ATF pump worn or binding
Mainshaft bearing, countershaft
bearing, or secondary shaft
bearing defective Improper alignment of ATF pump and torque
converter housing may cause ATF pump seizure.
The symptoms are mostly an rpm-related ticking
noise or a high pitched squeak.
Be careful not to damage the torque converter
housing when replacing the main ball bearing.
You may also damage the ATF pump when you
torque down the main valve body. This will result
in ATF pump seizure if not detected. Use the
proper tools.
Install the main seal flush with the torque
converter housing. If you push it into the torque
converter housing until it bottoms out, it will
block the fluid return passage and result in
damage.
Inspect the ATF strainer is clogged with particles
of steel or aluminum. If the ATF strainer is
clogged, replace it, and clean the torque
converter, cooler, and lines.
Inspect the mainshaft, the countershaft, and the
secondary shaft for wear or damage.

NOTE: Do not use a hammer as excessive force
may damage the driveshaft. Be careful not to
damage the threaded section (A) of the outboard

8. Check the alignment of the paint mark (A) you made with the outboard joint end (B).
To avoid driveshaft and vehicle damage, the
shaft must be all the way into the outboard
joint to ensure the stop ring is properly
seated. 9. Pack the outboard joint (A) with the remaining
grease included in the new outboard boot set.
10. Fit the boot ends (A) onto the driveshaft (B) and outboard joint (C). Bleed any excess air from the
boot by inserting a flat-tipped screwdriver between
the boot and the joint.
Use the grease included
in the outboard boot set.

1. Turn the brake pedal position switch (A) counterclockwise, and pull it back until it is no
longer touching the brake pedal.
2. Pull back the carpet, and find the cutout in the insulation. Measure the pedal height (B) at the
middle of the left side center of the pedal pad (C) to
the floor without the insulation. 3. Loosen the pushrod locknut (A), and screw the
pushrod (B) in or out with pliers until the standard

adjustment, tighten the locknut firmly. Do not
adjust the pedal height with the pushrod pressed.
4. Lift up on the brake pedal by hand. Push in the brake pedal position switch until its plunger is fully
pressed (threaded end (A) touching the pad (B) on
the pedal arm). Turn the switch 45 ° clockwise to

Functional Test

Brake Booster Test
A
1. With the ignition switch in LOCK (0), press the
brake pedal several times to deplete the vacuum
reservoir, then press the brake pedal hard, and hold
it for 15 seconds. If the brake pedal sinks, either the
master cylinder is bypassing internally, or the
brake system is leaking. Inspect the brake hoses
and lines (see page 19-37).
2. Start the engine with the brake pedal pressed. If the brake pedal sinks slightly, the vacuum booster is
operating normally. If the brake pedal height does
not vary, do the brake system test (see page 19-4).
1. Press the brake pedal with the engine running, then stop the engine. The brake pedal height should not
vary while pressed for 30 seconds.
If the pedal height rises, go to step 6.
If it does not rise, go to step 2.
2. Start the engine and let it idle for 30 seconds. Turn the ignition switch to LOCK (0), and wait
30 seconds. Press the brake pedal s everal times
using normal pressure. When the pedal is first
pressed, it should be low. On consecutive
applications, the pedal height should gradually rise.
Does the pedal rise on each consecutive
application?
If it rises the booster is OK.
If it does not rise, go to step 3. 3. Disconnect the brake booster vacuum hose (A) at
the booster. The check valve is built into the hose.
NOTE: If the check valve is faulty, replace the brake
booster vacuum hose/check valve as an assembly.
4. Start the engine, and let it idle. There should be vacuum available.
If no vacuum is available, the check valve is not working properly. Replace the brake booster
vacuum hose and check valve, and retest.
Ifthereisvacuum,gotostep5.
5. With the ignition switch in LOCK (0), reconnect the vacuum hose to the brake booster.
6. Start the engine, and then pinch the brake booster vacuum hose between the check valve and the
booster.
7. Turn the ignition switch to LOCK (0), and wait 30 seconds. Press the brake pedal several times
using normal pressure. When the pedal is first
pressed, it should be low. On consecutive
applications, the pedal height should gradually rise.
If the pedal position does not vary inspect the seal between the master cylinder and booster. If
the seal is OK, replace the brake booster.
If the pedal position varies, replace the brake booster vacuum hose/check valve as an
assembly.

7. Pull the brake booster (A) forward.
Be careful not to damage the brakebooster mounting surfaces and the
threads on the booster studs.
Be careful not to bend or damage the brake lines.
8. Remove the brake booster by pu lling it out and
turning it, and remove it from the engine
compartment.
NOTE: Use a new brake booster gasket (B) during
reassembly. 9. Install the brake booster in the reverse order of
removal, and note these items:
Install the master cylinder after installing the brake booster (see page 19-24).
Replace the master cylinder rod seal.
Check the brake pedal height and free play after installing the master cylinder, and adjust it if
necessary (see page 19-6).
Bleed the brake system (see page 19-9).
