Hi, I have a '01 Ford F-250 diesel 96000 miles. It is an automatic transmission. At approximately 75000 miles, the front seal leaked and was replaced. When I got my truck back, it shifted really hard, it would almost redline before it would shift into gear. Also, the overdrive light would flash on and off. I took it back to the same shop and he said I needed to replace the whole transmission. I wanted a second opinion and took it elsewhere. Turns out, the first mechanic forgot to plug in a wire that tells my transmission how fast the truck was going so it didn't know to shift. Transmission shifts great now. The overdrive light doesn't flash until I get up to 75 or 80 mph. Also, since this whole fiasco, my truck gets way worse gas mileage! Any suggestions? I have replaced the fuel filter also. Thank you for your time.
