NV T350 (A578) Manual Transaxle

The NV T350 (A-578) transaxle is a fully synchronized (except reverse), constant-mesh transaxle. The transaxle case is constructed of die-cast aluminum, and is a two-piece design (bell housing case half and rear housing case half) with a steel end plate bearing cover. All forward gears are in constant-mesh with each other, which eliminates the need to move gears together for engagement. This feature improves response and eliminates gear "clash" noises. The reverse idler gear is supported and rotates on a spindle idler shaft. Depending on application, a reverse gear brake/blocking ring is available on some units for shifting ease.

The NV T350 (A-578) transaxle also incorporates an open differential, which converts power from the output shaft pinion gear to the differential ring gear. The differential case transfers torque from the ring gear to the drive axles by means of differential side gears.

The NV T350 (A-578) transaxle internal components can only be serviced by separating the case halves.

CAUTION: The transaxle output shaft is serviced as a unit. No disassembly and reassembly is possible. Damage to the transaxle may result.
