Product Details

This National thrust needle bearing is engineered for manual transmission use where precise bearing dimensions are critical. It serves applications across Ford Mustang models with Tremec 3550 transmission, Ford F-Series and Bronco manual transmission setups, and a wide range of Dodge, Chevrolet, and GMC trucks and vans listed in the fitment data. This part cross-references 235382 and FA35688 for the same application.

National FA-35688 is a practical replacement choice when servicing transmission gear assemblies that require a thrust needle bearing with the listed bore and outside diameter. The OE-spec focus helps maintain proper fit in supported manual transmission positions, including 3rd and 4th gear applications shown in the vehicle data.

What It Helps Address

• Excessive play in a manual transmission gear assembly
• Noise caused by worn thrust bearing surfaces
• Rough or inconsistent gear support in 3rd or 4th position applications
• Transmission rebuild needs on older Ford, Dodge, Chevrolet, and GMC platforms
• Replacement of a worn thrust needle bearing during service work

Installation Notes and Tips

Verify the bore, outside diameter, and width against the original bearing before installation. Confirm transmission type and position carefully, since fitment varies by model, year, and gearbox family such as New Process 435A, 435L, 435FE, 435FL, 435GA, 435GL, 445, and Tremec 3550 applications. Clean the bearing seat and inspect related transmission components for wear before assembly.

Quality Assurance

National manufactures this needle bearing with premium materials and OE-spec engineering standards for consistent transmission service performance.
