Transmission fluid or gear oil lubricates, cools and supports smooth operation. The correct service interval and procedure depend on the transmission type, vehicle specification and actual condition.
What to keep in mind
- Watch for delayed engagement, slipping or harsh shifts.
- Check for leaks and changes in fluid colour or smell.
- Use only the specified fluid type.
- Diagnose shift problems before assuming fluid alone will fix them.
A condition check helps determine whether a drain-and-fill, machine-assisted service or further diagnosis is appropriate.
