Your cars transmission fluid is very susceptible to wear. When it wears it begins to break down and causes dirt and debris that eventually causes transmission failure.
Extends the life of the car, prevents a major repair, provides smooth operation and a solid feel that can be lost with wear and neglect and gives you peace of mind about your cars dependability.
It is common to see repairs that cost between $1500 and $4000. Additionally, the car is out of service for several days. The inconvenience and expense of breakdown and towing also has to be considered.
Normal service change fluid every 30,000 miles or once a year. For severe service (which is cars operated in a lot of stop and go driving or in severe weather conditions-extreme heat or cold or vehicles that tow) fluids should be changed more frequently. When visually inspecting fluid it should be clean and have no burned smell.
