Mechanics advise drivers to check their transmission fluid once a week and to have the fluid changed every 30,000 miles. Maintaining an adequate fluid level will give your truck its best performance. The fluid lubricates the transmission, allowing your Nissan Titan to change gears freely and helping extend the life of your transmission. Checking the transmission fluid and putting more in is fairly easy to do, and no tools are required.
Park the truck on level ground and apply the emergency brake.
Start your Nissan Titan and allow it to run for a few minutes.
Lift the hood and prop it open. Pull the transmission dipstick from its well and wipe it clean with a rag.
Put the dipstick back into the well all the way and let it sit for a few seconds.
Pull out the dipstick and take note of the "FILL" line. If the fluid falls below this line, you must add more.
Place a funnel in the transmission fluid well. Slowly add more fluid a little at a time.
Check the fluid level again and add more as needed. Continue until the fluid is at the proper level.
Put the dipstick back in the well. Close the hood and shut off the engine.
