- Inspect Fluid: As the old oil drains, observe its color and consistency. Dark, sludgy fluid with metallic particles indicates significant wear. A small amount of fine metal particulate on the magnetic drain plug (if equipped) is normal, but large chunks are a concern.
- Allow to Drain Completely: Let the fluid drain for at least 15-20 minutes, or until it’s just a slow drip.
- Clean and Reinstall Drain Plug: Clean the drain plug and its sealing washer (replace the washer if it’s a crush washer or looks damaged). Reinstall the drain plug and tighten it to the manufacturer’s specified torque. Do not overtighten, as this can strip the threads.
Refilling with Fresh Gearbox Oil
Now for the good stuff – getting that clean, fresh fluid in!
- Prepare Fluid Pump: Attach your fluid pump to the new gearbox oil bottle.
- Insert Fill Hose: Insert the pump’s hose into the transmission’s fill plug opening.
- Pump New Fluid: Begin pumping the fresh manual transmission fluid into the gearbox. Continue pumping until the fluid starts to weep or trickle out of the fill hole. This indicates the transmission is full to the correct level.
- Remove Pump and Reinstall Fill Plug: Once full, quickly remove the pump hose and reinstall the fill plug. Clean the fill plug and its washer, replacing the washer if necessary. Tighten the fill plug to the manufacturer’s specified torque.
Post-Change Checks & Tips
You’re almost done! A few final steps to ensure everything is perfect.
- Lower Vehicle: Carefully raise the vehicle off the jack stands, then lower it completely to the ground.
- Check for Leaks: Start the engine, let it run for a few minutes, and then turn it off. Inspect the drain and fill plugs for any signs of leaks.
- Test Drive: Take your Mazda CX-5 for a short test drive. Pay attention to how the gears feel. You should notice smoother, more positive shifts.
- Re-Check Fluid Level (Optional but Recommended): After your test drive, if you’re concerned about the level, you can re-lift the car safely and briefly remove the fill plug to confirm fluid is still at the weep point.
