Honda recommends "Honda Genuine Manual Transmission Fluid". I've been using Amsoil Manual Synchromesh Transmission Fluid for the past 48,000 miles and have had no issues.

You should use Genuine Honda Manual Transmission Fluid. It should be available at most auto stores.

Automatic Transmission, 4T65-E AWD Initial Fill..........7.9 quarts
Automatic Transmission, 4T65-E FWD Initial Fill..........7.4 quarts
Automatic Transmission, Total Fill
4 speed 4T65-E FWD..........10.1 quarts
4 speed 4T65-E AWD..........10.9 quarts

You'll want to use transmission fluid marked as DEXRON in your transmision.

The mechanics lied to you. Changing the transmission fluid and screen will not cause any car not to run. Just as you need to periodically change the oil, the same holds true for transmission fluid. Though the fluid is black, yoou state that you have no slippage or nothing out of the ordinary. If that is the case, then you do not need a new transmission. Just have the fluid and screen replaced and all will be fine. Make sure to pick up a transmission pan gasket while you get the necessary fluid and screen. Again, changing the fluid will not cause any car to not run. It is safe to perform the fluid change.

Find the transmission filler tube under the hood. Get a funnel, and fill. Do not overfill, and use proper tranny fluid for your cars' specifications. Your user manual should have a capacities index, and the type of trans. fluid to use listed somewhere in the manual. Hope this helps.

When you go the autoparts store to buy it tell them you have a Mazda and they can look it up and tell you exactly which one, but probably Dextron 3 but confirm that.
