Our '87 van has developed a whine in the AOD tranny. It occurs only in forward, not reverse. When I shift it into any forward position, with the brakes on, it starts. Not real loud, but enough to concern me. When I takeoff, it is there in 1st, quieter in 2nd, and not audible in 3rd or OD.
The fluid level is ok and is dark red/brown, which it has been for a long while.
Any ideas?
My wife usually drives this vehicle and doesn't know how long the noise has been there.I drove it today for the first time in several weeks and noticed it right away. Thanks.
