tranny has trouble shifting, shift up,down,up,down, at certian half pedal. shifts slow at full. to get into overdrive have to let off at leased to 1/4 pedal. Any easy fix, or find tranny shop.

Be interesting to see what you find. I have the same problem and about to head to the shop. I think the Edge Attitude toasted the tranny on my Truck
