Hi I wonder if anyone could help me, Ive got a 2008 2.8 diesel grand voyager and when its in neutral the get doesn't move, when you try and push it and when its in reverse there seems to be a lot of resistance, the same when its in drive, it will move but with a lot of putting your foot on the accelerator. I'm completely useless and anything mechanical and really need to know , what the problem is, roughly how much it would cost to get fixed and where can i get it fixed. Phil, from Sheringham
