How much Trans Tune for my 1992 Ford F150? [SOLVED]

I have a ’92 F-150 with an E4OD, which is a physically large transmission. It shifts hard when shifting from park to reverse, or drive to reverse. How much Trans Tune should I put in it?

Hi Troy. One 16 ounce can of Trans Tune is plenty per ATF interval. Just pour it down the ATF dipstick tube and drive. If the shifting problems are caused by sticky fluid varnish you should be able to notice an improvement within 50 to 100 drive miles.
