Automatic Transmission Components for 2018–2021 Ford F-150 3.0L Power Stroke

The 3.0L Power Stroke diesel gave the Ford F-150 a perfect balance of power, torque, and efficiency — but keeping the automatic transmission in top shape is essential for long-term reliability. Whether you use your truck for towing, daily driving, or off-road adventures, proper maintenance and strategic upgrades will help your transmission run cooler, shift smoother, and last longer.

The 10-speed automatic paired with the 3.0L Power Stroke is a sophisticated transmission designed for both performance and fuel efficiency. However, heat remains the biggest enemy of any transmission. Installing an auxiliary transmission cooler or upgrading to a high-efficiency universal cooler helps regulate fluid temperature, reduce thermal stress, and extend service intervals.

For fluid protection and performance, using premium transmission fluid ensures proper lubrication and consistent hydraulic pressure under all driving conditions. Regular fluid and filter changes are crucial to prevent clutch wear and slipping — especially for trucks that see frequent towing or stop-and-go traffic.

Upgrading to a deep transmission pan adds fluid capacity and improves cooling efficiency, while built-in drain plugs and temperature ports make servicing simpler. Combined with proper fluid maintenance, these upgrades help stabilize transmission temperatures and reduce internal wear, ensuring dependable shifts and performance.

Whether you’re keeping things stock or preparing for heavy towing, maintaining your automatic transmission with quality parts and fluids is one of the smartest investments you can make for your F-150 Power Stroke.
