  • •Engine RPMs increasing without corresponding shift
  • •Check engine light may be illuminated
  • •Decreased fuel efficiency
  • •Transmission slipping or failure to engage

Diagnostic Steps

  1. 1Scan the vehicle's OBD-II system for error codes using a diagnostic scanner.
  2. 2Inspect transmission fluid level and condition; top off or replace if necessary.
  3. 3Check for any visible leaks around the transmission or cooler lines.
  4. 4Test the transmission range sensor for proper operation.
  5. 5Inspect the throttle position sensor (TPS) for accurate readings.
  6. 6Evaluate the condition of the transmission filter and solenoids.

Solution

Solution

1. Preparation

  • Gather necessary tools and parts.
  • Ensure the vehicle is parked on a level surface and the engine is off.
  • Disconnect the negative battery cable to prevent electrical short circuits.

2. Check and Replace Transmission Fluid

  • Tools Required: Transmission fluid pump, wrench set, fluid catch pan
  • Sub-steps:
    1. Remove the transmission fluid pan using a socket set.
    2. Allow old fluid to drain completely into the catch pan.
    3. Inspect the transmission filter; replace it if it is clogged or damaged.
    4. Clean the pan with a suitable solvent; replace the gasket.
    5. Reinstall the pan and tighten bolts to the manufacturer’s specified torque.
    6. Refill the transmission with the correct type and amount of fluid as specified in the owner's manual.

3. Inspect and Replace Transmission Range Sensor

  • Tools Required: Socket set, multimeter
  • Sub-steps:
    1. Locate the transmission range sensor on the transmission.
    2. Disconnect the electrical connector from the sensor.
    3. Use a multimeter to check for proper voltage and resistance per the specifications.
    4. If faulty, remove the sensor and install a new one.
    5. Reconnect the electrical connector and ensure secure fitting.

4. Throttle Position Sensor (TPS) Testing and Replacement

  • Tools Required: Multimeter, socket set
  • Sub-steps:
    1. Locate the throttle position sensor connected to the throttle body.
    2. Disconnect the electrical connector and use a multimeter to check the TPS voltage.
    3. Replace the TPS if the readings are outside acceptable ranges.
    4. Reconnect the TPS and clear any codes from the OBD-II system.

Verification

After completing the repair, verify that the issue has been resolved:

  • Test the affected component to ensure it functions correctly
  • Check for any error codes or warning lights
  • Monitor the vehicle for a few days to ensure the issue does not recur
