Honda Gurus - What trans is in my car?

I picked up a '97 Civic DX coupe. It hasn't had an easy life, from the looks of it has a 1.6 from the wreckers out of a 2000 Civic (that's what was in grease pencil on the valve cover), but the trans is much greasier than the engine, so I am thinking it might still be original. The only thing is it feels way more peppier than my '98 DX did, and makes my '90 CX feel like I am starting off in second gear. It revs through 1st and 2nd like an Si. Can someone figure out from some rough data if it's a DX or an Si trans?

Tire size 185/65/14 = 23.46 inch diameter.
2000 RPM in 4th = 60 km/h
2000 RPM in 5th = 72 ish km/h

The thing about Honda transmissions is most of the parts are swapable so even is we had the case markings I could not tell you for certain what you have.
Those speeds with stock tire size sound normal so I'd say you do not have the (Canadian D series) SI transmission. So you most likely have the original DX box. And compaired to the DX your CX is starting off in second gear.

Thanks! I have been driving the CX for long enough now that I guess I am just used to it, and next to it pretty much ANY Honda feels a lot peppier. I am worried this DX will spoil me into wanting to keep it, it has crazy new fangled options like - a stereo, seats without massive holes in them, and these crazy buttons you can push to make the windows go down - what is this sorcery??

A 2000 and a 97 are the same gen, so nothing too major. what engine is in it? My trans is much dirtier also, and its stock, so thats no tell. Best guess is its a EX trans, the rpm's should be about 100rpm (87 to be exact) at those speeds. The rpm should be 1912 for an exact at a "true" 72kph though (dx at 1825).
