How often should i really change my transmission fluid?

 

When the service schedule in the Owner's Manual says so.

I change mine once a year though.


.

 

rule of thumb i go by is about every 50,000 miles. once a year sounds like overkill to me but i guess it's better to be safe than sorry. though i just did a flush on a manual 05 corolla at 80,000 miles and it came out clear and gold. transmission oil isn't like engine oil that gets contaminated all the time so it's not as urgent, but if you got time, just flush it the next time you do an oil change, it's really simple

 

i dont htink my trannys been flushed in the 160xxx miles its been around lol

 

Automatic, I think Honda recommends change (drain and refill, not necessarily flush) every 30,000 miles.

Manual is not as critical. Do watch out for leaks on a manual; open the fill plug once in a while and make sure it's staying full. A lot of people don't even know there is fluid in a manual transmission.

 

i have also heard some horror storyes about flushing tranny fluid after 100k.. u have any insite to that mk?

 

ur right mk378 bout ppl not knowin theres tranny fluid in a manual. i embarrassed a manager at autozone one time cuz of dat. he didn't have a clue bout it. he kept naggin me dat theres no such thing til i showed him da bottle of manua tranny fluid. lol

 

Follow whatever the owners manual says for service schedule. If you're unsure when the last time the fluid was replaced, do it and stick to the mileage in the manual(for example if it says every 60k, do it).
