GENERAL INFORMATION
NV T350 MANUAL TRANSAXLE
NOTE: Safety goggles should be worn at all times
when working on these transaxles.
This five speed is a constant-mesh manual tran-
saxle. All gear ranges, except reverse, are synchro-
nized. The reverse gear utilizes a brake and blocking
ring for shifting ease. The reverse idler gear is sup-
ported on a sliding spindle idler shaft. The transaxle
case is aluminum with a steel end–plate bearing
cover. It is housed in a die-cast aluminum case fea-
turing a two–piece, middle split design (Fig. 1).
The NV T350 (A-578) transaxle internal compo-
nents can be serviced only by separating the gear
case from the bellhousing case.
