Is changing the transmission oil nessasary on an older car that is an automatic?

ALL vehicles new or old, require maintenance. Usually around every 30,000 miles/50,000 kilometers give or take, depending on the vehicle manufacturer for the service you mention.Is changing the transmission oil nessasary on an older car that is an automatic?
Yes it is because trans fluid breaks down just like engine oil. This can cause slipping or long warm up times also locking up of the trans. I recommend 12,000 miles or at least once a year. Depends on how much you drive it.Is changing the transmission oil nessasary on an older car that is an automatic?
Use the maintenance schedule for the car. As the car gets older the needs for maintenance increase.
It is a must to change both the fluid and filter on the transmission not only on an older car.,


See your maintenance schedule or consult your trusted auto mechanic.


Good luck.
In most cases no, but it does need changing if it is brown in color


It smells burnt


It ( the trans) is slipping


Most trans fluid will last well over 100,000 miles
Thats like askin if a gallon of milk lasts forever! ALL fluids in an automobile need changing at some time or other!
yes every 50000 miles with a new filter . cost about 75 dollars at wal mart
Necessary not really! In fact I have seen it cause problems shifting if it has never been done, because the new fluid is ';thinner'; than the old fluid that was removed. The filter should be changes to help performance about every 50,000 miles. But again I have has some cars that I never did either to and have have gone over 100,000 miles.
yes if you want it to last
It's necessary on any automatic transmission, every 40 to 50,000 miles it should be changed along with the filter.
yes, but it's usually done at a greater number of miles than a motor oil change.(maybe at very 15,000 miles?)


And when you do a tranny fluid change, you also replace the tranny fluid filter.


The reason you need to do it is that small microscopic shards of metal build up inside the fluid. Also, the viscocity of the fluid begins to break down as well.


But, all the old cars I ever own leaked all of it's fluid, I never need to change it.
