Manual valve
▶
The manual valve is connected to the
vehicle selector mechanism and controls the
flow of oil to the forward and reverse
circuits. The manual valve function is
identical in all forward gear positions except
that in the Manual 1 position an additional
supply of oil is directed to the 1- 2 shift valve
for application of the rear band and the C4
overrun clutch. The manual valve directs the
line pressure into the PRND fluid circuits.
1-2 shift valve
▶
The 1-2 shift valve is a two position valve
that must be switched to the 2, 3 and 4
position in order to get any forward gear
other than first gear. It is used for all 1-2 and
2-1 gearshifts.
The switching of this valve is achieved by
using S1 and/ or S2.
During a 1-2 gearshift drive oil from the
manual valve passes through to the second
gear circuit. During a 2-1 gearshift the band
apply feed oil is allowed to exhaust via the
1-2 shift valve.
The 1-2 shift valve works in conjunction with
the 3-4 shift valve to disengage the C4
clutch in first gear, and engage C4 in second
gear. When Manual 1 is selected the C4
clutch and rear band (B2) are engaged.
