My new Buick Excelle had two transmission oil leaks in one year. The transmission oil pan gasket and an oil seal were replaced for the first time at the Nantong Changjiang Buick 4S store.
Now it started leaking oil again. I went to Nantong Changjiang Buick 4S store for inspection. The maintenance man just wiped off the oil, but the problem still existed. I think there is a quality problem with the gearbox of this car. I require the gearbox assembly to be replaced to completely solve the oil leakage.

Some people said that they won the first prize in gearbox maintenance. Maintenance competitions were organized by manufacturers, such as their 4S stores, to participate. For example, Audi’s annual double cup competition. Such competitions have never been held in an industry as fragmented as the gearbox industry. Another example is the fake internship base of a certain university. When you go in and find that there are only a dozen people in the company, how can you get such qualifications? Xin Fumei is also the Chinese maintenance and parts authorization provider for BMW and Audi transmission suppliers, and Volkswagen Regal and Toyota transmission supplier for Japan's Aisin. There are only two in China, one in Guangzhou and one in Xinfumei National Chain Store (Shanghai). Many colleagues actually claim to be authorized, which is really speechless. Some peers claim how many patents they have but do not provide proof. Fumei's website states that it has 29 national patents. You can go to the National Patent Network and enter "Shanghai Xinfumei Transmission Technical Service Co., Ltd." to verify. The seventh trap is promising attractive conditions. For example, some maintenance parties promise that all faults will be fixed on the same day, so you can do it. Ask 4S stores and regular brands like Huasheng. Who dares to say that? It usually takes five to six days. Without lifting the gearbox and disassembling it, the work that can be done is very limited. There is only one oil pan that can be removed from below. Ninety percent of them have to be broken up before they can be repaired. After investing tens of millions, it is something that even 4S stores with manufacturer support cannot do. Can a gearbox repair shop do it? There is no other explanation other than tricking people into coming here. The eighth trap: Not replacing new seals, not replacing new oil, not replacing vulnerable friction plates. According to the gearbox manufacturer's overhaul standards, after the gearbox is disassembled, various clutch seals, oil pan gaskets, etc. The seals are collectively called repair kits. Fumei replaces them in accordance with the maintenance standards of ZF and Aisin, but small repair shops will definitely ignore them as long as they can continue to be used in the short term. Fumei overhaul must replace the oil with new oil. In the Fumei workshop, car owners can see that the old oil is broken up and poured directly into the waste oil barrel. Otherwise, old oil and new friction pads will be mixed together, which is really a waste. However, small companies often save costs by keeping the old oil separately and continue to use it. There are some friction plates on the gearbox that are relatively easy to wear. For example, the friction plates in all torque converters are combined very frequently and at low speeds, so they are stressed. The shortest life span. The standard of ZF and Aisin is that as long as the gearbox is broken up, the torque converter must be cut open and the friction plate must be replaced. Small stalls don’t have any equipment, and 4S stores don’t have this equipment unless they are outsourced. Just ignore it. Another example is the input shaft friction plate of the Audi continuously variable transmission, the small circuit board of the Audi q5, and other components that are prone to problems and are not too expensive. Fumei's method is to replace them strictly according to standards. The car owner may have two questions: I just want to say that the materials used by Fumei are genuine, so how can I supervise you? I can’t just stare next to the master. The core is that when 90-year-old repair shops come to non-professional customers like car owners, they will reimburse them for repairs or replace them with warranty. When repairs happen, if you just say that another part is broken, the car owner will definitely not be able to blame him. They don't care about rework, they must only focus on reducing costs. The gearbox repaired by Fumei is guaranteed for all faults. If it is returned for repair and overhaul within the warranty period, there will be no profit on this order. Therefore, you must take full responsibility for the quality and not cause trouble for yourself. More importantly, gearbox problems usually occur after 150,000 to 200,000 kilometers, and these small parts that often have problems are almost gone. If these wearing parts are not replaced, the car owner will often have to overhaul it again soon after the warranty period is out. It's really a waste of money.
Bonus at the end of the article: Attaching a common routine of a bad businessman in the industry. Some colleagues in the industry rent one or two workstations in some repair shops in other places and hire two people, so they claim to have a branch. There are stores in more than a dozen provinces across the country. Then he brags about it online, but often changes his name. After arriving, they will check you first. Although you think it is unreliable, you do not object to them checking the problem for you. It is a common process to put oil in to see if there are any debris inside. Originally, only half a cup is enough. But as soon as they release it, they release it until it is finished. Then use various reasons to evade, such as poor communication and so on. Your gearbox can't run without oil. Refueling is expensive, and repairs are inevitable. It costs thousands of dollars to refuel, so you have to repair it here. They quoted a low price at first, but then they completely broke up. Just ask for a lot of money. To prevent this trick, pay attention to the following two points: After entering, if you see that it is a joint venture in a repair shop, or there is not much business, leave quickly. There must be a reason why business is not doing well. It's okay to check. You can only test drive and connect instruments to see the data. Don't let others put the blame on you easily. Be sure to keep this in mind.
