Frequently Asked Questions
Common signs of transmission issues include difficulty shifting gears, unusual noises when in neutral, slipping gears, a burning smell, leaking fluid, and the check engine light turning on. These symptoms suggest your transmission needs immediate attention to avoid more severe issues.
Most manufacturers recommend changing transmission fluid every 50,000 to 100,000 kilometres for manual transmissions and every 100,000 to 150,000 kilometres for automatic transmissions. However, consult your vehicle’s manual or ask our experts at Cox Auto for specific recommendations.
Yes, aggressive driving, like rapid acceleration and hard braking, can strain your transmission. Additionally, towing heavy loads frequently or not using the appropriate gear can lead to premature wear and tear.
A transmission flush involves using a machine to remove all the old fluid and replace it with new fluid. A change only replaces about 50-60% of the fluid with new fluid. A flush is more comprehensive but isn’t always necessary or recommended for every vehicle.
The cost-effectiveness depends on the extent of the damage and the vehicle’s value. Minor repairs might be cost-effective, but if the transmission needs a complete overhaul or replacement, the costs can be significant. It’s important to get a professional assessment to weigh your options.
Regularly check the transmission fluid level and quality, follow your vehicle’s maintenance schedule for fluid changes, use the correct type of transmission fluid, and avoid overloading your vehicle. Additionally, staying on top of your regular service schedule will help you catch and address any issues early.
