Automatic HONDA INTEGRA 1994 4.G Owner's Guide

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.

. Ascending Contlol
When the TCM determines that the vehicle is climbing a hill in @ position, the system extends the engagement area
of 3rd gear to prevent the transmission Irom frequenrly shitting between 3rd and 4th gears, so the vehicle can run smooth
and have more power when needed.
NOTE: Shift schedules between 3rd and 4th gear are stored in the TCM to enable the transmission to automatically
select the most suitable gear according to the magnitude of a gradient by Fuzzy logic.
. Descending Control
When the TCM determines that the vehicle is going down a hill in @ position. the shift-up speed from 3rd to 4th gear
when the throttle is closed becomes taster than the set speed for tlat road driving to widen the 3rd gear driving area.
This, in combination with engine brake from the deceleration lock-up, achieves smooth driving when the vehicle is
descending.
There are two ascending modes with different 3rd gear driving areas according to the magnitude of a gradient stored in
the TCM.
When the vehicle is in 4th gear, and you are decelerating on a gradual hill, or when you are applying the brakes on a
steep hill, the transmission will downshitt to 3rd gear. When you accelerate the transmission will then return to 4th gear.

. Deceleration Control
Vohicle SDood
When the vehicle goes around a corner, and needs to decelerate first and then accelerate, the TCM sets the data for
deceleration control to reduce the number of times the transmission shifts to obtain smooth driving. When the vehicle
is decelerating from speeds above 27 mph (43 km/h). the TCM shifts the transmission from 4th to 3rd earlier than normal
to cope with upcoming acceleration to maintain smooth driving.
NOTE:
Fuzzy Logic: Fuzzy logic is a from at artificial intelligence that lets computers respond to changing conditions much like
a human mind would.

E Position
As the engine turns, the oil pump also starts to operate. Automatic transmission fluid (ATF) is drawn from (99) and dis-
charged into (1 ). Then, ATF pressure is controlled by the regulator valve and becomes line pressure ( 1 ). The torque con-
verter inlet pressure (92) enters (94) of torque converter through the orifice and discharges into {90}.
The torque converter check valve prevents the torque converter pressure from rising'
Under this condition, the hydraulic pressure is not applied to the clutches.

Checking
NOTE: Check the fluid level with the engine at normal
operating temperature (the cooling lan comes on).
1. Park the car on level ground. Shut otf the engine.
2. Remove the dipstick (yellow loop) from the trans-
mission, and wipe it with a clean cloth.
3. Insert the dipstick into the transmission.

1. Bring the transmission up to operating temperature
by driving the car. Park the car on level ground, turn
the engine oft, then remove drain plug.
NOTE: lf a cooler flusher is to be used, see page
14-168 and 169.
2. Reinstail the drain plug with a new sealing washer,
then refillthe transmission to the upper mark on the
dipstick.

4. Check that the hole in the adiuste. in perfectly
aligned with the hole in the shift cable. There are two
holes in the end of the shitt cable, They are posi-

shift cable and adjust as required.
6. Tighten the locknut to 7 N.m (O.7 kgf.m, 5lbf.ft).
7. Install the lock pin on the adiuster. lf you feel the
lock pin binding as you reinstall it, the cable is still
out of adjustment and must be readjusted.
8. Move the selector to each gear and verify that the
automatic transaxle gear position indicator tollows
the automatic transaxle gear position switch.
9. Start the engine and check the shift lever in all gea.s.
lf any gea. does not work properly, refer to
troubleshooting on page 14-86 thru 89.

shift indicator panel, ve.ify that the shift lock lever
is released,
