The 2-4 clutch is one of two clutches located in
the rear portion of the transaxle case. This clutch
sits behind the input clutch assembly. The 2-4 clutch/
piston retainer is in the front and held in place by
a snap ring. The 2-4 piston is located inside the
b
2-4 clutch/piston retainer. A belleville spring is used
to return the piston after releasing the clutch. The
clutch pack comes next in the case. The reaction
plate is secured to the case using two snap rings.
The reaction plate for the 2-4 clutch is shared with
the Low Reverse clutch. When the 2-4 clutch is
applied hydraulically, it locks or secures the front
sun gear/hub assembly to the case so it does not
turn.
To apply the 2-4 clutch, line pressure is sent from
the valve body straight into the piston retainer. The
valve body has a rubber seal located on the top
of it that seals the valve body to the piston retainer.
When line pressure is removed and vented,
th
belleville spring returns the
p’iston
to release th
1
clutch.
