4. Accelerate to about 35 mph (57 km/h) so the transmission is in 4th, then shitt from E position to E position.
The vehicle should immediately begin slowing down from engine braking.
CAUTION: Do noi shitt lrom I or $ position to E or E position 8t speeds over l0o mph (160 km/h); you may
damage the transmission.
5. Check for abnormal noise and clutch slippage in the following positions,
E {1st Gear} Position-1. Accelerate from a stop at fullthrottle. Check that there is no abnormal noise or clutch slippage.-2. Upshifts should not occur with the shift lever in this position.
E (2nd Gear) Position-1. Accelerate from a stop atfull throttle. Check that there is noabnormal noiseorclutch slippage.-2. Upshifts and downshifts should not occur with the shift lever in this position.
E (Reverse) Position
Accelerate from a stop at tull throttle, and check for abnormal noise and clutch slippage.
6. Test in E (Parking) Position
Park vehicle on slope {app.ox. 16'}, apply the parking brake, and shift into E position. Release the brake; the vehicle
should not move.

a Make sule litts, iacks, and safety stands are placed
properly (see section 1).
CAUTION: Befoie testing, be sure the transmission fluid
is filled to the proper level.
'1. Raise the vehicle {see section 'll.
2. Warm up the engine (the radiator fan comes on),
then stop the engine and connect a tachometer.
3. Connect the special tool to each inspection hole(s).

5. Slowly move the throttle linkage to increase engine
rpm until pressure is indicated on the A/T pressure
gauge.
Then release the throttle linkage, allowing the en-
gine to return to an idle, and measure the pressure
reading.
6. With the engine idling. lift the throttle controldrum
up approximately 'l12 of its possible travel and in-
crease the engine rpm until pressure is indicated
on the gauge, then measure the highest pressure
reading obtained.
