Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
4.0 Checking Transmission Fluid Level
Due to the substantial expansion of transmission fluid when heated it is only possible to measure the oil level correctly at specified oil temperatures (after driving a distance of about 12 mi./20 km). All transmissions should be checked between a

All 5 and 6 speed transmissions require the fluid to be checked when fluid temperature is between 30-50° Celsius using DIS Plus or GT1. Do not check fluid level after temperature has exceeded 50° Celsius.
A4S 270R, A4S 310R and A5S 360R
See appropriate AUTOMATIC TRANSMISSION article for fluid level check procedure. These transmissions generally do not have a dipstick and fluid level check (if necessary) must be performed through the oil fill hole.
