Back to Generation
1. Delayed or Sluggish Shifting
  • Description: The vehicle may hesitate or take longer to engage gears when accelerating.
  • Reason: Insufficient fluid pressure generated by a failing pump can delay gear engagement.
2. Warning Lights
  • Description: The Check Engine Light or Transmission Fluid Temperature warning light may illuminate on the dashboard.
  • Reason: The vehicle's computer detects abnormal transmission performance or low fluid pressure.
3. Unusual Noises
  • Description: You may hear whining, grinding, or growling noises coming from the transmission area.
  • Reason: Insufficient lubrication and pressure can cause internal components to grind or rub against each other.
4. Overheating
  • Description: The transmission may overheat, leading to a burning smell or increased operating temperatures.
  • Reason: A failing pump may not circulate fluid effectively, leading to poor cooling.
5. Fluid Leaks
  • Description: Transmission fluid may leak under the vehicle, typically brown or red in color.
  • Reason: A failing pump can cause seals to wear out, leading to leaks.
6. Erratic Shifting
  • Description: The transmission may shift unexpectedly or slip in and out of gear.
  • Reason: Insufficient hydraulic pressure affects the clutch engagement and gear selection.
Tools Required
  • OBD-II Scanner
  • Transmission Fluid Pressure Gauge
  • Basic Hand Tools (sockets, wrenches, screwdrivers)
  • Fluid Catch Pan
  • Safety Glasses
  • Mechanic’s Gloves
Step-by-Step Diagnostics

  1. Visual Inspection

    • Check for any visible transmission fluid leaks under the vehicle.
    • Inspect the transmission fluid level using the dipstick. If low, top off with the recommended fluid.

  2. Scan for Codes

    • Use an OBD-II scanner to check for any diagnostic trouble codes (DTC) related to the transmission.
    • Note any codes, especially those related to fluid pressure or shifting issues.

  3. Check Fluid Condition

    • Remove the transmission dipstick and inspect the fluid for color and smell. It should be bright red and have a sweet smell.
    • Dark, burnt, or contaminated fluid indicates potential internal issues.

  4. Pressure Test

    • Attach a transmission fluid pressure gauge to the test port (if available).
    • Start the engine and allow it to idle. Check the pressure readings against the manufacturer specifications.
    • A low pressure reading can indicate a failing pump.

  5. Road Test

    • Drive the vehicle and monitor for any symptoms like slipping, delayed shifting, or strange noises.
Repair Instructions
Tools & Materials Required
  • Replacement Transmission Fluid Pump
  • Transmission Fluid (as specified by manufacturer)
  • Gasket or Sealant (if required)
  • Basic Hand Tools (sockets, wrenches, screwdrivers)
  • Torque Wrench
  • Fluid Catch Pan
Step-by-Step Repair

  1. Safety First

    • Park the vehicle on a level surface, engage the parking brake, and disconnect the negative battery terminal.

  2. Drain Transmission Fluid

    • Place a fluid catch pan under the transmission pan.
    • Remove the transmission pan bolts and carefully lower the pan to drain fluid.

  3. Remove Transmission Pan

    • Clean the pan and remove the old gasket material if applicable.

  4. Access the Pump

    • Depending on the design, you may need to remove the valve body or other components to reach the pump.
    • Carefully label and remove any connectors or hoses.

  5. Remove the Old Pump

    • Unscrew the bolts securing the transmission fluid pump.
    • Gently pull out the old pump; be cautious of any remaining fluid.

  6. Install the New Pump

    • Position the new pump in place and secure it with bolts, ensuring all are tightened to the manufacturer's torque specifications.

  7. Reassemble Components

    • Reinstall any components removed to access the pump, following the reverse order of removal.
    • Ensure all connectors and hoses are securely reattached.

  8. Refill Transmission Fluid

    • Reinstall the transmission pan with a new gasket or sealant.
    • Refill the transmission with the recommended fluid through the dipstick tube.

  9. Check for Leaks

    • Reconnect the negative battery terminal and start the engine.
    • Allow the engine to warm up and check for any leaks around the transmission pan and pump area.

  10. Test Drive

    • Take the vehicle for a test drive to ensure proper operation. Monitor shifting and listen for any unusual noises.

By following these steps, you can diagnose and repair a failing transmission fluid pump in your 2019 Toyota Camry (XV70). Always consult the vehicle's service manual for specific torque settings and fluid specifications.
