I have a 1998 F-150 XLT 2WD with 4.6L engine with 180.000 miles on it.
And i guess I have the 4R70W
When overtaking the transmission kicks down, but will not engage the next gear at high rev. unless i step of the gas a little bit (then the turbine gives you a REAL kick)
Reading in this forum i have found out that this problem probably could be solved installing a B&M shift improver kit, specially since the tranny has a couple of miles on it.
Correct me if i'm wrong.

mine used to hold the lower gear if i had it on the floor for a long time, once i let off it would upshift. the shift improver kit did "fix" it..... i think. it still holds the low gear until i start to let off the gas pedal but not like it used to where i had to let go of the gas completely.
i'm not really sure if it's actually a problem to being with. i think it's a built-in gaurd for o/d because aparently it's a pretty weak band in the transmission. high power shifting puts alot of stress on it so the computer says no shifting until the rpm's come down a little along with closing the throttle a little.
all i can say is the shift kit was definitely worth it either way.
