    Need some help guys. Have a 1989 F-150. Truck is running fine. Problem, starting to downshift hard at times. Mechanic say their is a pressure valve that may be adjusted for shifting. I am no mechanic but if anyone has come across this problem any info would be helpful. Rarely shifts hard in drive (foward). Seems to shift hard when slowing down quickly. If not the valve. Any other things to check.
