Gearbox maintenance, especially automatic transmission maintenance, is a matter of great concern to car owners. Only once in several years. I have no experience. I'm afraid of being cheated and charged more money, and I'm afraid that the gearbox will have more problems after maintenance.
Most of the gearbox is wrapped in an aluminum shell. Only a small part of the oil pan can be removed from the vehicle bottom. If there is a problem with the gearbox, the gearbox needs to be disassembled in most cases. Many small repair shops do not have the ability to repair the gearbox at all. However, the quotations of 4S shops, large repair shops and gearbox repair shops are quite different, which leads to the car owners having no clue when choosing the gearbox repair site. The following section summarizes the problems that may be encountered in the maintenance process of the gearbox, hoping that the partners can bypass these pits in the maintenance process of the gearbox in the future.
1： False propaganda
Enterprises through the website to find pictures to combine their actual pictures to fake their own door, let people look tall, but the actual situation is really like this? What's more, what brand of oil is used for gearbox maintenance, and how much money you spend can be appropriately ranked.
2： Quotation trap
Where my gearbox is broken and how much maintenance costs are the concerns of the owners. If it is a telephone inquiry, it is difficult for the actual maintenance party to make an accurate estimate. Some companies just offer a low price on the phone and leave the car behind. There are many familiar routines. The owner of the repair shop will tell you that these are small problems. A screw may be loose. Come here and I'll tighten it for you
3： Act before you act
This pit is built on the basis of the second pit. First, the car is deducted at a low price. For example, the maintenance company clearly knows that the market price is around 10000 yuan. They tell you about 7000 yuan, and then tell you how much it is. It's not accurate now. It needs to be disassembled to give an accurate quotation. After taking it apart, I will tell you that the valve body is broken and the friction plate has worn so much. It will take 15 thousand yuan in total. If you don't repair it, you'll have to pay 3000 yuan for disassembly and inspection.
4： Maintenance Outsourcing
In the field of gearbox maintenance, this kind of pit is no longer a pit. It seems that a very large repair shop does not necessarily have the ability to repair the gearbox. Even the 4S shop does not necessarily repair every gearbox by itself. Gearbox maintenance outsourcing is now a very common thing. The repair shop only acts as an intermediary in the whole repair process. After the customer delivers the car for repair, the repair shop will transfer the gearbox to the small team specializing in gearbox repair to earn an intermediary fee. For consumers, it only costs a part of the money.
5： Warranty coverage
Many repair shops and 4S shops repair which fault in the warranty mode. If other gearbox faults occur during the warranty period, they will not be covered by the warranty. Even if the same problem occurs, some unscrupulous repair shops will falsely claim that they are caused by different reasons because consumers do not know enough about the gearbox. Transmission, especially automatic transmission, is a very precise mechanical structure, which can move the whole body by pulling one engine. Careless and careless maintenance may bring various problems to the gearbox in the future.
The above five points are often encountered in the process of gearbox maintenance. If it is found that a maintenance plant attempts to set a trap for you with the above method, please choose carefully.
For the maintenance of the gearbox, the core reason that most car owners are trapped is that they don't understand the gearbox. Of course, it is also very unrealistic to ask car owners to understand transmission knowledge. In the process of gearbox maintenance, the way to avoid stepping into the pit is to ask a professional.
