Graham Lange, proprietor of Horton Cars in Buckinghamshire has put EDT’s automatic transmission machine through its paces, declaring himself “astonished” by the results. The independent Volvo specialist said the machine helps ease the removal of oil from automatic gearboxes, usually a tricky process. Lange explains: “Using the EDT machine you can remove all of the oil from the gearbox, cleaning out every last little bit in there. That’s simply not possible by draining the oil and replacing it: even if you flush it two or three times you won’t get the same result that you do with the EDT machine.”
