How to Check Transmission Fluid Levels
Checking the transmission fluid levels in your 2018 Nissan Altima is a straightforward process that you can do at home. Here’s a step-by-step guide to help you ensure your vehicle’s transmission is well-maintained.
Step 1: Gather Your Tools
You will need a dipstick, funnel, and the recommended NS-3 CVT fluid.
Step 2: Prepare Your Vehicle
Park your Altima on a level surface and engage the parking brake. Start the engine and let it warm up for a few minutes, allowing the transmission fluid to circulate.
Step 3: Locate the Dipstick
Open the hood and locate the transmission dipstick. It’s typically found near the back of the engine.
Step 4: Check Fluid Levels
Pull out the dipstick and wipe it clean with a cloth. Reinsert it fully and then remove it again to check the fluid level. The fluid should reach the recommended mark on the dipstick.
Step 5: Add Fluid if Necessary
If the fluid is below the recommended level, use a funnel to add the NS-3 fluid carefully. Avoid overfilling, as that can cause issues.
Step 6: Recheck
After adding fluid, recheck the level to ensure it’s within the appropriate range.
Regularly checking your transmission fluid can prevent issues and extend the life of your Altima.
Changing Transmission Fluid
Changing the transmission fluid in your 2018 Nissan Altima is an essential maintenance task. Here’s how to do it correctly.
Step 1: Gather Supplies
You will need NS-3 CVT fluid, a new transmission filter, a wrench, a drain pan, and a funnel.
Step 2: Prepare the Vehicle
Jack up your Altima and secure it with jack stands. Ensure the engine is off and cool.
Step 3: Drain Old Fluid
Locate the transmission pan and use a wrench to remove the drain plug. Allow the old fluid to completely drain into the pan.
Step 4: Replace the Filter
Remove the old transmission filter and replace it with a new one. This step is crucial for maintaining fluid cleanliness.
Step 5: Add New Fluid
Using a funnel, pour the new NS-3 CVT fluid into the transmission through the dipstick tube. Refer to your owner’s manual for the exact amount needed.
Step 6: Check Levels
After adding fluid, start the engine and let it run for a few minutes. Check the fluid level again and add more if necessary.
Step 7: Dispose of Old Fluid
Properly dispose of the old transmission fluid at a designated recycling center.
Changing your transmission fluid every 30,000 to 60,000 miles can greatly enhance your Altima’s performance.
