1994 HONDA INTEGRA clutch

In [Q! or l!31 position. the optimum gear is automatically selected from 1st, 2nd, 3rd and 4th speeds, according to con-
ditions such as the balance between throttle opening (engine load) and vehicle speed.
D! or lE.l Position, lst speed
1. Hydraulic pressure is applied to the lst clutch. which rotates together with the mainshaft, and the mainshaft lst
gear rorares.
2. Power is transmitted to the countershaft 1st gear, and drives the countershaft via the one-way clutch.
3. Power is transmitted to the final drive gear and drives the final driven gear.
NOTE:
In lDil or [Dl]l position, hydraulic pressure is not applied to the 1st-hold clutch.

1. Hydraulic pressure is applied to the 2nd clutch, which rotates together with the mainshaft, and the mainshatt 2nd
gear rotates.
2. Power is transmitted to the countershaft 2nd gear, and drives the countershaft.
3. Power is transmitted to the tinal drive gear and drives the final driven gear.
NOTE:
In @ or @ position, 2nd speed, hydraulic pressure is also applied to the lst clutch. but since the rotation speed
of 2nd gear exceeds that of 1st gear. power trom lst gear is cut off at the one-way clutch.

1. Hydraulic pressure is swilched by the manual valve to the se.vo v8lve, which moves the reverse shilt tork to the
r€verse position. The reverse shiJt fork engages with the reverse selector, reverse selsctor hub,and the countershaft
raverss g€ar.
2. Hydraulic pr6ssure is also appli€d to the 4th clutch. Power is transmifted from the mainshaft reverse gear via the
revetse idler g6ar to the countershaft reverse gear.
3. Rotation dirsction ol the countershsft reverse gear is changed via the .everse idler gear.
4. Powef b transmitted to the linal drive gear and drives the final driven gear.

Hydraulic Control
The valve bodies include the main valve body, secondary valve body, regulator valve body, servo body and lock-up valve
body.
The oil pump is driven by splines behind the torque converter which is attached to the engine. Oil flows th.ough the
regulator valve to maintain specified pressure through the main valve body to the manual valve, directing pressure to
each of the clutches,
