "cold range" (+40°C) is reached after approximately 15 minutes idling in the workshop, while the "hot range" (+80°C) is reached after approximately 30 minutes highway driving at an air temperature above +15°C.

Note! Carry out the check at an oil temperature of +80°C. Go to car communication function group 4. Select the digital display parameter. Select the parameter for the transmission oil temperature.

Preparing to Check the Oil Level
- Park the car on a level surface.
- Apply the parking brake.
- Apply the foot brake.
- Let the engine idle.
- Move the gear selector lever to position P.

Move the gear selector through all positions. Wait in each position for approximately 3 seconds
Move gear selector to position P and wait approximately 2 minutes before checking the oil level.
The dipstick must be pushed down as far as possible into the dipstick tube.

Caution! Wipe the dipstick with a nylon cloth or similar. Do not use a cloth which may leave fluff or threads.

Low level (topping up)
Top up with oil through the dipstick pipe
Take account of the temperature when topping up with oil.

High level (overfilling)

Warning! The oil may be very hot if the car has just been driven. Avoid skin contact with the transmission fluid.
The transmission must not be operated if the oil level is too high. This can cause increased operating temperatures and oil leakage.

Drain off oil





- Undo the drain plug.
- Allow some of the oil to drain out and reinstall the plug.
- Tighten to 40 Nm
- Check the level taking account of the temperature.
- Move the gear selector through positions. Wait in each position for approximately 3 seconds.
The oil can also be sucked out through the dipstick pipe using an oil suction syringe with a narrow gauge hose.

Note! Strict cleanliness is important.
