heavy-duty truck maintenance and mechanical repair

This bundle provides the essential components and tools for heavy-duty truck maintenance and mechanical repair, specifically for swapping out an Eaton 15-speed transmission. It is designed for professional mechanics and experienced owner-operators who regularly perform complex powertrain service. These products collectively ensure the job can be completed safely, efficiently, and with the correct parts and fluids.

Curated by Workshop Notes · Updated June 2026

Built for fleet owner-operators and heavy-duty mechanics who need to perform in-house gearbox overhauls to save on shop labor. Not for light-duty diesel owners or those without a high-capacity lift—this shop focuses strictly on Class 8 truck drivetrain service.

Curator's pick: Eaton Fuller 15-Speed Transmission Rebuild Kit

This kit includes the high-capacity bearings that actually hold up under load, unlike some of the generic sets that skip the input shaft spacer. It saves you from having to source individual shims mid-job when you realize your tolerances are off.

⚠ Worth knowing: Attempting a 15-speed swap without a dedicated heavy-duty transmission jack is a safety violation that will likely end in a cracked case or a trip to the ER. These units weigh over 600 pounds dry, and standard floor jacks cannot stabilize the offset weight of the auxiliary section.
