Why You Should Change Your Transmission Fluid
Transmission fluid is essential for keeping your car's transmission running smoothly. Over time, it degrades, leading to poor shifting and potential damage. Changing it yourself can save hundreds compared to a mechanic.
Tools and Materials You'll Need
Before starting, gather these items:
- New transmission fluid (check your owner's manual for the correct type)
- Drain pan
- Socket set and wrenches
- Jack and jack stands
- Funnel
- Gloves and safety glasses
Step-by-Step Transmission Fluid Change Guide
1. Prepare Your Vehicle
Park on a flat surface and engage the parking brake. Lift the car safely using a jack and secure it with jack stands. Always ensure it's stable before working underneath.
2. Locate the Transmission Pan
Find the transmission pan under your vehicle. Some vehicles have a drain plug, while others require removing the entire pan.
3. Drain the Old Fluid
Place the drain pan beneath the transmission pan. Remove the plug or bolts carefully—fluid will come out quickly. Wear gloves to avoid skin contact.
4. Replace the Filter (if applicable)
Some vehicles have a transmission filter inside the pan. If yours does, replace it while the pan is off for optimal performance.
5. Reinstall the Pan and Refill New Fluid
Reattach the pan with a new gasket if needed. Use a funnel to pour fresh transmission fluid into the dipstick tube. Check levels according to your manual.
Common Mistakes to Avoid
- Overfilling: Too much fluid can cause overheating.
- Wrong fluid type: Always use the specification listed in your owner's manual.
- Skipping the filter: If your car has one, replace it to prevent contaminants from recirculating.
When to Change Transmission Fluid
Most manufacturers recommend changing it every 30,000-60,000 miles, but check your manual for specifics. If your transmission is slipping or shifting roughly, it may be overdue.
