Rebuild And Repair Use

This bushing kit is intended for overhaul, restoration, and repair of compatible Turbo-Hydramatic 250 and 350 transmissions. Transmission bushings support rotating shafts and internal assemblies. Replace worn, scored, loose, or damaged bushings during rebuild work to help restore proper component support and alignment.

Excessive bushing wear may contribute to shaft movement, worn sealing surfaces, fluid leakage, and accelerated wear of related internal hard parts. A complete inspection is recommended before assembly, including shafts, drums, pump components, extension housing, and mating surfaces.

Fitment Verification

Fits compatible GM TH250/TH250C and TH350/TH350C automatic transmissions from 1969-1986. Confirm the transmission model, identification, original parts, and service information before purchase. Vehicle make, model, and year alone are not sufficient to verify fitment.

K35901 and 44030 are provided as reference numbers to help identify the correct application. They do not indicate that this item is a genuine GM service part.

Fluid Service Guidance

Use the transmission manufacturer’s specified ATF after completing service. If adding Lubegard ATF Protectant, verify compatibility with the fluid and application, then follow the product directions. Lubegard ATF Protectant does not replace worn or damaged mechanical components.
