  2. Locate the transmission fluid dipstick, usually near the back of the engine compartment.
  3. Remove the dipstick and wipe it clean with a lint-free cloth or paper towel.
  4. Reinsert the dipstick fully and then remove it again to check the fluid level. The dipstick will have markings indicating the appropriate range.
  5. If the fluid level is low, add the recommended transmission fluid gradually, checking the level periodically until it reaches the correct range.
  6. If a fluid change is required, consult your owner’s manual or seek professional assistance to ensure the proper procedure is followed.

Remember, safety should always be a top priority when working on your truck. If you are unsure or uncomfortable performing any maintenance tasks, it is best to consult a qualified technician.


Keeping your Freightliner M2’s transmission fluid at the correct capacity is crucial for maintaining the overall health and performance of your truck. Regularly checking and changing the fluid, following the recommended capacity, and using the appropriate type of fluid will help prevent costly breakdowns and keep your truck running smoothly for miles to come.
