Pressure Testing — '96 Model

3. Slowly depress the accelerator pedal to increase

engine rpm until pressure is indicated on the pres-

sure gauge. Then release the accelerator pedal,

allowing the engine return to an idle, and measure

the pressure reading.
4. With the engine idling, depress the accelerator

pedal approximately 1/2 of its possible travel, and

increase the engine rpm until pressure is indicated

on the gauge. Then measure the highest pressure

reading obtained.

5. Repeat steps 3 and 4 for each clutch pressure being

inspected.

Throttle B Pressure Measurement

While testing, be careful of the rotating

front wheels.

1. Disconnect the transmission sub-harness connector

(14P).

2. Start the engine, and run it at 1,000 rpm.

3. Measure fully-opened throttle B pressure.

4. Connect battery voltage to the linear solenoid termi-

nals of the transmission sub-harness connector as

shown.

Installation

1. Flush the ATF cooler (see flushing procedure in the

'95 - '98 Acura 2.5TL Service Manual, 61SW504).

2. Install the torque converter securely with a new O-ring

on the mainshaft, and install two 14 x 20 mm dowel

pins in the torque converter housing.

7. Attach the torque converter to the drive plate with

six bolts and torque:

Rotate the crankshaft as necessary to tighten the

bolts to 1/2 of the specified torque, then to the final

torque, in a crisscross pattern. After tightening the

last bolt, check that the crankshaft rotates freely.

8. Install the torque converter covers.

9. Install the engine stiffener. Tighten the engine stiff-

ener 8 mm bolts loosely, and tighten the transmis-

sion housing mounting bolt to the specified torque,

then tighten the 8 mm bolts to the specified torque.
