IIRC from another recent thread the 4r70w was introduced in this generation truck, sometime in the '92-96 F150s and then carried over to the '97+. It's an electronically controlled variant of the AOD.

Does any body have any opinions on this tranny, good or bad, known problems? I ask because sometimes it acts like it dosent want to drop into first or passing unless you floor it all the way.like if you are slowing to a stop for a light then the light turns before you stop all the way, i try to get back on it and it just dosent seem to respond.???

The 4R70W isn't a POS but it's not as strong as an E4OD. If it's not kicking down then it's probably something simple. When was the last time the filter was changed? I don't know much about this particular tranny but I think not kicking down would have more to do with what controls the tranny rather than a shot transmission itself.

Yes.. just like the E4OD this gearbox is completely computer controlled so the first step in diagnosing a problem should always be to pull the codes.
