How to know when to replace automatic transmission fluid (ATF)

How to know when to replace automatic transmission fluid (ATF)

Automatic transmission of a car is very delicate and should be taken care of. It is very important to carry out oil change preventive maintenance on a car's transmission to ensure its longevity. 
Often, car users don't know when the transmission oil is due for change. This happens especially when the car was acquired as a used car and the mileage at which previous oil change was done is unknown. Furthermore, some manufacturers do not give any service mileage for transmission oil but state that there is "lifetime" fluid which does not require maintenance in the transmission. Users reviews have shown that some people have had troubles with their transmissions because they followed this recommendation and didn't change the ATF (Automatic transmission fluid).&..

Automatic transmission fluid turns chocolate brown

Automatic transmission fluid turns chocolate brown

Automatic transmissions are very delicate part of automobiles. They ought to be handled with care and owner or users ought to have a good level of maintenance culture.
One of the practices that kill automatic transmissions is the use of incompatible automatic transmission fluid in the transmission of a hybrid car.
Automatic transmission fluids transform in different ways depending on the cause, ranging from age, overuse, water intrusion into the transmission, transmission overheat, clutch wear, incorrect fluid and so on. ..
The one we shall discuss here is quite uncommon and that is automatic transmission fluid looking like chocolate or mud.
We are going to be using a case study; a 2010 model Toyota camry hybrid.
Before we assessed this vehicle, the code that the vehicle was..

How to clean cooling system-that is contaminated with engine oil or transmission oil

How to clean cooling system-that is contaminated with engine oil or transmission oil

A very frustrating situation can arise where either the engine oil or automatic transmission fluid finds its way into the cooling system and mixes with the coolant solution. The oil will be present all over the engine, radiator, expansion tank, coolant reservoir and hoses. 
This can happen through the following faults;
Leaking cylinder head gasketCracked cylinder headFaulty engine oil cooler or heat exchanger Faulty transmission oil cooler or heat exchangerHuman error (pouring engine oil into the coolant reservoir or expansion tank)
Removing oil from the cooling system can be a very difficult task to accomplish and it is one that requires a lot of patience and perseverance.
Luckily, commonly available dishwashers are very effective in getting rid of oil from t..

How a poorly maintained cooling system can damage a car's transmission

How a poorly maintained cooling system can damage a car's transmission

There are some cars that have transmission heat exchangers attached to the bottom of the radiator. Mineral deposits as a result of prolonged use of water can go settle at the water passage side of the oil cooler and block it. You will then have only ATF circulating but not water and hence no heat exchange. This is the beginning of the end of such transmission.
As the transmission will be overheating especially during high ambient temperatures, sporty or high speed driving.
This is because there would no longer be heat transfer from the transmission fluid to the coolant.
The transmission overheats, oil gets burned, clutches wear out, solenoids overheat and gets damaged, electrical wires resistances increase and so on.
This can be prevented by ensuring that the cooling system mai..
