my 5hp24 auto experience a probelm like this:
normally when you leave the foot from gas, the auto gear box should stay in high gear to let the car run freely. but my auto box will stay in that ever gear it is, so the car will slow down fast. the car has done about 100,000miles. no fluide or filter ever changed. other than this 'probelm' . the car drives OK. waht could be the cause? should I get the fluide and filter replaced? does this show the sign of series problems ....?
