T350 Manual Transaxle: Description: Lubricant/Additives

NV T350 (A-578) transaxles use Mopar® ATF+4 (Automatic Transmission Fluid-Type 9602). Hypoid gear lube or engine oil should not be used in this transaxle.  Hard shifting effort, bearing, gear, and/or synchronizer failure may occur if incorrect fluid is used.

The addition of any fluids to the transaxle, other than the fluid listed above, is not recommended. An exception to this policy is the use of special dyes to aid in detecting fluid leaks. The use of transmission sealers should be avoided, since they may adversely affect seals.
