Fluid Level Check
The fluid level can be checked by removing the filler
plug. If the level of the lubricant is more than 1/2 in
(12 mm) below the bottom of the filler hole while the
vehicle is on level ground, enough lubricant should be
added to bring the level to 1/4 in (6 mm) below the
bottom of the filler hole.
Automatic Transmission – If Equipped
Lubricant Selection
Refer to “Fluids, Lubricants, and Genuine Parts” in
“Maintaining Your Vehicle” for further information.
Fluid Level Check – Ram Truck Only
The fluid level should be checked when the engine is
fully warmed up and the fluid in the transmission is at
normal operating temperature. At normal operating tem-
perature, the fluid cannot be held comfortably between
the fingertips. Operation of the transmission with an
improper fluid level will greatly reduce the life of the
transmission and of the fluid. Check the fluid level
whenever the vehicle is serviced.
To properly check the automatic transmission fluid level,
the following procedure must be used:
1. Operate the engine at idle speed and normal operating
temperature.
