M5R1 question

[dschmitt5.0]

New to the mazda transmission.. Where is the drain plug and fill plug on this transmission. ( Manual Transmission) Any pictures would be great... Need to change the fluid. Cause i know the guy before me did not do anything to it... Thanks for the help...

Driver's side, about midway back. Drain plug it a big-ass bolt. If you can't find it you probably can't see well enough to drive. Fill plug is a few inches straight above. I have found filling in the vehicle easier to do if you remove the shifter and the fill plug and just dump fluid in the shifter hole.

Thanks man. Will regular ATF work

Mercon or Mercon V is the preferred fluid. Don't use gear oil, that is too thick for the tight clearances in those bearings.

The trans uses 5.6 PINTS of fluid. A little less than 3 quarts.

Yep.

Look for what's called "Dex/Merc" fluid if it's a '07 or older M5OD. '08-'11 calls for Mercon V.
