Tools and Materials You’ll Need
- New CVT fluid (check your owner’s manual for recommended type and quantity)
- CVT fluid filter (if applicable)
- Funnel
- 10mm socket wrench

Step-by-Step Instructions
1. Safety First
Park your Nissan Altima on a level surface and engage the parking brake. Allow the engine to cool down completely.
2. Locate the Drain Plug
Slide under the vehicle and locate the CVT fluid drain plug. It’s typically a 10mm bolt located at the bottom of the transmission pan.
3. Drain the Old Fluid
Place the drain pan under the drain plug. Using a 10mm socket wrench, carefully loosen the drain plug. Allow the old CVT fluid to drain completely into the pan.
4. Remove the Fluid Filter (if applicable)
Some Nissan Altima models have a CVT fluid filter. If yours does, locate the filter housing, which is usually attached to the transmission pan. Remove the bolts holding the housing and pull out the old filter.
5. Clean the Drain Plug and Filter
Clean the drain plug and the fluid filter (if removed) with a clean rag. Remove any debris or old fluid residue.
6. Install the New Filter (if applicable)
If your Altima has a CVT fluid filter, insert the new filter into the housing and secure it with the bolts. Tighten the bolts snugly.
7. Replace the Drain Plug
Tighten the drain plug back into the transmission pan using the 10mm socket wrench. Make sure it’s snug but avoid overtightening.
8. Add New CVT Fluid
Using a funnel, pour the recommended amount of new CVT fluid into the transmission dipstick tube. Check the fluid level regularly using the dipstick and add more fluid as needed.
9. Check for Leaks
Start your Altima and let it run for a few minutes. Check under the vehicle for any leaks from the drain plug or the fluid filter housing. If you notice any leaks, tighten the components accordingly.
10. Reset the CVT Fluid Life Monitor
Your Nissan Altima may have a CVT fluid life monitor. After changing the fluid, you need to reset the monitor using a diagnostic scanner or by following the instructions in your owner’s manual.
Tips for Changing CVT Fluid
- Refer to your owner’s manual for the recommended CVT fluid type and change interval.
- Use only high-quality CVT fluid specifically designed for your Nissan Altima.
- If you’re not comfortable performing this task yourself, take your vehicle to a qualified mechanic.
- Changing the CVT fluid is an essential part of maintaining your Nissan Altima. Regular fluid changes will help extend the life of your transmission and keep your vehicle running smoothly.
