Only acquired the vehicle 2 weeks ago so I don't know any history. When I got it I had no problems, then the last couple of days the gearbox has been getting tight. Today I've been unable to select 5th or reverse. First to fourth is alright but I can't get the gear stick through the gate for the others. This is my first P38, my last RR was the classic, I'm wondering if this a common P38 problem or am I in the sticky and smelly?
