Hello people, I need to do a 100000kms service on a 2000 5 speed manual Caroller. I've worked out all the parts that I need to change, and I am going to change the gearbox oil too. Only i've never done this and would like to know what the best approach. I was thinking of dropping the oil in the box (where is the plug?) then cutting a peice of garden hose to put in the fill hole (where the fill hole?) leading to a funnel and getting the oil in like that, coz I don’t have one of those pump thingos on those 20L drums, will this work? Whats a good grade oil to use in the box too? I was thinking Castrol VMX80 or a 75w85 grade! you help is much appreciated
