Hi, I work for land rover and if we have a problem with a noisy gearbox or it is difficult to select gears then the gearbox gets drained and refilled with ATF (dexron3) Can anyone tell me if it i´s advisable to do the same with the Volvo v40 (renault gearbox) not that I bugger up some seals or something like that. Thanks for your replys in advance. GGG
