What to know before you buy
Compatibility
Heavy-duty fitment turns on more than year/make/model. Engine family, ECM calibration, emissions configuration (pre-EGR, EGR, DPF/SCR), and drivetrain ratios all matter. Our AI cross-checks the details you provide, and a specialist verifies fitment against the actual unit before anything ships.
Used vs. Rebuilt / Reman
Used (running take-out) units are the fastest and lowest-cost path when a low-hour core is available. Rebuilt/reman units cost more but ship with fresh internals and a longer warranty. For over-the-road trucks that need to stay earning, we'll lay out both so you can weigh downtime against total cost.
Warranty
Warranty terms vary by supplier and unit condition — used, rebuilt, and reman each carry different coverage. Options and exact terms are confirmed in your written quote before purchase; nothing is assumed.
Freight & Delivery
Heavy assemblies ship LTL freight on a pallet, typically 2–7 business days depending on lane and residential vs. commercial delivery. Liftgate and terminal pickup options are quoted per destination.
Frequently asked questions
What do I need to match a heavy-duty transmission?
Ratio, torque rating, speed count and input configuration. For AMTs, software/rating compatibility matters too. Share the tag or VIN and we'll confirm.
Can I swap a manual for an AMT?
Sometimes — but it involves clutch, controls and calibration changes. A specialist will tell you whether it's practical for your truck.
