bgood Posted June 15, 2009 Share Posted June 15, 2009 I have a Fusion 1400 TDCI Diesal 2007, mileage 21k. While accelerating from stationary, each time I change gear particularly from 1st to 2nd & 3rd gear, there is a clonking from the transmission. Doesn't occur when decelerating. Suspected backlash maybe in driveshaft. Garage is unable to diagnose but acknowledge the problem (its not engine mounting problems). Any suggestions? Thank you.

bgood Posted June 16, 2009 Author Share Posted June 16, 2009 Thanks for your reply. Gearbox mounts have been checked by ford main dealer and are ok. I believe there could be movement in the spline in the driveshaft. When I dont use the clutch and accelerate there is no noise. My other thought is theres somethimg wrong with the clutch. But ford say everything is ok. Quote Link to comment Share on other sites More sharing options...

I also have this problem on my 1.4tdci 57, had car nearly a year but this clonk doesn't seem to get any worse. Guess it might be inherent in the build. I drove a Fiesta petrol model recently with less mileage than mine, the gearbox change was a lot sloppier than mine, so maybe this is just tightness and may get better. As I say, it has not got any worse in the 12 months I have had my car. Quote Link to comment Share on other sites More sharing options...
