What transmission is in a 1965 Mustang 289?

The 1965 Ford Mustang 289 was equipped with a three-speed manual transmission as the standard offering. This transmission was a key component of the iconic pony car's driving experience, providing the driver with direct control over the engine's power delivery.


The Three-Speed Manual Transmission


The three-speed manual transmission in the 1965 Mustang 289 was a robust and reliable unit, designed to handle the power output of the 289 cubic inch V8 engine. This transmission featured a synchronized design, allowing for smooth and precise gear changes, even at higher engine speeds.


The gear ratios of the three-speed manual transmission were optimized to provide a balance between acceleration and top-end speed. The first gear ratio was designed for rapid takeoff from a standstill, the second gear offered a good compromise between acceleration and fuel efficiency, and the third gear allowed the Mustang to reach its top speed while maintaining a comfortable engine rpm.


Driving Characteristics


The three-speed manual transmission in the 1965 Mustang 289 provided the driver with a direct and engaging driving experience. The short-throw shifter allowed for quick and precise gear changes, enabling the driver to extract the maximum performance from the 289 V8 engine.


The clutch pedal required a moderate amount of effort, providing the driver with a good feel for the engagement and disengagement of the clutch. This allowed for smooth and controlled launches, as well as confident gear changes during spirited driving.


Availability and Options


The three-speed manual transmission was the standard offering for the 1965 Mustang 289. However, Ford also offered an optional four-speed manual transmission for drivers who desired even more control and performance from their Mustang.


The four-speed manual transmission featured a close-ratio design, which provided tighter gear spacing for improved acceleration and responsiveness. This transmission was a popular choice among enthusiasts who wanted to extract the maximum performance from their Mustang 289.


Regardless of the transmission choice, the 1965 Ford Mustang 289 was a true driver's car, offering an engaging and exhilarating driving experience that has cemented its place in automotive history.

Does the VIN tell what transmission I have?


The VIN does not directly include a digit solely dedicated to identifying the transmission. However, the 8th digit often represents the engine type, which can help determine the transmission when combined with manufacturer-specific information.



What is the best transmission for a 65 Mustang?


For a 1965 – 1966 Mustang we recommend a T5 transmission for engines making under 450hp. The TTKX requires the cross-member to be moved rearward 2-3/4″ on 65-66 model, for 67-73 models this is not necessary. TKX transmissions are recommended when you're making 450 hp +.



What is the difference between T5 and TR3650?


The easiest way to tell the difference is to look for the drain plug. The T-5 (T-45) transmission has the drain plug on the passenger side of the transmission case. The TR3650 transmission has the drain plug on the bottom of the transmission case, pointing straight down towards the ground.
