Advice needed, I think the auto box on my 98 3.3 voyager has completely gone now, was making allot of whinning noises, changed the oil,which was burnt and brown, seemed to work, now whinning noise back again and it will only go in limp mode, so now i assume gb needs replacing, so are you able to remove gb without taking the whole engine out, and been looking on ebay etc for second hand low mileage units but they seem to have codes on like COO or EGA how do i find out what mine is? HELP PLEASE
