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

Solution

1. Preparation

• Gather all necessary tools and parts.
• Disconnect the negative battery terminal to prevent electrical shorts.
• Ensure the vehicle is on a level surface and secure it with wheel chocks.

2. Check and Replace Transmission Fluid

• Sub-steps:
  1. Locate the transmission dipstick (if applicable) or the fill port.
  2. Remove the dipstick or fill plug and check the fluid level; add fluid if low.
  3. If the fluid is discolored or burnt, proceed to change the fluid.
  4. Drain the old transmission fluid by removing the drain plug (if equipped).
  5. Replace the drain plug (torque to manufacturer specifications).
  6. Refill with new, manufacturer-recommended transmission fluid through the fill port.
  7. Start the engine and cycle through the gears to circulate the new fluid, then recheck the level.

3. Inspect and Replace Transmission Mounts (if necessary)

• Sub-steps:
  1. Raise the vehicle safely using jack stands.
  2. Inspect the transmission mounts for cracks or deterioration.
  3. If damaged, remove the bolts securing the old mounts and replace them with new mounts.
  4. Torque the new mounts to the manufacturer's specifications.

4. Update Transmission Control Module (if applicable)

• Sub-steps:
  1. Reconnect the negative battery terminal.
  2. Use a compatible scan tool to check for TCM updates.
  3. Follow the manufacturer's instructions to perform the update, if necessary.

5. Recheck and Secure Electrical Connections

• Sub-steps:
  1. Inspect all electrical connectors to the transmission for corrosion or looseness.
  2. Clean and secure any loose connections.
  3. Test the connections with a multimeter to ensure proper voltage and continuity.
