Transmission Speed Sensor: Service and Repair
SPEED SENSORCOMPONENTS:
REMOVAL
1. REMOVE COWL TOP VENTILATOR LOUVER
2. DISCONNECT CABLE FROM NEGATIVE BATTERY TERMINAL
CAUTION: Wait at least 90 seconds after disconnecting the cable from the negative (-) battery terminal to prevent airbag and seat belt pretensioner activation.
NOTICE: After the engine switch is turned off, the HDD navigation system requires approximately 6 minutes to record various types of memory and settings. As a result, after turning the engine switch off, wait 6 minutes or more before disconnecting the cable from the negative (-) battery terminal.
3. DRAIN AUTOMATIC TRANSMISSION FLUID
(a) Remove the drain plug and gasket, and drain the ATF.
(b) Install a new gasket and the drain plug.
Torque: 20 N*m (204 kgf*cm, 15 ft.*lbf)
4. REMOVE AUTOMATIC TRANSMISSION OIL PAN SUB-ASSEMBLY
(a) Remove the 9 bolts, oil pan and gasket from the transmission.
NOTICE: Some fluid will remain in the oil pan. Remove all the pan bolts, and carefully remove the oil pan assembly.
(b) Remove the 3 transmission oil cleaner magnets from the oil pan.
(c) Examine the particles in the pan.
(1) Collect any steel chips with the removed magnets. Carefully look at the foreign objects and particles in the pan and on the magnets to guess the type of wear which might be found in the transmission.
Steel (magnetic): bearing, gear and clutch plate wear
Brass (nonmagnetic): bush wear
