Mazdaspeed transmission? how can you tell it is one?
 

How can you tell if a 6 speed transmission is a mazdaspeed or regular? Any visual cues? I searched and couldn't find this basic info. Thanks

EDIT: Reread your post. Disregard.

are there any quantifiable differences?

durr: gear ratios

VIN tag on the side.

Vin #

Called up mazda and they verified easy peasy. Thanks guys

take it apart and sawzall the input shaft.

With the bell housing facing toward the firewall remove the 19mm? bolt on the right side of the trans. Inside Mazdaspeed will read like the bat signal. This is normally much quicker than the sawzall to input shaft methodology.

I lol'd IRL

I can't seem to find this bat signal, but I simply typed the VIN on the trans I received the other day into Google (just for kicks, I trust that it's a MSM trans as it was bought from a reputable member) and it came up as a 2004 MSM.
