Checking And Changing A/T Fluid Service
WARNING: This page is about a different car, the 2018 Nissan NV3500 HD, 2018 Nissan NV2500 HD, and 2018 Nissan NV1500. However, it is still accessible from the selected car via links, so may be relevant.
Increase ATF temperature by 80°C (176°F) once, and then check ATF level in 65°C (149°F) when adjusting ATF level.
NOTE:
JA60 uses both systems of a water-cooling and of an air-cooling. Air-cooling system has a by-pass valve. When ATF temperature is not over 50°C (122°F) with water-cooling system OFF, it does not flow to air-cooling system. If ATF level is set without the flow of ATF, the level will be 10 mm lower than the standard. Therefore, piping should be filled with ATF when adjusting level.
