weird mis shifting 07 ranger 3.0 automatic
I just got a used 07 3.0 auto with 21k on it. Sometimes when I give it more than a little gas but not flooring it, it does this weird misshift thing, especially if im going up hill. Its like it shifts down then up or vise versa real quick like thump thump in 1 sec before its decides which gear to use. Any of you guys ever had this?
I took it to ford and they kept it a few days and did a buntch of stuff to it and updated the "firmware" of the tranny computer apparently. Now it shifts more naturally but that weird misshift thing is still there if I drive even slightly aggressively with it.
Any feedback is appreciated.
