W
hat is it about the 450-43LE
that’s so intriguing? Well,
let’s see: There are no
checkball locations to be found in any
shop manual, no disassembly proce-
dures, no valve body exploded views,
and no definite identifying hydraulics.
Need I say more? After numerous calls
to the ATRA HelpLine on this unit, it
was apparent we needed to get one here
and dissect it to the core, and thanks to
Dalyn and the guys at WIT (WHAT-
EVER IT TAKES) we got one.
In this first of a two-part series of
Figure 1 Let’s Play Ball, we’ll identify the trans-
mission case, valve body, and wiring.
We’ll start with the application of the
transmission.

Valve Body
The 450-43LE valve
body can be identified by its
size alone. The upper valve
body has nine checkballs
and one filter (figure 4). The
lower valve body has two
checkballs that are used for
the cooler and one check
valve cup used for pressure
