why does my Ford F-150 Fourteenth Generation (2021-present) smell like burning transmission fluid

Solution

1. Preparation

• Tools Required: Socket set, torque wrench, OBD-II scanner, transmission fluid temperature gauge, container for fluid catch.
• Park the vehicle on a flat surface and engage the parking brake.
• Disconnect the battery to ensure safety during maintenance.

2. Check and Replace Transmission Fluid

• Sub-steps:
  1. Remove the transmission dipstick and check fluid level and condition (should be reddish and not burnt).
  2. If fluid appears burnt or is below the recommended level, drain the old fluid into a container.
  3. Replace the transmission fluid with the manufacturer's recommended type (e.g., Mercon LV for most Ford transmissions).
  4. Reinsert the dipstick and check the fluid level after adding new fluid.

3. Inspect and Repair Leak Sources

• Sub-steps:
  1. Identify any leaks by inspecting the transmission pan, cooler lines, and seals.
  2. Tighten any loose bolts on the transmission pan if applicable.
  3. Replace any damaged transmission cooler lines or seals.
  4. Refill the transmission fluid if any was lost during the repair process.

4. Transmission System Check

• Sub-steps:
  1. Reconnect the battery.
  2. Start the vehicle and allow it to reach operating temperature.
  3. Use an OBD-II scanner to check for any active error codes related to the transmission.
