GT 6th gear only judder and rev problem
A couple of months ago I noticed that there was a judder in 6th gear between 2000-2500 rpm in my GT 1.9 JTDm. It was not very annoying so I didn't care about it.
However, today I felt a lack of power in 6th gear and tried to find the reason. Then I noticed that when the car is in 6th gear and I give full throttle around 2000-2500 rpm the revs go up to 2800-3000 but the car barely accelerates. Then the revs and speed match around 2800rpm.
First I thought that the clutch was gone and it was time to replace but then I saw that this does not happen in other gears. Only in 6th, and only between 2000-2500 rpm. The car currently has 105.000 km on the clock (around 65k miles) and as far as I know the previous owner changed the clutch at 70.000 km (45k miles).
Do you think it is the clutch or is it possible that there might be another reason?
