Calcium compounds are widely used. There are vast deposits of limestone (calcium carbonate) used directly as a building stone and indirectly for cement. When limestone is heated in kilns it gives off carbon dioxide gas leaving behind quicklime (calcium oxide).
How to Change Transmission Fluid. Transmission fluid needs to be changed from time to time in order to extend the life of the transmission, usually every 30,000â60,000 miles (48,000â97,000 km) (sometimes more â check your owner's manual for service intervals).
Another problem is that people often use the wrong fluid when they change it. This even happens at shops, trust me. Often times transmissions, even by the same manufacturer, will use different fluid and the wrong one can cause premature failure.Sometimes people use what is cheap, which can be a problem for the same reason.any mechanics believe, perhaps correctly, that if you wait too long (mileage, not color) you should not change the fluid because it could cause transmission failure prematurely; whereas if you had changed it regularly all along it would be ok. People differ on what that mileage might be, but let's say it's 100k miles.
