Solution
1. Preparation
  • Gather necessary tools and parts.
  • Park the vehicle on a level surface and engage the parking brake.
  • Disconnect the battery to ensure safety while working on electrical components.
2. Transmission Fluid Change

  • a. Drain Fluid:

    • Place a drain pan under the transmission pan.
    • Remove the transmission pan bolts using a socket set, and carefully lower the pan to drain the fluid.

  • b. Replace Filter:

    • Remove the old transmission filter and replace it with a new one.
    • Ensure the filter is properly seated.

  • c. Install New Gasket:

    • Clean the mating surfaces and install a new gasket on the transmission pan.

  • d. Refill Transmission Fluid:

    • Reinstall the transmission pan and torque the bolts to the manufacturer's specifications.
    • Use a funnel to refill the transmission with the appropriate type and amount of fluid as specified in the owner's manual.
3. Inspect and Replace Faulty Sensors

  • a. Transmission Range Sensor:

    • Disconnect the electrical connector from the transmission range sensor.
    • Remove the sensor and install a new one, ensuring it is properly aligned and secured.

  • b. Transmission Control Module (TCM):

    • Inspect the TCM connections; if damaged, replace the TCM and reprogram it according to manufacturer specifications.
4. Test Drive
