AUTOMATIC TRANSMISSION 5A-23
SSANGYONG Y200
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.
Control
To maintain this arrangement in the steady state sole-
noids 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.
