Alright guys I have searched this forum for 3 days now and I cant find a straight answer for what is going on with my truck. 2001 F350 156000 miles. A few days ago the transmission started shifting hard from 1-2 only after I get to about 25mph or around 3000 rpms. When I let out of the pedal, it will shift and 2-3 and 3-od shifts are fine. This happened one time before about 4 months ago, and then all of a sudden now. I know I may need a rebuild but any help will be appreciated.
