Differences Between the T5 and T45 transmissions

The best transmission for you will depend on your needs and your driving style

The T5 and T45 are both five-speed manual transmissions that were used in a variety of Ford vehicles, including the Mustang, the Thunderbird, and the F-150. However, there are some key differences between the two transmissions.

The T5

The T5 was introduced in 1983 and was the standard transmission for many Ford vehicles until it was replaced by the T45 in 1996. The T5 is a relatively lightweight transmission, and it is known for its smooth shifting and its ability to handle high horsepower. However, the T5 is not as strong as the T45, and it is not as well-suited for high-performance applications.

The T45

The T45 was introduced in 1996 and was designed to be a more durable and stronger transmission than the T5. The T45 is also slightly larger and heavier than the T5, but it is still considered to be a relatively lightweight transmission. The T45 is well-suited for high-performance applications, and it is often used in vehicles that are modified for racing.

Here is a table that summarizes the key difference between t5 and t45 transmissions:

Feature    T5    T45
Weight    Lighter    Heavier
Shifting    Smooth    Slightly notchy
Power handling    Good    Excellent
Durability    Less durable    More durable
Suitability for high-performance applications    Less suitable    More suitable
Which transmission is right for you?

The best transmission for you will depend on your needs and your driving style. If you are looking for a lightweight and smooth-shifting transmission, the T5 is a good option. If you are looking for a durable and strong transmission that is well-suited for high-performance applications, the T45 is a better choice.

Here are some additional factors to consider when choosing between a T5 and a T45 transmission:

The type of vehicle you drive. If you drive a light car, the T5 may be a good option. If you drive a heavier car or a car that is modified for racing, the T45 may be a better choice.
Your budget. The T5 is typically less expensive than the T45.
Your driving style. If you are a heavy shifter or if you tow a lot, the T45 may be a better choice.
