😔 Warming up ATMs!!
▪️ If the oil of the automatic transmission is in optimal conditions, if it has the correct level and is clean, it should not overheat, and therefore its operation will be normal.
In certain operating conditions, the driver may face the fact that the transmission starts to have overheating symptoms.
▪️Symptoms of heating:
1. The smell of burning
2. Oil burns and takes a black tone real quick
3. Hot skate accelerate and not forward
4. Warning on transmission failure dashboard
5. Eventual or continuous bumps
6. Loss of strength
7. Not gearing up any speed
8. Delay in departure, you connect and don't forward
9. Late in retrospect
10. Vibration or vibration, car vibrates at a certain speed
11. Accelerates and raises excess RPMs (Revolutions per minute)
12. The car pulls up
▪️ Ignoring these symptoms shortens the lifespan of the automatic box. Overheating will cause faults which will be evidenced by the check light (not in all cases).
▪️Most of the causes of an automatic box heating are:
1. Low oil level
2. Dirty oil
3. Wrong oil
4. Low quality products
5. Extreme driving conditions
6. Very steep climbs
7. Assisting a car by serving as a tow truck (depends on the model of the car, sedan is definitely not for it)
8. We lay short roads with excess braking
9. slow speeds with little continuity
10. Excessive traffic
11. Accidental Topography
12. High ambient temperature, if the box is not properly conditioned
▪️ These conditions raise the internal temperature of the automatic transmission, in some occasions it reaches up to 120 ° C, and at that moment some cars stop gear, as a method of protection, but something burned internally.
▪️ Consequences of heating:
1. Valves and solenoids caught on fire
2. Burned records
3. Sensors are blocked or short
4. TCM out of order
5. Loss of power
6. Check lights on, AT, OD, TRANSFER FAIR, SLOW DOWN ETC.
7. Damaged hoses and retainers
8. Leak Stamps
9. Zombies
😉When the box overheats, in some cases the ECU (electronic control unit) can lock the operation and enter emergency mode. Limit the operation of the box to avoid major damage.
🤔 What to do if the box goes into emergency mode and doesn't walk?
Not always the box will enter emergency mode and stop, this depends on the type and model, generally the DCT, CVT and some Tiptronic, if it has this function, of locking. If the car stops and the box does not connect, you should wait for the necessary time, from 20 to 40 minutes in order to advance, but you must immediately attend an inspection.
🤔How do you fix overheating?
1. Always perform electronic diagnostics, to determine the temperature of the fluid, if it exceeds 70 ° C, you must already estimate to perform the service
2. Perform the service in a preventive manner
3. In countries with our GUATEMALA, the cvt from 20,000 to 30,000km, Tiptronic from 45,000 to 60,000km, DCT 30,00KM.
4. Wash the system with products certified for it
5. Use quality oils, and suitable for operation in GUATEMALA, as well as in extreme conditions of operation
6. Use proper mercon or dexron certification
7. Not every box you can use "LV" oils
8. Use full synthetic oils, but there are two, one high viscosity and another "LV" (low viscosity = low viscosity), LV should not be used, in many applications
9. If you can, you must stabilize the oil with certified additives, available worldwide, to help the IV (viscosity index) remain stable.
10. If it already has a failure, there are "N" quantity of products worldwide, which eliminate failures or damage in automatic boxes
11. Having a hydraulic cleaning system (dialysis machine) and adequate cleaners, the change of the filter, with some exceptions, is not necessary, for that already exist the right products and accessories for a quick and timely cleaning.
😀 Remember that many boxes were not developed thinking about the poor operating conditions of Guatemala, adding the lack of maintenance and poor quality products, THE HEATING, in many cases becomes inevitable.
😀Always remember to drive letting the car develop alone, in traffic or short stretches do not overspeed, do not overload your car, and do not move the charging battery incorrectly and (first positive and then negative) avoid generating a short circuit, you can damage an electronic component.
