Review BORGWARNER T5 5-speed World Class Transmission Ford fits MUSTANG THUNDERBIRD

The BorgWarner E9ZR-7003-AA is a high-performance 5-speed manual transmission specifically designed for Ford Mustang and Thunderbird applications using the T5 transmission platform. This transmission is engineered to deliver robust and reliable performance, making it an excellent choice for enthusiasts seeking a stronger and more durable option for their Ford vehicles.

The E9ZR-7003-AA transmission features a heavy-duty design with an increased clamping pressure on the synchronizer rings, resulting in improved synchro action and smoother gear changes. This transmission also benefits from a triple-cone synchronizer design on first and reverse gears, enhancing the synchronization and engagement of these critical gears.

One of the most notable upgrades of this transmission is the use of a billet steel input shaft, which provides greater strength and durability compared to the standard cast input shaft. This upgrade is particularly beneficial for high-performance applications, where the increased torque and power demands can put additional stress on the transmission components.

Another notable improvement is the use of a steel 4th gear, replacing the standard aluminum gear. This change offers improved strength and durability, allowing for the handling of increased power levels and torque without compromising the overall performance or reliability of the transmission.

The BorgWarner E9ZR-7003-AA transmission also includes a high-performance clutch kit, featuring a heavy-duty pressure plate and a high-friction clutch disc. This upgraded clutch kit provides improved clamping force and torque capacity, ensuring optimal power transfer and smoother engagement between the engine and transmission.

Additionally, this transmission includes an upgraded reverse idler gear, which features a larger diameter and stronger construction for better reversing performance and durability. The transmission case is also upgraded with a thicker wall for added strength and rigidity.

The BorgWarner E9ZR-7003-AA transmission is a direct replacement for the stock T5 transmission in Ford Mustang and Thunderbird applications. It is designed to be a bolt-in upgrade, ensuring a hassle-free installation process. This transmission is perfect for enthusiasts seeking improved performance, reliability, and durability for their Ford Mustang or Thunderbird, making it an essential upgrade for any high-performance application.
