Hi newbie here, glad to be onboard. I had the clutch replaced on my mk 4 mondeo powershift auto estate last year. Yesterday I had the oil and filter done in the gearbox. The filter was heavily contaminated with swarf. Is it possible that when the clutch broke, it contaminated the oil filter in the gearbox, or might there be internal gearbox damage. Car drives fine, bit jerky at low speed. The oil seal on the crankshaft rear was replaced as it was leaking. Any suggestions/thoughts gratefully received
