FAQ

What work fits NAICS 336350?
  • Manufacture and delivery of complete transmission assemblies built to OEM drawings with serial-level traceability and acceptance test reports.
  • Production of gear sets and differentials with material traceability, hardness and heat-treatment certificates, and functional test data.
  • Supply of drive shafts and torque converters with specified material grades, dimensional inspection reports, and balancing certifications for vehicle fleets.
  • Short-run prototype builds and engineering change implementation for power train components with accompanying test protocols and engineering change documentation.
When is NAICS 336350 a weak fit?
  • Complete engine manufacturing where the primary deliverable is internal combustion engines and engine blocks rather than transmission or driveline components.
  • Vehicle electronic control systems and software development where the focus is ECU firmware and vehicle controls rather than mechanical power train hardware manufacturing.
  • Vehicle assembly contracts that procure complete vehicle integration and system-level acceptance rather than discrete manufacturing of transmission or driveline parts.
What solicitation language points to NAICS 336350?
  • Line items reference specific part drawings, revision levels, dimensional tolerance requirements, and required vendor material certifications.
  • Contract requires submission of torque, endurance, and performance test reports plus evidence of heat-treatment process controls and inspection data.
  • Evaluation includes requirements for serial-number traceability, first article inspection, spare parts provisioning, and evidence of controlled production and acceptance testing.
