Engine and Transmission Overview
The 2002 Mustang GT was powered by a 4.6-liter‚ single overhead cam‚ V8 engine‚ producing 260 horsepower and 302 lb-ft of torque. This engine‚ coupled with the available manual transmissions‚ provided a thrilling driving experience. The T5‚ a five-speed manual transmission‚ was a carryover from previous Mustang generations‚ offering a proven and reliable option. However‚ Ford introduced the TR3650 five-speed manual transmission in 2001‚ aiming to improve fuel economy and performance. The TR3650 featured a revised gear ratio for the fifth gear‚ resulting in lower engine RPMs at highway speeds‚ contributing to better fuel efficiency. Despite being a newer transmission‚ the TR3650 faced criticism for its durability‚ prompting some enthusiasts to opt for the T5. Ultimately‚ the choice between the T5 and TR3650 depended on individual priorities‚ with the T5 providing a familiar and reliable experience‚ while the TR3650 offered a more fuel-efficient option‚ albeit with potential durability concerns.
The Tremec TR3650 Transmission
The TR3650‚ a five-speed manual transmission‚ was a significant departure from the T5‚ offering a revised gear ratio for the fifth gear‚ resulting in lower engine RPMs at highway speeds. While this gear ratio change aimed to improve fuel economy‚ it also introduced a potential weakness in the transmission’s design. This weakness manifested in the form of a tendency for the fifth gear to fail prematurely‚ particularly under heavy loads or high-performance modifications. Despite its shortcomings‚ the TR3650 offered a smoother and more refined shifting experience compared to the T5‚ and its increased fuel efficiency was a welcome benefit for many drivers. However‚ the potential for fifth-gear failure and the availability of the more robust T5 led some enthusiasts to choose the older transmission for its proven reliability.
Key Features of the TR3650
The TR3650 transmission‚ while sharing some similarities with the T5‚ offered a distinct set of features. It boasted a revised gear ratio for the fifth gear‚ allowing for lower engine RPMs at highway speeds‚ a welcome change for fuel economy. The TR3650 also incorporated a hydraulic clutch system‚ which provided a smoother and more consistent engagement compared to the cable-operated clutch found in the T5. This hydraulic system contributed to a more refined driving experience‚ particularly during low-speed maneuvers and stop-and-go traffic. Furthermore‚ the TR3650 featured a larger input shaft‚ designed to handle the increased torque produced by the 4.6L V8 engine‚ making it a more robust option for handling the power of the Mustang GT.
Advantages and Disadvantages
The TR3650 offered several advantages over its predecessor. The revised fifth gear ratio contributed to improved fuel economy‚ a welcome feature for everyday driving. The hydraulic clutch system provided a smoother and more refined driving experience‚ particularly during low-speed maneuvers and stop-and-go traffic. The larger input shaft also enhanced the transmission’s durability‚ making it more capable of handling the power output of the 4.6L V8 engine. However‚ the TR3650 also had its drawbacks. It was known for its susceptibility to premature wear‚ particularly in the synchronizers and the fifth gear. This vulnerability was often attributed to the transmission’s relatively lightweight design‚ which could lead to issues when subjected to aggressive driving or heavy towing.
T5 Transmission⁚ A Legacy Option
The T5 transmission‚ a stalwart in Ford’s performance lineup‚ enjoyed a long and storied history‚ serving as the standard manual transmission for Mustangs from 1983 onwards. Its reputation for durability and reliability made it a favorite among enthusiasts. The T5 was renowned for its robust construction‚ featuring a cast-iron case and a durable gearset‚ which could withstand the rigors of high-performance driving. It also offered a smooth and precise shifting experience‚ contributing to the Mustang’s engaging driving dynamics. However‚ the T5 was not without its limitations. The availability of replacement parts was becoming increasingly challenging‚ as the transmission was discontinued in 2004. Additionally‚ the T5’s gear ratios were not as well-suited for highway cruising as the TR3650‚ making it less efficient for longer journeys.
History and Popularity
The T5 transmission‚ introduced in 1983‚ quickly became a staple in Ford’s performance vehicles‚ including the Mustang. Its robust design and smooth shifting action earned it a reputation for reliability and durability. The T5’s popularity stemmed from its ability to handle the power output of the 5.0L V8 engine‚ making it a popular choice for performance enthusiasts who sought a manual transmission option. The T5’s popularity extended beyond the Mustang‚ as it was also used in other Ford models‚ including the F-Series trucks‚ and the Thunderbird. The T5’s reputation for durability and reliability ensured its widespread adoption‚ establishing it as a cornerstone of Ford’s performance transmission lineup.
Comparison to the TR3650
While the T5 was a proven performer‚ the TR3650 brought a number of improvements to the table. The TR3650 featured a revised gear ratio‚ with a taller fifth gear designed to enhance fuel economy‚ a key concern for the era. The TR3650 also benefitted from a more robust internal design‚ with stronger gears and shafts‚ designed to handle increased torque output. However‚ some enthusiasts found the TR3650’s shifting feel to be less crisp than the T5‚ and the transmission was prone to occasional issues with its synchros‚ especially in higher gears. Ultimately‚ the choice between the two transmissions depended on individual preferences and priorities‚ with the T5 offering proven reliability and a more direct shifting feel‚ while the TR3650 prioritized fuel efficiency and enhanced durability.
