Allison ReTran®

Factory Spec Allison Remanufactured Transmissions

Save money, but don’t short yourself on quality.

Allison Transmission manufactures their previously used transmissions from the ground up at the Allison Transmission remanufacturing facility. In their process of screening to determine the quality of their used transmission parts before possible reuse, they disassemble the transmissions part-by-part to clean, test and grade each component to verifiably determine if it is sound for reuse.

When a used part fails Allison’s meticulous quality screening process, they outfit the ReTran® with genuine, new and exclusive Allison parts. Allison Transmission guarantees that every part and every process associated with an Allison ReTran® is 100% authentic. Only Allison ReTran® remanufactured transmissions undergo their proprietary dynamometer testing to ensure they exactly meet the original factory specs.

The fact that the quality of each used component included in the reman transmission is tested to meet new transmission specs means you get a more reliable and dependable remanufactured transmission. It’s the Allison promise you get with your authentic Allison ReTran®.

Meritor Auxiliary Transmission

Meritor’s FAT-30 Auxiliary Transmission

Heavy duty and extreme duty commercial and industrial vehicles require an auxiliary transmission for on and off-highway applications. Whether logging, mining, heavy haul, oil field or military, Meritor’s FAT-30 auxiliary transmission handles 30,000 foot-pounds (40,675 Nm) of input torque, the highest torque rating in the industry at twice the capacity of comparable products.

The FAT-30 is equipped with durable cast-iron housing, with traditional transfer case mounting, and it includes planetary gearing for smooth, quiet operation in a compact footprint. It is designed with a stay-cool, advanced cooling system to prevent overheating. The extreme duty configuration keeps the box in the frame even in severe and intense conditions over extended periods of time.

Get the FAT-30 with its ratio spread that allows for a broad performance range; from high reduction, rough off-road use to on-highway, extreme, heavy hauls at highway speeds while maintaining fuel economy with reduced wear in overdrive.

The Meritor FAT-30 auxiliary transmission is ideal for use on trucks and machinery in construction, utility, defense and heavy haul.

Ratio Spread: Direct 1.00:1, Underdrive 2.50:1, Overdrive 0.86:1

Drivetrain Component Repair & Service

While your truck is in the shop, Cummins can also check and service or repair the other major components of your drivetrain including hubs, clutch, flywheel, driveline, u-joints (universal joints), differential, axles and wheel seals.

Drivetrain repair and service options available to customers range from minimal repair or upgrade to full system replacement including fluid levels check, replacement of worn drivetrain components, partial rebuilds, complete rebuild, complete transmission overhaul and complete clutch repair to complete differential repair. Sometimes it is possible to install new, factory drivetrain parts to replace only those which are worn or it may be possible to order a new, complete, factory manufactured drivetrain system.
