a4ld problem

[puty72]

well first of all my truck is an 89 with 2.9 engine and a4ld auto tranny. Anyways my transmission shifts smooth threw every gear but doesnt shift into overdrive until 75mph. Im pretty sure my speedometer isnt off that bad so i was wondering what the problem could be. Also going up a hill at say 55mph it with drag that gear on.
