Is it necessary to change transmission fluid at a 4S shop?

It is not necessary to change the transmission fluid at a 4S shop; it can also be done at an external repair shop. Its functions are: 1. To keep the gear system clean; 2. To lubricate the transmission components. Signs that transmission fluid needs to be changed include: 1. Vehicle shaking and gear shifting hesitation; 2. The dashboard showing a transmission overheating warning; 3. The car stalling; 4. Unusual noises. The functions of the transmission are: 1. To change the transmission ratio; 2. To expand the torque and speed of the driving wheels; 3. To allow the car to reverse; 4. To facilitate gear shifting or power output. Transmission maintenance methods include: 1. Regularly checking the fluid level; 2. Avoiding skipping gears when upshifting; 3. Not forcing the transmission into neutral; 4. Not shortening the idle warm-up time; 5. Avoiding gear grinding when shifting.
My car has been running for over a decade, and the transmission fluid has been changed several times. At first, I also thought it wasn't necessary to go to a 4S shop, feeling it was a bit expensive. But now I really recommend prioritizing it, especially if your car is still under warranty. The 4S shop uses original factory oil and standard procedures, ensuring compatibility with the transmission type, such as dual-clutch or automatic. If the wrong oil is accidentally added, it might damage the components. Regular repair shops can do it too, and it's cheaper, but if something goes wrong, the warranty might not cover it, making repairs more troublesome. I once tried changing it outside, but the oil quality was unreliable, causing gear shift jerks, and later I had to redo it, costing double. Actually, the key is to find a professional technician for inspection. Although 4S shops charge more, their services are standardized, including fluid changes and full vehicle inspections, which save hassle and money in the long run. Remember to follow the maintenance schedule and don't delay too long, or even the most reliable place might struggle to fix it.
From a cost-saving perspective, I've carefully calculated this: Transmission fluid changes at 4S shops are typically 30%-50% more expensive than at independent shops, but it depends on the vehicle model. For new cars or those under warranty, I strongly recommend going to a 4S shop because they use specialized tools and genuine parts, avoiding issues like clogged pipelines or accelerated wear from inferior fluids. For older cars out of warranty, independent shops are a good choice—more affordable and flexible. I once had mine changed at a local quick-service shop for a few hundred bucks, but make sure the mechanic is experienced enough to check fluid levels and seals. Don't just chase the lowest price and ignore the consequences: Using the wrong fluid could fry your transmission, and repairs can cost thousands. I recommend regular fluid changes instead of waiting for strange noises to appear. Compare options, like buying genuine fluid and having a shop install it—this can strike a balance. The key is choosing a reliable place with proper maintenance records, which also adds value when selling the car later.
I personally enjoy tinkering with cars and have even changed the transmission fluid myself. To be honest, DIY isn't difficult—buying genuine fluid and tools only costs a few dozen bucks, and there are plenty of tutorials online. However, the risks are significant: the first time I didn't pay attention to measuring the fluid temperature, overfilled it, and caused a leak. Luckily, I stopped in time. The advantage of dealerships lies in their professional equipment and training—they can precisely match the fluid type and quantity to avoid mistakes. For regular cars, getting it done at an independent shop is fine; just find a reputable one to save some money. The key is to pay attention to the fluid brand and change intervals, which are all specified in the manual—never delay. If you insist on going to the dealership, I think it's more worthwhile for new cars or complex transmissions, as the lower failure rate ensures peace of mind. Changing fluid really comes down to confidence and resources—for simpler models, I'd recommend doing it outside, but for more complex ones, it's safer to go the official route.
