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.

5. Measure fully-closed throttle B pressure.

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.

Rack Guide Adjustment

NOTE: Perform rack guide adjustment with the wheels

in the straight ahead position.

1. Loosen the rack guide screw locknut with the spe-

cial tool, then loosen the rack guide screw.

3. Retighten the rack guide screw to 3.9 N-m (0.4 kgf-m,

2.9 Ibf-ft), then back it off to the specified angle.

Specified Return Angle: 20 ± 5°

4. Tighten the locknut while holding the rack guide

screw.

5. Check for tight or loose steering through the com-

plete turning travel.

6. Perform the following inspections (refer to the '95 - 98

Acura 2.5TL Service Manual, P/N 61SW504):

• Steering operation.

• Power assist with vehicle parked.ProCarManuals.com

Power Steering Hoses and Pipes

Replacement

NOTE:

• Slide each hose over the corresponding pipe up to

the stop on the pipe. Install the clamp or adjustable

clamp at the specified distance from the hose end as

shown.

• Add the power steering fluid to the specified level on

the reservoir and check for leaks (refer to the '95 - 98

Acura 2.5TL Service Manual, P/N 61SW504).
CAUTION: Check all clamps for deterioration and defor-

mation; replace the clamps with new ones if necessary.

NOTE: Make sure the steering joint is connected as

follows:

a. Insert the upper end of the steering joint onto the

steering shaft (line up the bolt hole with the flat on

the shaft), and loosely install the upper joint bolt,

b. Slip the lower end of the steering joint onto the

pinion shaft (line up the bolt hole with the

groove around the shaft), and loosely install the

lower joint bolt.

Be sure that the lower joint bolt is securely in the

groove in the pinion shaft,

c. Pull on the steering joint to make sure that the

steering joint is fully seated. Then tighten the

joint bolts.
