won't kick down ??
i have a 93 f150 5L AOD.... she just won't kick down and in my year i was told it should still be mechanical. any ideas .....
and i am hoping to bring the truck up on a hoist to check my kick down adjustment and hopefully she's just not been adjusted properly.
thnx cheers

There is no "kick down" adjustment on an AOD. The cable running from the throttle to the transmission controls the pressure. Improperly adjusted it will burn up the transmission very quickly.

i guess i mis-understood my repair guide or something lol
so with no adjustment then what might be the problem??
i have to force it into low gears if i want the same effect...

There an adjustment for pressure but it is critical to be very close to factory setting. A small adjustment can be made but tends to effect upshift not downshifting. Still a good idea check it.

I'm familiar with the 4R100 in my Lightning but new to the AOD. Are there shift improving aftermarket valve bodies available like for the 4R100 or only shift kits? And would either of these help with slow or lagging kick downs?

The AOD shift kit vastly improves shift firmness but it won't fix a pre existing problem. Are you sure your truck has the all mechanical AOD? What is the trans code on the drivers door pillar?
P.S. If you're used to droving one of the electronically controlled transmissions where even a slight blip of the throttle produces a downshift then you have some getting used to with the AOD, downshifting from OD takes a large throttle input and what may seem like an eternity.. it really doesn't want to do it and I think they were deliberately configured this way. The upside of this is it can be driven more like a manual truck and you will find you can actually load the engine and produce acceleration or climb a grade without a downshift.. assuming the truck has enough engine torque output and favorable axle gearing of course. This allows trucks with this trans to return some truely remarkable hwy fuel milage.

What year is your truck? Must be 1994 or newer?
Either way, Trans Code U = 4R70W
It's electronic controlled just like an E4OD, but the design is based off the AOD.
