Some modern transmissions do not require oil maintenance because they are filled with lifetime fluid that supposedly last the lifetime of the transmission.
The eCVT in hybrid cars have electric motor/generator sets in it which the engine and regenerative brake system uses to charge the hybrid battery. A wrong transmission fluid in it will cause short circuit, malfunction and damage.
There are simple tricks that will reduce the amount of money spent on regular engine oil change. The money saved on a long term depends on the quality and suitability of oil used.
A bad wheel alignment causes a car not to track straight and it has other detrimental effects. It is caused by potholes, bumps, worn suspension and steering components and other kinds of impact on the wheels.
The choice of the use of synthetic or mineral engine oil is also a choice between long term cost saving and short term cost saving on servicing. It is more cost saving to use synthetic oil since it has longer oil change interval.
Preventive and corrective maintenance on a used car that is just purchased is important since buyer might not have all details of maintenance history and sometimes, people sell their cars due to faults without full disclosure.
The dipsticks of engine oil and transmission oil look similar, they also have upper and lower marks but the meaning of those marks and how they are read differ.
Coolant can gain access to transmission through the transmission oil cooler. The oil cooler can leak internally causing the coolant and oil chambers to be linked.
Coolant getting into the engine lubrication system can cause damage to the engine. It is mostly caused by a faulty head gasket, bad radiator that has oil cooler integrated in it or a bad engine oil cooler.
