2023 RAM CHASSIS CAB transmission fluid

SERVICING AND MAINTENANCE373
minimum of two minutes for the oil to fully
drain into the transmission before rechecking
the fluid level.
NOTE:If it is necessary to check the transmission below
the operating temperature, the fluid level should
be between the two “COLD” (lower) holes on the
dipstick with the fluid at 60-70°F / 16-21°C. Only
use the COLD region of the dipstick as a rough
reference when setting the fluid level after a trans -
mission service or fluid change. Re-check the fluid
level, and adjust as required, once the trans -
mission reaches normal operating temperature.
8. Reinsert the dipstick. Check for leaks. Release the parking brake.
NOTE:If it is necessary to check the transmission below
the operating temperature, the fluid level should
be between the two COLD (lower) holes on the
dipstick with the fluid at 68-86°F / 20-30°C. Only
use the COLD region of the dipstick as a rough
reference when setting the fluid level after a trans -
mission service or fluid change. Re-check the fluid
level, and adjust as required, once the trans -
mission reaches normal operating temperature.
Fluid And Filter Changes — 8-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 contaminated (with water, etc.), or if the
transmission is disassembled for any reason.
Fluid And Filter Changes — 6-Speed
Transmission
For the proper maintenance intervals Úpage 344.
In addition, change the fluid and filters if the fluid
becomes contaminated (with water, etc.), or if the
transmission is disassembled for any reason.
Selection Of Lubricant
It is important to use the proper transmission fluid
to ensure optimum transmission performance and
life. Use only the manufacturer’s specified
transmission fluid Ú page 421. It is important to
maintain the transmission fluid at the correct level
using the recommended fluid. No chemical flushes
should be used in any transmission; only the
approved lubricant should be used.
CAUTION!
If the fluid temperature is below 50°F (10°C) it
may not register on the dipstick. Do not add fluid
until the temperature is elevated enough to
produce an accurate reading. Run the engine at
idle, in PARK, to warm the fluid.
CAUTION!
If the fluid temperature is below 50°F (10°C) it
may not register on the dipstick. Do not add fluid
until the temperature is elevated enough to
produce an accurate reading. Run the engine at
idle, in PARK, to warm the fluid.
CAUTION!
Using a transmission fluid other than the
manufacturer’s recommended fluid may cause
deterioration in transmission shift quality and/or
torque converter shudder, and (for 6-speed
transmissions) will require more frequent fluid
and filter changes Ú page 421.
