NIGP 55778: Transmission Parts

NIGP 55778 Transmission Parts, an Item code, covers replacement transmission components and transmission service work that state and local governments procure for vehicle and transit fleet maintenance. Recent solicitations show school districts, transit authorities, and municipal utilities purchasing transmission dipsticks, solenoid assemblies, oil coolers, compression springs, and complete transmission rebuild services on an as-needed basis under blanket purchase orders and annual service contracts. Parkway School District in Missouri (RFB posted May 5, 2026, due May 19, 2026) sought OEM replacement transmission parts and repair labor for its bus fleet, requiring vendors to stock commonly needed items and source unavailable parts within three days. Rockwood School District in Missouri (RFB posted March 12, 2026, due April 9, 2026) solicited pricing for bus and fleet vehicle parts across a diverse inventory including Bluebird, Ford, Chevrolet, and other manufacturers for the 2026–2027 fiscal year. Dallas Area Rapid Transit Authority (DART) has posted multiple narrow-scope procurements for specific transmission components, including a transmission dipstick (ITB posted March 16, 2026, due March 19, 2026), a solenoid assembly for 11-CG transmissions (RFQ posted February 22, 2026, due February 25, 2026), and a transmission oil cooler (RFQ posted February 11, 2026, due February 14, 2026). The issuing bodies span school districts, transit authorities, and municipal utilities, with school districts and transit systems as the most active buyer segments under this code.

Activity concentrates in the Midwest and South, with Missouri school districts and the Dallas Area Rapid Transit Authority representing the largest recent volume. The City of Ocala, Florida (ITB posted April 13, 2026, due January 16, 2026) solicited six 250 KVA distribution voltage regulators, representing utility infrastructure procurement outside the traditional vehicle transmission scope. Columbus Consolidated Government (RFB posted February 16, 2026, due March 4, 2026) sought B400R transmission repair and rebuild services for its METRA Transit System on an annual as-needed contract. Response windows are typically three to four days for DART procurements and two to three weeks for school district RFBs. Vendor requirements commonly include proof of insurance, equipment stock maintenance, timely delivery capability, and FOB Destination pricing with freight included. No set-aside designations for disadvantaged enterprises appear in the recent solicitations, though Missouri school districts encourage U.S. manufacturing and may apply state or local vendor preferences where quality and pricing are comparable.
