UNSPSC 25173823: Gearbox or transmission repair kit

A gearbox or transmission repair/rebuild kit contains all the parts that, by design are going to eventually wear out, and consist mainly of new clutches, bands, seals, gaskets, bushings, bearings, internal sealing rings along with a new transmission filter.

UNSPSC 25173823 Gearbox or transmission repair kit is a Commodity code that covers specialized rebuild components, gaskets, seals, bearings, and hardware kits for restoring transmissions and gearboxes in transit buses, school buses, municipal fleet vehicles, and heavy equipment. State and local governments source these kits as line items within broader transmission and drivetrain repair contracts, particularly when in-house or contracted repair shops perform rebuild work rather than full transmission replacement. The issuing bodies span county transportation departments, municipal transit authorities, school districts, and consolidated city-county governments managing large vehicle fleets; repeat activity centers on transit systems and school districts operating hundreds of buses requiring preventive transmission maintenance and periodic rebuild cycles.

Recent solicitations under transmission and drivetrain service codes show steady demand across the Southeast and upper Midwest. Columbus Consolidated Government (City of Columbus) issued RFB No. 26_0031 in February 2026 seeking B400R transmission repair and rebuild services for METRA Transit System on an as-needed annual contract basis, with bids due March 4, 2026. Broward County Transportation Department posted an open-end contract (TRN2132053B1) due June 1, 2026 for Cummins engine and chassis system repairs across its BCT Bus Fleet, encompassing drivetrain components including transmissions and drive axles. Seminole County Public Schools in Florida issued ITB #25260067B-TL due January 8, 2026 for supplemental school bus and white fleet parts and repairs covering approximately 409 buses and 135 white vehicles. Parkway School District in Missouri sought bus fleet OEM parts and repair services through blanket purchase orders with an RFB response date of May 19, 2026. The source materials show no recent solicitations specifically tagged to UNSPSC 25173823 by code number; transmission service contracts and bus fleet repair opportunities are the primary activity vectors where gearbox and transmission repair kits are typically purchased as component line items rather than standalone procurements.
