my Ford F-150 12th Generation (2009-2014) transmission fluid smells burnt, what now?

Solution

1. Preparation

• Gather tools and parts.
• Ensure the vehicle is parked on a level surface and the engine is cool.
• Disconnect the negative battery terminal to prevent any electrical issues.

2. Drain Old Transmission Fluid

• Place a drain pan under the transmission pan.
• Remove the transmission pan bolts using a socket set.
• Carefully lower the pan to drain the old fluid and inspect for metal shavings or debris.
• Clean the transmission pan and magnet (if equipped) thoroughly.

3. Replace Transmission Filter

• Remove the old transmission filter by unscrewing or unclipping it.
• Install the new transmission filter, ensuring it is seated properly.
• Apply a thin layer of transmission fluid to the rubber O-ring of the new filter.

4. Install Transmission Pan

• Apply a new gasket or sealant to the transmission pan.
• Reattach the transmission pan to the transmission case, tightening the bolts to the manufacturer's specified torque (typically around 10-12 ft-lbs for most applications).
• Ensure the pan is secure and leak-free.

5. Refill Transmission Fluid

• Using a funnel, refill the transmission with the appropriate type and amount of new transmission fluid (consult the owner's manual for specifications, typically Mercon LV fluid for this generation).
• Start the engine and let it idle for a few minutes while checking for leaks.
• Shift through all gears with the vehicle stationary to circulate the fluid, then check the fluid level again and top off as necessary.
