A/T 4speed fails, car wont move until hot.
the big cable is the shift lever. im not talking that. if that is maladjusted. you may not get in to drive, or park or reverse... or Low.
the shifter controls the transmission MANUAL VALVE only. (and the od switch) the PRNDL valve and its switch, this cable allows you to shift to drive, and is calibrated too.
it's just a large shift cable that allows the driver to to shift gears.

then the skinny cable..... Mr, kickdown (aka , TV, throttle valve, or passing gear cable)
This kickdown, allows you to pass cars. you mash the gas to the floor and transmission down shifts. (to say pass a car on the road or go up hills faster) it also allows fast up shifts on flat ground.
it works both ways, too. if you are driving with heavy right foot, all shifts are DELAYED. (by design and need)
if your drive with a light right foot the trans upshifts fasters... sooner.....

this all 100% Hydraulics...inside..the box.. and cable, to your right foot.

so, if the cable seizes and is stuck out , guess what?, transmission is in passing gear full time. (aka real late shifting , if at all)
it can get stuck in any position, the fate of rust. (end the end they all rust)

the the cable disconnected top side
we can feel spring 17
if not , bingo.

my 2004 box still has this part. H25 engine attached.



to replace the cable the valve body needs to be dropped to see this cam 20.
used on vast toyota and volvos too. the A40 series of boxs. (Aisin/warner boxes of most kinds)
A prefix = Aisin made (company name)

The TCM also watches the TPS throttle angle, i do not know how the above and TPS inter act. are they additive? or averaged. or what? (secret TCM software inside)
but both do have an effect. (as is common, one may be a backup to the other. (either can fail)
