Since buying my diesel Connie a few years ago I've covered 35,000 miles with a slight issue that's a bit of an annoyance . It was getting on my wick yesterday on a drive back from Dumfries so gave me time to ponder.
When driving in top gear and beginning to increase load to climb a slight incline, as my speed increases to between 50 to 55 mph I get a judder from the drive line as if I have a worn ball joint but having checked these and the car has passed all it's MOT's with this fault, I'm wondering if I have a torque converter lock up fault. If I press the accelerator whilst this judder is taking place and get the car to drop to 4th gear , the judder stops and as the speed increases above this speed and the gearbox changes back to top gear and no further judder below or above this speed and otherwise the gearbox is smooth and a joy to use. It just feels as if you are on a rough road surface when this occurs !
