§ About

What to Know About Used Aux. Trans. Case

An auxiliary transmission case houses the gearing of a secondary gearbox used in conjunction with the main transmission on heavy-duty trucks, vocational vehicles, and some off-road equipment. These multi-speed auxiliary boxes multiply the gear range available to the driver and are common on large commercial rigs that need very low crawl gears or very high overdrive ratios. The auxiliary case is a precision casting, and when it cracks or suffers impact damage, the entire gearbox becomes unusable even if the internal gears are fine. Symptoms of damage include external leaks, gear noise under load, or difficulty shifting through the auxiliary range. Fluid loss leads to rapid internal wear if not corrected quickly. Redline lists 32 used auxiliary transmission cases from 7 sellers. Our inventory spans 16 makes and platforms including Chevrolet, Honda, Toyota, Ford, Daewoo. A used replacement case from a matching unit is the most economical fix. Use the filters to match by vehicle type, make, and gearbox model. Confirm bolt patterns and PTO port locations with the seller before purchasing.
