why does my Ford Mustang S650 (2024-Present) transmission slip when shifting

Solution

1. Preparation

• Gather tools and materials.
• Ensure the vehicle is on a level surface and securely raised with jack stands.
• Disconnect the battery to prevent electrical shorts.

2. Inspect and Replace Transmission Fluid

• Sub-steps:
  1. Locate the transmission dipstick or fill port.
  2. Remove the dipstick and check fluid level; add fluid if low.
  3. If fluid is dark or has a burnt smell, drain the old fluid using a fluid pump.
  4. Replace the transmission pan gasket and filter if applicable.
  5. Refill with manufacturer-recommended transmission fluid until proper level is achieved.

3. Inspect Transmission Linkage

• Sub-steps:
  1. Visually inspect the transmission linkage for any signs of wear or disconnection.
  2. Adjust the linkage as necessary to ensure proper engagement.
  3. Tighten any loose bolts or fittings.

4. Check Torque Converter Function

• Sub-steps:
  1. Start the engine and allow it to reach operating temperature.
  2. With the vehicle in gear, observe the RPMs and check for proper engagement of the torque converter.
  3. If it is not locking up, the torque converter may need replacement.

5. Reconnect Battery and Test Drive

• Sub-steps:
  1. Reconnect the battery terminals.
  2. Perform a test drive to confirm the issue is resolved.
  3. Monitor for any signs of slipping or abnormal behavior.
