Replacement
Disconnect the speed sensor connectors, then re-
move the harness clamp on the countershatt speed
sensor harness from the harness stay.
Remove the 6 mm bolts securing the mainshaft and
countershalt speed sensors from the transmission
housrng.
Remove the mainshaft and countershaft speed
sensors,
Installthe mainshatt and countershalt speed sensors

Road Test
NOTE: Warm up the engine to operating temperature (the cooling fan comes on).
1 Apply parking brake and block th€ wheels. Start the engine, them move the selector lever to E] position whiledepressing the brake pedal. Depress the accelerator pedal, and release it suddenly. The engine should not stall,
2. Repeat same test in @ position.
3. Shift the selecto. lever to E position, and chock that the shift points occur at approximate speeds shown. Alsocheck fof abnormal noise and clutch slippage.
NOTE: Throttle position sensor voltage fepresents the throttle opening.
- 1 . Connect the Test Harness between the ECM and connector (see section 1 1).-2. Setthe digital multimeter to check voltage between D1 1{+)terminal and D22 { - ) terminal for the throttle Dosi-tion sensor.

4. Accelerate to about 35 mph {57 km/h) so the transmission is in 4th, then shift from @ Oosition to E position.
The car should immediately begin slowing down from engine braking.
CAUTION: Do not shift from @ or @ position to @ of E position at speeds over 1OO mph (160 km/h); you
may damage the tlansmission,
5. Check lor abnormal noise and clutch slippage in the following positions.
E (1st Gear) Position- 1 . Accelerate from a stop at full throttle. Check that there is no abno.mal noise or clutch slippage.
-2. Upshifts should not occur with the selector in this position
E (2nd cear) Position.- 1 . Accelerate from a stop at full throttle. Check that there is no abnormal noise or clutch slippage.-2. Upshitts and downshitts should not occur with the selector 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 {Parking) Position
Park car on slope (approx. 1 6o ), apply the parking brake, and shift into LE position. Release the brake; the car should
not move.
