I am new here, so any help would really be appreciated. I recently had a new clutch kit installed in my 850 non-turbo. Flywheel is new also, and although the car shifts into gear just fine, when engaging the clutch while at speed in between gears, there is a clunk or a slap of some sort that i can feel directly from the pedals as if there was a motor and/or trans mount gone bad, i checked these out, they are just fine, i also went and re-tourqued all bolts and supports that were take out or lossened while job was done (cradle, control arms etc.) it is still there and the shop refuses to accept any responsibility. My car was tight and sound before they did the job...any suggestions please?
