It has all the features in
the Shift Improver Kit plus
it provides additional driver
manual control. Most stock
automatic transmissions won't
downshift into low gear above
15 mph, and automatically
upshift at a predetermined
speed no matter what gear
you're in. With the Transpak,
you can downshift at any
speed, and you can hold the
transmission in first gear to
any speed that you want! This
is an asset when you've got a
modified engine, and you want
additional RPMs, or you're
towing a trailer or driving
heavy loads downhill.
