1995 ACURA TL torque

Description

Position

As the engine turns, the ATF pump also starts to operate. Automatic transmission fluid (ATF) is drawn from (99) and dis-

charged into (1). Then, ATF flowing from the ATF pump becomes the line pressure (1). The line pressure (1) is regulated

by the regulator valve. The torque converter inlet pressure (92) enters (94) of the torque converter through the lock-up

shift valve 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 as the manual valve stops line pressure (1).

NOTE: When used, "left" or "right" indicates direction on the hydraulic circuit.

Position

1. 1st Gear

The flow of fluid through the torque converter circuit is the same as in position.

The line pressure (1) flows to the manual valve, the modulator valve and the throttle valve. The line pressure (1)

becomes modulator pressure (6) at the modulator valve, and remains line pressure (4) at the manual valve.

The modulator pressure (6) flows to the left end of the 1-2 shift valve and right end of the 3-4 shift valve because shift

control solenoid valve A is turned OFF and B is turned ON by the TCM. The 1-2 shift valve is moved to the right side,

and the 3-4 shift valve is moved to the left side.

The line pressure (4) becomes the 1st clutch pressure (10). The 1st clutch pressure (10) is applied to the 1st clutch and

1st accumulator; consequently, the vehicle will move as the engine power is transmitted.

In or position at 1st gear, the 1st-hold clutch pressure is not applied to the 1st-hold clutch because the manual

valve covers the port to leading to the 1st-hold clutch.

Position

The flow of fluid through the torque converter circuit is the same as in position.

The line pressure (1) becomes the line pressure (3) and flows to the 1-2 shift valve.The line pressure (3) becomes line pres-

sure (3') at the 1-2 shift valve and flows to the servo valve. The servo valve is moved to the right side (Reverse range posi-

tion) and uncovers the port to allow line pressure (3") to the manual valve. The line pressure (3') from the 1-2 shift valve

flows through the servo valve to the manual valve and becomes to the 4th clutch pressure (40). The 4th clutch pressure

(40) is applied to the 4th clutch, and the 4th clutch is engaged.

Reverse Inhibitor Control

When the position is selected while the vehicle is moving forward at speeds over 6 mph (10 km/h), the TCM outputs the

1st signal to shift control solenoid valves A and B; shift control solenoid valve A is turned ON, shift control solenoid valve

B is turned OFF. The 1-2 shift valve is moved to the right side and covers the port to stop line pressure (3') to the servo

valve. The line pressure (3') is not applied to the servo valve, and the 4th clutch pressure (40) is not applied to the 4th

clutch, as a result, power is not transmitted to the reverse direction.

Description

B Position

The flow of fluid through the torque converter circuit is the same as in position.

The line pressure (1) becomes the line pressure (3) and flows to the 1-2 shift valve. The line pressure (3) becomes line

pressure (3') at the 1-2 shift valve and flows to the servo valve. The servo valve is moved to the right side (Reverse range

position) and uncovers the port to allow line pressure (3") to the manual valve as in position. The line pressure (3")

from the servo valve is intercepted by the manual valve.

However, hydraulic pressure is not supplied to the clutches, and power is not transmitted.

Set the control shaft to the position, then install

the A/T gear position switch on the control shaft

and install the clamp on the rear cover.

9. Connect the A/T gear position switch connector,

then install the harness stay.

10. Turn the ignition switch ON (II). Move the shift lever

through all gears, and check the A/T gear position

switch synchronization with the A/T gear position

indicator.

11. If the A/T gear position switch does not synchronize

with the A/T gear position indicator, loosen the

bolts securing the A/T gear position switch and

adjust the A/T gear position switch installation.

12. Install the A/T gear position switch cover. Tighten

the bolt on the ATF pan side loosely so that there is

no clearance between the A/T gear position switch

cover and the ATF pan. Then tighten the bolt on the

rear cover side to the specified torque, and tighten

the bolt on the ATF pan side to the specified torque.

13. Start the engine. Move the shift lever through all

gears, and verify the following:

• The shift lever cannot be moved to the posi-

tion from the position without pushing the

shift lever.

• The engine will not start in any gear, only in the

or position.

• The back-up lights come on when the shift lever

is in the position.ProCarManuals.com
