Overdrive Gearboxes and Equipment Splitters Behind the AX15 Transmission
(any overdrive gearboxes and gear splitters that work behind an ax15?)
The AX15 handbook transmission, a robust five-speed transmission created by Aisin-Warner, is commonly identified for its sturdiness and versatility in applications such as Jeep Wranglers, Cherokees, and Dodge Dakotas. While the AX15 uses a balanced gear spread for basic use, incorporating auxiliary overdrive transmissions or gear splitters can improve its performance for specialized scenarios, consisting of freeway travelling, hauling, or off-road driving. This article examines the concepts, advantages, and integration challenges of these aftermarket systems.
** Overdrive Gearboxes **.
An overdrive transmission is a complementary system installed behind the major transmission to offer an extra gear proportion, generally in between 0.70:1 and 0.80:1. This reduces engine RPM during high-speed cruising, enhancing gas performance and decreasing wear. For the AX15, which already consists of a 0.79:1 overdrive in 5th gear, including a secondary overdrive device like the Equipment Vendors Under/Overdrive can create an ultra-low last drive proportion (e.g., 0.79 x 0.78 = ~ 0.62:1). This properly decreases engine rate by approximately 22%, suitable for long-distance traveling or towing where thermal and mechanical anxiety on the engine have to be lessened.
Installation includes connecting the overdrive system to the AX15’s result shaft, adhered to by the transfer situation or driveshaft. Engagement is normally electronic, through a dash-mounted button or a button on the equipment lever. The Equipment Vendors system, as an example, makes use of a worldly gearset and works with the AX15’s 23-spline result shaft. Nonetheless, driveline modifications– such as shortening the rear driveshaft and transferring crossmembers– may be essential to fit the included length.
** Equipment Splitters **.
Gear splitters, or variety shifters, separate each existing gear right into two proportions, properly doubling the variety of readily available gears. Unlike overdrives, splitters operate throughout the whole transmission, enabling better control over engine load and RPM. For the AX15, a splitter like the United States Gear Splitter can be placed in between the transmission and transfer instance, using a “high-low” array for every gear. This transforms the five-speed right into a ten-speed transmission, advantageous for heavy transporting or off-road precision where maintaining optimal torque is crucial.
Splitters utilize an additional gearset (commonly worldly or countershaft-based) activated using a committed air or electrical actuator. Chauffeurs toggle between split modes making use of a separate shifter or a twin-stick arrangement. As an example, in “low” setting, initial equipment might operate at a 4.01:1 ratio, while “high” setting shifts it to 3.03:1, permitting the engine to remain within its power band regardless of varying tons.
** Assimilation with the AX15 **.
Both systems need cautious assimilation with the AX15’s architecture. Overdrives are easier to set up, as they operate as standalone units, yet may reduce ground clearance due to their positioning. Splitters demand a lot more considerable modifications, consisting of reinforced mounts and customized shift links. Compatibility with four-wheel-drive systems is one more factor to consider; the included size of complementary units might require a shorter back driveshaft or moving of the transfer situation.
Electric and hydraulic user interfaces should additionally be dealt with. Overdrives often need a standalone control module to take care of involvement timing, while splitters might require pneumatic lines or extra wiring. Proper lubrication and cooling are essential, as complementary units introduce additional warmth and friction.
** Advantages and Drawbacks **.
The main advantage of overdrives is improved fuel economic climate and reduced NVH (sound, vibration, cruelty) at freeway speeds. Gear splitters master lots adaptability, enabling chauffeurs to maximize equipment option for high qualities or unsteady terrain. Nonetheless, both systems add complexity, weight (30– 50 lbs), and expense ($ 2,500–$ 4,000 for an Equipment Vendors system). Driveline harmonics can also end up being an issue if parts are not well balanced post-installation.
** Verdict **.

Overdrive gearboxes and equipment splitters substantially increase the AX15’s capacities, making it versatile to diverse operational needs. While overdrives are optimal for highway-centric applications, splitters offer unparalleled control popular settings. Mechanical designers evaluating these systems must evaluate the benefits versus installment complexity and expense, guaranteeing placement with the lorry’s intended usage. With correct assimilation, these auxiliary systems can change the AX15 right into a complex transmission service, linking the space between performance and efficiency.
