I've been working on automatic gearbox maintenance for more than a decade, and i've seen too many car owners shoot their thighs to regret。
A lot of people, with the idea that a car can drive is not bad, turn a blind eye to the anomaly of the dashboard, the slight variation in the change of screen, and think, "just get on with it and fix it when it's bad." but the shift box is a "precious component" and a two-and-three-month delay could lead to a total level of damage -- thousands of things that would have been solved, and tens of thousands of dollars would have to be replaced with extra tolls and delays。
According to our three-year-long fail-out schedule, over 60 per cent of the cases of severe damage to the gearbox had a clear warning signal for one or two months before the outbreak, although the vast majority of the car owners had taken it seriously. Today, the most easily neglected 3 symptoms of failure are presented with a comparison of the cost of repair, and the owner of the vehicle can save a lot of money against himself。
+ slide: the most common wear and tear warning, not to be a “normal phenomenon”
There has been a consistent saying on the internet that “a bit of a setback in the automatic gearbox is normal”, and that's a lot of car owners。
First of all, let us be clear: the slight setback caused by the plant's retrofitting, which only occurs at a certain point, at a certain level, and has existed since the start of the new phase; if your vehicle has been smooth for tens of thousands of kilometres, there has been a sudden increase in the number of blockages, break-ups, even when it comes to stepping on the gas, and the slow pace of the car is not a normal phenomenon, but a clear warning that the speedbox will slide。
Many car owners feel that “just occasionally shakes, and it doesn't affect the drive”, but the wear of the friction sheet is irreversible, and it increases once. In the early periods of setbacks, most of them require the cleaning of valves, replacement of worn frictions, and maintenance costs are generally in the order of several thousand dollars; once they are dragged to the friction tablets, they are completely burned, shredded with broken valves and planetary gears, they can only be overhauled or even replaced in total, at a cost of three to five times more than the cost, which is set at tens of thousands。
Ii. Unusual noise + oil spill: dangerous signals can be seen
A number of drivers are insensitive to the sound of the vehicle, and they always think, "the car is old and noise is normal," but the transmission box is never "old noise" but rather a direct signal of damage to the internal parts。
Different acoustics correspond to different faults, so the owner can simply check himself:
More likely to be overlooked than the sound is the oil spill from the gearbox. Many of the car owners saw oil marks on the ground when they stopped, and felt that it was a very dangerous perception that it was “just a little missing, not affecting the drive”。
Automatic transformer tanks rely entirely on pressure-control switches, oil from transformer tanks is lubricated, the oil spill directly leads to insufficient pressure, unpositioned, and the internal parts are subject to sharp wear and tear in a short period of time. Each month, our store receives a dozen vehicles that are dry inside the gearbox and lying directly on the road because of oil spills, which would have required only a small failure of oil sealing and sealing, which would have turned into a whole box of scrap and would have cost more than a dozen times the maintenance costs。
Iii. Break-in + delay: distress signal for valves and electromagnetic valves
There are also typical signs, many of which are inappropriate: when you're stuck, you're cut from p to d, you're cut from d, you're out of r, you're gonna get a "scrambled" and you're gonna have to wait two or three seconds for the car to move, and if you're serious, you're gonna have a jump, a lock。
This is essentially the case with transmission tanks containing electromagnetic valves and the unstable oil pressure caused by the grinding of valves, which is an early failure of the electrical control system. The cost of maintenance at this stage is low, and most of it requires the cleaning of valves and the replacement of malfunctioning electromagnetic valves, which is typical of the “small cost of doing great”。
If, however, the continuous wear and tear of the valve leads to a total outage of oil pressure control, with an impact on internal gears, friction plates and eventually on the entire electromechanical control unit; in serious cases, there will be sudden jumps and locks in the movement, very dangerous at high speed, and maintenance costs will increase directly from thousands to tens of thousands。
Four, 90%. The owner stepped on three gearboxes
Wrong zone 1: don't worry
The normal restructuring setback is “new cars have a stable pattern”, and the failure setback is “late and more frequent”. As long as it's a setback or a noise at a later stage, it must be a precursor to a malfunction. There's no "just open" possibility, but it's only going to get worse。
Mistake 2: change as much gear as you can
Many stores sell “30,000 km of recyclers for oil” and, in fact, the cycles of fuel change in different transformers vary widely: at transformers are usually replaced by 6-8 million km and cvt, double-laying are replaced by the original plant manual 4-6 million km. Excessive oil exchange not only wastes money, but irregular recycles may also flush out valve impurities, causing malfunctions。
Wrong 3: any repair plant can fix a gearbox
The gearbox is one of the most sophisticated parts on the vehicle, with hundreds of spare parts in the interior, which are extremely demanding for technicians and specialized equipment. Most technicians in general complexes only know basic maintenance, rarely decomposing repair gearboxes, and are prone to “misdiagnosis, mischaracterization and deterioration” and wasteful money。
Like we're specializing in the retrofit box, the field amphibious market for more than 13 years, which is an automatic retrofit box, and a compressor. Dynamic test tables, valve repair equipment, at, cvt, dct, various types of gearbox failure can be accurately checked。
We have always maintained transparency in our services: free door-to-door testing, clear quotations, visualization of the entire construction, site verification of spare parts, 98 per cent backtracking of the entire store spare parts, commitment to no hidden consumption, no double mark-up; provision of up to 3 years / 100,000 km of national union protection after maintenance, and off-site failure to settle damages across the region, so that the main vehicle can repair and use comfort。
The gearbox, which is about the safety of the vehicle, has a direct impact on its life and has never been a “work-for-work” component。
An early small omen may require hundreds of thousands of repairs; towed to a complete prowl would be to replace the sum of tens of thousands of dollars with the risk of half-way anchorage. Early detection, early overhaul and savings are always the best solution for the maintenance of speedboxes。
If you have problems with your car, too, such as frustrations, noises, slips, oil spills, don't drag. Professional work is given to professional staff, who are required to carry out a thorough and timely review, in order to spend less money and travel less。
