when driving in 4th or 5th, when i hit the "biting point" (the bit after the free play), so to say on the revs it lets out a high pitch squeal, happens in 5th @ about 2500rpm, as soon as i put my foot down abit more the squealing stops, until i bring my foot up and put the revs off, then it squeals again when passing this point. any ideas what it could be?, thanks, ryan
