Two days ago, my friend li lai, i went to see the 120,000-km popular rush. The car began to shake like parkinson as soon as it accelerated, and the switch was accompanied by a bang. I couldn't help but laugh at his confused face: "what's the matter? Can't spare the $20,000?" i didn't think the guy would just throw out a 4s maintenance offer: $38,000! That's almost half the value of the car
Let's start with the gearbox thing, it's like the car's daughter-in-law. It's always ready for hundreds of thousands of miles. I've seen too many car owners stomp on the gas, and the gear tank oil is not changed for 100,000 kilometres. Isn't that what you're eating
The gearbox failure actually had a distinct "dignity period". If you find the car frustrated when you turn over 3,000, or if you switch the car with a slight "twirl" or even a slight slipper when you speed up... It's all calling the police! It's like an occasional pain in the body, ignoring it, waiting for you is a big operation. One time i drove on 318, and i felt like the gearbox was ringing, and i got all over the hill, and it cost me a month's pay...
The inner sense of the old gearbox tends to deteriorate rapidly as the mileage increases. I've touched too many automatic transformer oils, new oils are bright red, like wine, and 100,000 kilometers of oil, dark as soy sauce, and a smell of burning. In this case, friction chips and liquid rectifiers inside the gearbox were long gone。
From a technical point of view, the failure of the old gearbox falls into three main categories:
Computer control system problems: including sensor failure, poor beam contact, etc., repair costs of mechanical wear and tear between 500-2000 yuan: in the case of gears, axle bearing wear and tear, the cost of repair is 3000-8,000 yuan liquid rectangles and centrifuge systems: it's the most troublesome, often requiring major repairs or replacements at a cost ranging from 10,000 to 40,000
Data from more than 100 older vehicles tested on their own show that 73 per cent of vehicles over eight years of age with automatic transmission vans have experienced varying degrees of speedbox problems. In normal use, cvt transformers have an average maintenance cycle of 120,000 kilometres, normal ats of 150,000 kilometres and doubles of 100,000 kilometres. If the cost of repair exceeds 30 per cent of the residual value of the vehicle, from an economic point of view, i suggest that you put up with it。
In the sense of the road test, a healthy gearbox switch should slip like a silk stocking slips over the thigh, rather than the squeezing of the board. I remember an experiment with a 200,000-km passat, and it was like sitting on a washing machine
A few practical tricks for old car owners:
The day-to-day driving effort is made to avoid pressing on the oil doors and brakes, especially when the gearbox is not hot. 2. Periodic checks of the colour and liquid position of the transformer tank oil are carried out, and the colours become darker or smelly to replace 3。
After all, the old gearbox is unrepaired, and it's important to look at these three points: first, the severity of the failure, second, the cost of repair, and third, how you feel about the car. If the failure is minor, the repair costs are within 5,000 and you want to drive for more than three more years, it will be repaired. If it had been accompanied by a clear sense of shock and the cost of maintenance was in the order of tens of thousands, it would have been better to buy a second-hand car or to pay for a new car. I had a friend who insisted on repairing his old gunney's gearbox, which cost $32,000, and then three months later, the engine went to bed again...
Compared to the same type of car, the cost of major repairs to speedboxes in yakoh and camery is typically between $15 and $25,000, and in german cars between $20 and $35,000, while the national product plate is more than $12,000. But some of the special models of joint ventures, such as the cvt with a sports model or the double-disconnected gearbox, are built to buy gold。
Finally, ask yourself: is this car worth a few more years? If the gearbox is fixed, will the rest of the parts be connected like dominoes? After all, it's like changing the heart of an 80-year-old.
Are you gonna fix this? If it were me, the mileage was within 100,000, and the failure was not particularly severe, i would have chosen to fix it; more than 150,000 kilometres, there have been many problems, changing cars decisively. That is the most cost-effective option。
