4. Accelerate to about 35 mph (57 km/h) so the transmission is in 4th, then shift from position to position. The vehi-

cle should immediately begin slowing down from engine braking.

CAUTION: Do not shift from or position to or position at speeds over 63 mph (100 km/h); you may dam-

age the transmission.

5. Check for abnormal noise and clutch slippage in the following positions.

(1st Gear) Position

a. Accelerate from a stop at full throttle. Check that there is no abnormal noise or clutch slippage,

b. Upshifts should not occur with the shift lever in this position.

(2nd Gear) Position

a. Accelerate from a stop at full throttle. Check that there is no abnormal noise or clutch slippage,

b. Upshifts and downshifts should not occur with the shift lever in this position.

(Reverse) Position

Accelerate from a stop at full throttle, and check for abnormal noise and clutch slippage.

6. Test in (Parking) Position

Park the vehicle on slope (approx. 16°), apply the parking brake, and shift into position. Release the brake; the vehi-

cle should not move.ProCarManuals.com

Stall Speed

Test

CAUTION:

To prevent transmission damage, do not test stall speed for more than 10 seconds at a time.

Do not shift the lever while raising the engine speed.

Be sure to remove the pressure gauge before testing stall speed.

1. Engage the parking brake, and block the front wheels.

2. Connect a tachometer to the engine, and start the engine.

3. Make sure the A/C switch is OFF.

4. After the engine has warmed up to normal operating temperature (the radiator fan comes on), shift into [2] position.

5. Fully depress the brake pedal and accelerator for 6 to 8 seconds, and note engine speed.

6. Allow two minutes for cooling, then repeat the test in , , and positions.

NOTE:

• Stall speed tests should be used for diagnostic purposes only.

• Stall speed should be the same in , and positions.

Stall Speed RPM:

Specification: 2,000 rpm

Service Limit: 1,850 - 2,150 rpmProCarManuals.com

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.
