FY2025 federal contract obligations, USAspending.gov
NAICS 336350 obligated $371 million in FY2025 across 3,117 contract actions. DoD is $361 million, or 97 percent, and GSA is $10 million. The average action is around $119,000, which reflects driveline component and assembly demand behind tactical and non-tactical vehicle fleets that are kept in service far longer than commercial fleets are.
What belongs here
Manufacturing and rebuilding motor vehicle transmissions and power train parts. The definition includes rebuilding, which is unusual and consequential: a remanufacturer of transmissions and driveline assemblies is a manufacturer under this code, not a repair service.
- Non-vehicle mechanical power transmission components are 333613.
- Repairing vehicles rather than rebuilding components is 811111.
- Complete vehicle manufacturing is 336110.
Competing in this code
237 IDVs against 3,117 actions points to long-term supply arrangements carrying most of the volume. The remanufacturing inclusion is the strategic opening. Military vehicle fleets stay in service for decades, and the original transmission supply chain does not stay with them, so qualified rebuild sources for legacy drivelines face persistent demand and thin competition. Building the qualification package for one driveline family, including test protocols and warranty terms the government will accept, converts into repeat awards that new entrants cannot easily contest.
Frequently Asked
NAICS 336350 questions, answered.
What is the SBA size standard for NAICS 336350?
SBA sets it at 1,500 employees, counted as a 24-month average headcount across your company and every affiliate, not revenue. At or under that number you are small on NAICS 336350 solicitations and eligible for the set-asides in this code.
Which agencies buy transmission and power train parts under NAICS 336350?
FY2025 obligations: DoD ($361 million), GSA ($10 million). At 97 percent DoD, this is driveline demand behind tactical and non-tactical fleets that stay in service far longer than commercial vehicles do.
Is transmission rebuilding classified as manufacturing in NAICS 336350?
Yes. The industry definition explicitly covers manufacturing and rebuilding motor vehicle transmissions and power train parts. A remanufacturer is a manufacturer under this code, which matters for set-aside eligibility, the nonmanufacturer rule, and how your capability is evaluated against original equipment suppliers.
What kind of supplier wins repeat work in NAICS 336350?
Qualified rebuild sources for legacy drivelines. Military vehicle fleets outlast their original transmission supply chains, and the government needs a source it has already accepted. Building the qualification package once, including test protocols and acceptable warranty terms, produces repeat awards that new entrants cannot easily contest.
