Road Test
NOTE: Warm up the engine to operating temperature (the radiator fan comes on).
1. Apply parking brake and block the wheels. Start the engine, then shift to @ position while depressing the brake pedal-
Depress the accelerator pedal, and release it suddenly. The engine should not stall.
2. Repeat same test in E position.
3. Test drive the vehicle on a flat road in the @ position. Check that the shift points occur at approximate speeds shown.
Also check for abnormal noise and clutch slippage.
NOTE: Throttle position sensor voltage represents the throttle opening.
-1. Remove the TCM (see page 14-52).-2. Set the digital multimeter to check voltage between 84 (+) terminal and A13 or A26 (-) terminal for the throttle posi-
tion sensor.

Limited Slip Differential (818C5 engine)
Description
t
f1t
1. Function
Operation of the limited slip differential is dependent upon the eight pinion gears that are in mesh with the two sidegears. They transfer the driving power to the driving axles as well as permjt the outside wheel to turn more times thanthe inside wheel when the vehicle goes around a turn. All gears are helically cut so that this differential action is limitedby the friction created between each gear and differential carrier when either wheel slips.
2. Construction
The unit consists of the two side gears, four short pinion gears, four long pinion gears, two thrust washers, a centerwasher, and a carrier that houses the gears and washers. One shon and one long pinion gear are in mesh with eachother and are allowed to walk around the side oears.

The differential carrier and gears rotate together as a unit when both wheels rotates at the same speed. Turningeffon from the final driven gears are directly transmitted to both wheets.

Limited Slip Differential (B18C5 engine)
Description (cont'd)
When roundang a curve
When the vehacle rounds a curye, tne differential allows the outer wheel to rotate a little faster than the inner wheel.
when this takes p|ace. the short and |ong pinion gears rotate, and wa|k around the side gears in the directions
shown. lf, for example. the right shaft is rotated in a counterclockwise direction with the differential carrier held sta-
tionary, the force is transmitted through the right side gear, short pinion gears and long pinion gears to the left side
gear, causing the left shaft to rotate in a clockwise direction. This allows the outer wheel to turn more times than the
inner wheel when the vehicle goes around a turn.
PINION GEARILONG)
When limiting differential action
The limited slip differential acts to limit the differential action when either wheel slips on ice or snow or on turn. This
is done by using the friction created between each gear and differential carrier:"''
(1) The pinions are forced against the differential carrier by the force as they are- rotated and repelled outward.
(2) The ends of the pinion gears are held firmly against the differential carrier due to the side thrust from the heli-
callY cut gears.
CARRIEB
TTFT SHAFT
RIG}IT SHAFT
With the pinion gears locked, the torque applied to the slipping wheel is reduced 8nd the torque delivered to the
other wheel is increased.
