gearbox oil March 17, 2022, 05:03:26 PM I thought I would change the oil in my gearbox as it is not a scheduled item. Bought the correct oil drained the contents of the gearbox about 1/4 liter of oil drained out. Luckily the car has not been driven far and the gearbox appears fine. 2 liters refilled and all ok. Just a warning for owners to remember to check the level occasionally. Could save a lot of grief.
