Hi,
I swapped a 4.9l into a 1997 F350 4x4 that originally had a 5.8l. I have everything working but tranny seems sluggish in drive. Reverse and using 2nd gear takes tight off. Is there a kick down or other cable I might be missing? The tranny was never removed from the truck and worked good before the swap.I did not remove original engine I only installed the 4.9l and got it running.
