The R4A51 transmission is a fully electronically
controlled rear-drive transmission used in twowheel-
drive applications. The V4A51 is the
four-wheel-drive version. These transmissions are
used in 1999 to 2003 Mitsubishi Montero and
Montero Sport SUVs behind the 3.0- or 3.5-liter
SOHC engines.
This transmission uses all clutches and no bands
to attain the four forward speeds and reverse. These
transmissions, from the start of production, have a
low one-way clutch (sprag). The structure of this
transmission allows for an easy transformation into a
five-speed unit.
In this first of a two-part Technical Supplement,
Mitsubishi Montero/Sport
R4A51/V4A51
basic assembly tips and internal-component identification
will be the subject matter, beginning with information
such as a clutch-application chart,
hydraulic-pressure tests and some basic electrical
items such as case-connector-terminal identification,
resistance values and solenoid ID and continuing
with assembly tips.
The order of assembly begins from the rear of the
transmission, eventually working our way toward
the front and finally the valve body.
Part 2 will contain further assembly tips as well as
valve-body information and other items important to
rebuild technicians.
