just been playing with an st220 mondeo.....and when we set off,from 3rd to 4th my car didnt half crunch. the car did not go into gear when it crunched it just hit a "so called wall"after i gathered thought ans relaxed it went in easy. now the gear box does not whine etc so i dont think its that,is it me rushing things,not dipping the clutch properly? HELP!
