what is the recomended Millage to change transmission fluid?

I information can be found in the owners manual.

According to the manual every 30k 60k miles. Shop around for the best labor rate and get your parts from an Acura dealer (fluid, filter) don’t use some generic multi oil. Remember fluid is cheap, transmission and engine are not so if you can DYI do so I did mine at a local shop plus timing belt, water pump, serpentine belt, thermostat, spark plugs and transmission drain and fill for $500 labor and $400 in parts. Other shops wanted $5000 to do all of the above. I’m in Houston btw
