Digital Transmission Range (TR) Sensor: Removal

NOTE: The use of any transmission fluid other than what is recommended for this transaxle will cause transaxle damage. Refer to the MATERIAL  specification and/or the transmission fluid level indicator for the correct fluid. Use only clean transmission fluid designated for this transaxle and torque converter being serviced.
NOTE: Do not mix Mercon® V or Mercon® LV transmission fluid. This may cause erratic shift feel, erratic shift timing and/or transmission failure.
NOTE: Transmission fluid application:
  • Early build vehicles require MERCON® V
  • Late build vehicles require MERCON® LV
  1. With the vehicle in NEUTRAL, position it on a hoist. For additional information, refer to JACKING & LIFTING .
