2018 Ram 2500 check transmission fluid

NOTE:To prevent dirt and water from entering the
transmission after checking or replenishing fluid, make
sure that the dipstick cap is properly reseated. It is normal
for the dipstick cap to spring back slightly from its fully
seated position, as long as its seal remains engaged in the
dipstick tube.
Fluid And Filter Changes — Eight-Speed
Transmission
Under normal operating conditions, the fluid installed at
the factory will provide satisfactory lubrication for the life
of the vehicle.
Routine fluid and filter changes are not required. However,
change the fluid and filter if the fluid becomes contami-
nated (with water, etc.), or if the transmission is disas-
sembled for any reason.
Fluid And Filter Changes — Six Speed Transmission
Refer to the “Maintenance Plan” for the proper mainte-
nance intervals.
In addition, change the fluid and filters if the fluid becomes
contaminated (with water, etc.), or if the transmission is
disassembled for any reason.
Rear Axle And 4x4 Front Driving Axle Fluid Level
For normal service, periodic fluid level checks are not
required. When the vehicle is serviced for other reasons the
exterior surfaces of the axle assembly should be inspected.
If gear oil leakage is suspected inspect the fluid level. Refer
to “Fluids And Lubricants” in “Technical Specifications”
for further information. This inspection should be made
with the vehicle in a level position.
For 1500 Model axles, the fluid level should be even with
the bottom of the fill hole (within 1/4 in (6.4 mm) of edge
of hole) for the FDU215 HD front axle and C235FE rear
axle.
For all 2500/3500 Model axles, the fluid level should be 1/4
in ± 1/4 in (6.4 mm ± 6.4 mm) below the fill hole on the 9.25
in front and 3/4 in ± 1/4 in (19 mm ± 6.4 mm) on 10.5 in
rear axles. The 11.5 in rear axle level should be 1/4 in ± 1/4
in (6.4 mm ± 6.4 mm) below the fill hole.
Lubricant Selection
Refer to “Fluids And Lubricants” in “Technical Specifica-
tion” for further information.
