Hi Guys. I have that feeling that my transmission might be low on oil. Gear shifts are okay but not as smooth as it should be. I have a 2.2 diesel X Type 6 speed manual. I came across a few videos on youtube for the v6 x type and that gearbox takes 1.75 litres of oil. I would like to know how much oil does the 2.2 diesel 6 speed take and what kind of oil should I use. Thanks in advance for the reponse.
