i have got a ford mondeo 2.5 v6 auto.when drivern at more than average revs inbetween changing gears it makes a sort of vibration noise. i have changed the gearbox oil.this did not make a diffrence.could the corse of this be the filter.i do not know where the filter is?
you have to strip the gear box down. i looked like you and was told if you clean it the gears will come back. ive just got a gear box off ebay £250 and im fitting myself. would have cost £1.100. to rich for me good luck
