Complete transmission countershaft assembly removed from a 1978 Honda ATC90. This is not just the bare shaft — it includes all gears installed on the countershaft, exactly as shown in the photos. Honda part number 23220-053-030, 23T.
Assembly is in good used condition with no visible damage. Gears and shaft move freely with no binding or issues noted. Teeth are clean and intact with no chips or cracks. A solid, ready-to-use original transmission assembly.
These complete countershaft assemblies are getting harder to find for older ATC90 machines.
What you see in the photos is exactly what you will receive.
Be sure to inspect all photos closely to confirm what is included, as well as the condition and proper fitment of the part before purchasing.
⚠️ Hardware Disclaimer: Any hardware (bolts, clips, fasteners, etc.) — if any — shown in photos is not guaranteed to be included and should be considered a free extra if received. Listings are for the main part only unless specifically stated otherwise.
