The minivan is equipped with a button on the gear shift. This button enables you to shift out of overdrive when you do not want the vehicle to be in overdrive mode. About this time the fuse in the fuse box would blow. Replaced the fuse a number of times but the problem is still there. The fuse may last for 5 to 10 miles and then it would blow. Tried a larger amp fuse but it would also blow. Transmission will leave the overdrive only if you accelerate going up a hill.
