I run a 1988 944 Lux in black with 118,000mls on the clock, it has developed an irritating whinning noise from the rear at anything over 20mph but below this it is fine, am I right in thinking this is the gearbox as I have read a lot about this problem and that it can be solved by using a new type of oil, think its called Swepco, has anybody tried this, is it any good? I would appreciate your views, cheers.
