Spicer TTC 310227X is a synchronizer assembly. Our parts manual lists it as the 2nd and 3rd synchronizer in the mainshaft output group of the CM6052-A, CM6052-B, CM6052-C, CM6052-D, CM6252-B, CM6253-A, CM6253-B and ES70-5A transmissions, one per assembly, next to the 2nd and 3rd clutch gear and snap ring. A synchronizer matches the speed of a gear to the shift sleeve so the two engage smoothly instead of the teeth clashing. When one wears, shifts grind or crunch, the lever resists the gear, or the transmission pops out of gear. A genuine Spicer TTC part from Pro Gear and Transmission.
