Heat is no less difficult test for a car than frost. In addition to thermal loads under the hood and in the friction components and assemblies, a high ambient temperature is added. And in this situation, various problems can begin to creep in. For example, malfunctions in the operation of the automatic transmission begin. But what causes them if one of the most important parts of the car is to show endurance and endurance?
Our portal “AvtoVzglyad” found out why the heat can adversely affect the “machine” and how to avoid negative consequences. It’s sad, but true – the heat is just as damaging to the car assemblies, as is severe frost, and low-quality oil, and infrequent maintenance and non-genuine spare parts. If it’s +30 outside, the problems can occur one after the other. For example, noticeably losing grip due to the heat of the car. There are problems with the air conditioning and engine cooling system. The brakes may fail. Yes, and the automatic transmission can’t stand it and behaves strangely. Let’s talk about her.
To begin with, an increase in the temperature of the oil in the transmission, accompanied by various failures in the operation of the unit, if it happened before and did not depend on the onset of heat, is a rather serious symptom that promises problems with the box. And then – expensive repairs. There are many reasons why the transmission fluid temperature rises. Here is the drop in the oil level itself, the drop in operating pressure and the banal wear of the fluid. As a result of such problems, the oil can heat up more than 120 degrees, which is detrimental to the “machine”. The fluid degrades even faster, exacerbating gearbox wear. And here, not far from the breakdown of the solenoids, clutch pack and other transmission elements.
However, in the “machine” there is protection against a fool – after he sensed that something was wrong, the electronics usually put the transmission in emergency mode, which is reported to the car owner by a warning light on the dashboard. And in this situation, it is important to stop the gearbox operation, call a tow truck and take the car to a technical service. Otherwise you can get a lot of problems and then you can safely order a new gearbox.
Yes, in the heat, the ATF fluid that circulates in the box, lubricates and cools it, loses its properties. For example, with increasing temperatures, the viscosity deteriorates, which directly affects the elements of the gearbox that rub against each other – accelerate their wear. That is why many of the automatic transmissions have a cooling circuit installed. But if there are problems in the cooling system of the engine and gearbox, for example, an insufficient amount of coolant, then the transmission will certainly warm up. And if the car is stuck, stuck in a traffic jam or is being used at the peak of its capabilities, the overheating warning icon on the dashboard won’t be long in coming. And it will be followed by an expensive repair of the device. Or even replace it. And believe me, at the current prices there is little nice about this.
If the “machine” of your car has ever given you a signal, until the reasons are clarified, you should refuse to travel or make them when the peak of the heat has already passed. Do not neglect the maintenance of the “machine”. Change the transmission fluid in a timely manner and repair it so that problems do not accumulate like a snowball in a hot summer.
