(1) Power flow - Reverse
In Reverse, transmission drive is via the input shaft and the forward clutch cylinder to the hub of
the C3 clutch.
The elements of the transmission function as follows :
- The C3 clutch is engaged and drives the reverse sun gear in a clock-wise direction.
- The B2 band is engaged and holds the planetary gear carrier stationary causing the long
pinion to rotate anti-clockwise about its axis on the pinion shaft.
- The long pinion drives the internal ring gear in the same direction.
- The internal ring being splined to the output shaft drives it in an anti-clockwise or reverse
direction.
(2) Control
To maintain this arrangement in the steady state solenoids and valves are activated as
follows :
- Solenoids S1 and S2 are switched OFF.
- Line pressure is directed through the reverse lockout valve to both the inner and outer
apply areas of the rear servo piston for B2 band application.
- Line pressure feeds the reverse oil circuit via the manual valve.
- Reverse oil is routed from the manual valve to the C3 clutch.
- Reverse oil is also applied to the spring end of the primary regulator valve to assist the
spring and to boost the line pressure value.
- All other clutch and band apply circuits are open to exhaust.
