lgrr or E Position:
Upshift
NOTE:
. Lock-upON:The lock-up control solenoid valve A turns ON.. Lock-up OFF: The lock-up control solenoid valve A turns OFF.
4. Accelerate to about 35 mph (57 km/h) so the transmission is in 4th. then shift from E or E position to E position.The vehicle should immediately begin slowing down from engine braking.
5. Check for abnormal noise and clutch slippage in the following positions.
E {1st Gear) Position
Accelerate from a stop at full throttle, Make sure there is no abnormal noise or clutch slippage.Upshifts should not occur with the shift lever in this position.
E (2nd cear) Position
Accelerate from a stop at fuI throttre. Make sure there is no abnormar noise or crutch srippage.Upshifts and downshifts should not occur with the shift lever in this position.
E (Reverse) Position
Accelerate from a stop at full throttle. and check for abnormal noise and clutch slippage.
6. Test in E (Park) Position
Park the vehicle on slope (approx. 16"), apply the parking brake, and shift into E position. Release the brake; the vehi-cle should not move.

Stall Speed
Test
CAUTION:
. To prevent transmission damage, do not te3t stall speed for mors than 10 s€€onds at a time'
. Do not shift the lever while raising th€ engine spsed.
. Be sure to remove tho pressuro gauge bofore testing stall speed,
1. Before testing, check the transmission fluid level, s€e page 14-160.
2. Engage the parking brake and block all four wheels
3. Connect the tachometer, and start the engane.
4. Make sure the Ay'C switch is OFF
5. After the engine haswarmed upto normal operating temperature (the radiator fan comes on),shiftinto@ position.
6. Fully press the brake pedal and accelerator for 6 to 8 seconds, and note engine speed '
j. A|ow 2 minutes for cooling, then repeat the test in E, E ('97 - 98). E {'99 - 00}, and E positions. Stall speed should
be the same in E, E, E, tr. and E positions
Stall Speed rpm:

Mako sure lifts, iacks, and safety stands ar€ placed
properly (see scction 11.
Before testing, be sure the transmission fluid is
filled to the proPer level.
4WD:
Raise the vehicle (see section 11.
2WD:
Raise the front of the vehicle, and make sure it is
securely supported. Set the parking brake, and block
both rear wheels securely.
Allow all four wheels {4WD) or front wheels (2wD}
to rotate freely.
Warm up the engine (the radiator fan comes on),
then stop it and connect the tachometer.
Connect the oil pressure gauges to each inspection
hole securely, and do not allow dust or other foreign
particles to enter the inspection holes.
