any hydraulic D-series tranny (the zc is an exception, but you
can make it work) from a 92-00 civic. Make sure it's a D-series tranny (SOHC!, not DOHC). If you have a z6, I would reccomend getting another Z6 tranny (92-95 EX/Si) or "upgrade" to a D16Y8 tranny (96-00 civic EX/Si).
Tranny's will have a code by the trans fluid fill plug that reads A000 or B000. A000 has small bearing case and B000 has large bearing case. So, B000 is better.
Here's where you can find the code:
A000's are from HX, DX, CX, VX models [gear ratios better for high end]
B000's are from EX, Si (SOHC only) models [gears ratio better for low end]
The Y8 tranny is "better" because it's composed of steel instead of aluminum like the Z6.
Also, the Y8 has one gear that has a
slightly higher gear ratio than the Z6.
Z6 M/T gear ratios: Y8 M/T gear ratios:
1ST: 3.250 1ST: 3.250
2ND: 1.900 2ND: 1.909
3RD: 1.250 3RD: 1.250
4TH: 0.909 4TH: 0.909
5TH: 0.702 5TH: 0.702
Reverse: 3.153 Reverse: 3.153
Final Drive: 4.250 Final Drive: 4.250
I recommend getting a B000 and a Y8 if you can get one.
