how often are you suppose to change tranmission fluid in a car?

Answer 1

It depends on the application (like so many questions posed here, your owners manual provides the answer). Many makes have a 30k mile interval, some are 50k, some are 100k and some recommend never servicing the transmission fluid. Then there are makes like GM where every one of the intervals I justed listed applies depending on which specific model you have.

I assume you refer to transmission fluid that is in the gearbox, diff or rear axle. Check your user manual for service details. Most transmission fluid is drained and changed at 50,000 miles. Changing more frequent than listed in the service manual is a waste of money.

If your question refers to engine oil:
Engine oil renewal is dependant upon type of car and type of oil [ synthetic or oil based]. Engine oil change could be 3,000miles or 25,000miles depending upon oil type and vehicle type. Again check your user manual. Alternatively phone the main dealer and if the 'service dept' would give the service details .... most usually freely give the information.

Answer 3

Truth ATF is a life time fluid. But When it gets to hot just like anything you have to replace it. Best thing to do is get the system flush T-converter and all, and put in a full synthetic ATF. You should however change your filtter ever 30 thou, or so.

Answer 4

In most auto ttrans it's every 75,000 miles, but that includes changing fluid in torque converter as well as transmission and changing the filter.

Answer 5

I would say every 20K-25K miles would be a safe bet, but it's probably best to check your owner's manual. It would give you the exact mileage intervals to change all of your fluids.
