1992 ford conversion van shifting hard
I had a 1992 Ford conversion van with a 351 eng and 4 speed transmission that I had rebuilt at 160,000 miles before giving it to my son. It now has 189,000 on it and is shifting hard when driving norm...

Transmission is original rebuilt at 160,000 miles. Towed a 1500 lb boat. The part that is confusing is that it shifts so much better manually than when left in D. Does vacuum control shifting in a 1992 or controlled by computer?
