[V8] A few issues with my '93 4.2

[Greg Furstenwerth]

 From when I was asking about the Kickdown due to it acting weird on 
mine. I have over 7000 archived V8 list mails :)

Mine runs exactly the same as Greg's, for what it's
worth.  It will not downshift in "E" on the highway. 
In "S", it will instantly downshift and take off. 
However, with the added juice of the 4.2, I've never
found the 55-75mph run in "E" to be that lacking.

Hey Lawerence,

The kick down switch is built into the throttle cable and has a known
failure issue.  I replaced mind a few years back for around $100 (?). 
The switch is built into the throttle cable (it is the box that sits
flush with the engine side of the firewall) and operates when you
create enough pulling tension on it.

Swapping it out wasn't a real picnic.  IIRC I removed the drivers coil
and a few other goodies to get my hands down in there.  There is the
connector for the switch that is tucked under the floor mat (follow
the 2 brown wires that come through the hole in the firewall created
for the accelerator cable).

There is a possibility that the throttle cable is out of adjustment
and it is not the kick down switch, but I would guess that that the
other route is more likely.

Cheers,

- Jeremy

 I have two 3.6L 90V8Qs.  One has the original 90 4spd automatic and the
 other has a 93 4spd automatic.  The  90 tranny drops down one or two speeds
 when I floor it and gives me the power I need for merging onto the
 interstate, etc.  The 93 tranny doesn't behave the same way and fails to
 drop down more than one gear beyond 65mph when I floor it--feels more like
 a 4cyl. between 65 and 75mph.  Questions:  What governs the kickdown points
 on these transmissions?  There isn't a kickdown switch per se. Were there
 design modifications to the 93 trannies (or other 4.2L automatics) that
 would cause them to function differently when connected up to a 3.6L?
