Morning guys,
I'm sorry to bump this but I'm in a real dilemma, I've got the Macmillan 4x4 in a few weeks and I just want to make sure my gearbox isn't getting shagged!! I've got to take the 90 to the guys that did my clutch and disco transfer box/def transfer box swap to have the transfer box oil replaced (agreed that we would run some miles through it to clear any **** before its changed)....anyways, I don't know enough about gearboxes so if someone can shed some light on this I'd really appreciate it! Basically oil that came out of gearbox was black which I've read isn't good, but the gearbox shifted lovely and didn't make noise...now that they have changed the oil it whines (as if you were reversing) in 4th and 5th under power and on decelation (doesn't make noise while coasting) and I've checked this in low and high box and its the same so it is defo the gearbox...what shall I say to them?
