Why Buy a Used Honda Transmission from Auto Power Source
Honda's reputation for transmission longevity is well earned — the brand's 5-speed automatics and B-series manuals routinely cross 200,000 miles with nothing more than fluid changes, and Acura's 6-speed manuals are still the benchmark by which enthusiasts judge short-throw feel. But the lineup is also one of the most code-sensitive in the industry. The 5-speed automatics alone include BYBA, BAYA, MGHA, MDPA, MAYA and B7XA — and they are not interchangeable. The CVT family adds SLYA, MKYA, CK and CW variations, and the modern 6/7/9-speeds bring even more codes. Buy the wrong code and the transmission may bolt up but will not shift correctly with your TCM.
Our 654+ verified Honda & Acura transmissions have all been pulled from low-mileage donor vehicles, cataloged by transmission code stamped on the case, and held in our climate-controlled warehouse pending sale. Each unit goes through our six-step inspection — VIN-matching, Shift-Testing through all gears under load by ASE-certified technicians, noise & smoke verification on the test stand, full visual inspection of case, seals and external solenoids, multi-angle photography, and palletized shipping. CVTs additionally receive a fluid colour check and belt/pulley inspection; V6 automatics are checked for the documented torque-converter shudder issue.
You pay a fraction of dealer-new pricing for identical Honda engineering, ship free on a heavy-duty pallet anywhere in the continental U.S., and you have 30 days from delivery to return for any reason — no restocking fees. Up to a 3-year warranty covers you if anything goes wrong after install. 46,000+ units shipped, 0% fitment-related returns.

Honda Transmission Buying Guide
Five things to verify before buying a used Honda or Acura transmission:
-
Match by the transmission code stamped on the case, not just by year/model. Honda codes (BYBA, BVGA, MGPA, SLYA, etc.) appear on a metal tag pressed into the bell housing. The code confirms the exact ratio set, gear count, and TCM compatibility — two transmissions for the same year of Accord can be entirely different units depending on engine (4-cyl vs V6) and trim.
-
For CVT units, demand fluid condition and belt-wear documentation. Honda's CVT is sensitive to degraded ATF — our inspection includes a fluid colour check, belt and pulley inspection, and a Shift-Test under load before any CVT unit ships.
-
Confirm FWD vs. AWD. Honda CR-V, Pilot, and Acura MDX come in both FWD and AWD configurations, and the transfer case and rear output differ between them. Always specify drivetrain at order.
-
For 2003-2009 Odyssey, Pilot and Acura V6 automatics, ask about torque-converter shudder. Honda's earlier V6 automatics had documented torque-converter lock-up issues on high-mileage donors. We test for this specifically and flag any affected units before they ship.
-
Plan on Honda DW-1 (or HCF-2 for CVT) fluid at install. Honda automatics require Honda-spec ATF — running a generic universal will cause shift issues and void warranty. CVTs require HCF-2 specifically. A full fluid change is part of every Honda transmission install.
Our ASE-certified technicians verify every one of these points against your VIN before any transmission ships.
