My truck's just about to pass 200,000 miles the oil hasn't been changed for 40,000 miles and it's allways been hard to get into gear ever since i've had it
admitedly mine needs a new clutch adjuster and cable but i'll get round to it, the last box (had a second hand one 30,000 ago) was exactly the same.
They last well these ols diesels but are noisy and shake a lot if the idle is too low or the mounts are worn, did the first mechanic actually take the rocker cover off? if not he has no way of knowing what it needs!
get a 3rd opinion if possable, very few mechanics are good enough to diagnose a noise without further investigation
