Honda Manual Transmission Specifications & Gear Ratios

[California98Civic]

I don't know the part numbers, sorry. But in the table that leads this thread, you'll see that the speed sensors for the 5th and 6th gen civics are the same. And each submodel has the same one too. I got that info from the FSM manuals and several of the best established honda discussion boards.

EDIT: if you are referring to the speedo gear inside the tranny, then that's another matter. But i saw one guy measuring the 35mm and 40mm inner diameter speedo gears, the black and the white, and find their outter diameter exactly equal. Only the inner diameter varied. I would bet that's true of the fifth gen too, given how little seemed to change across the 5th and 6th gen trannys.

The VX has the white speedo gear.

Cool. Thank you. I'm going to start hitting up junkyards in the next couple of weeks and do the "4 th gear spin the tranny and count clutch / driveshaft revolutions" trick that somebody else already posted on this site. (Old mech, I think) Might just get lucky. . I got my d15b because the junkyard didn't know what they were selling (I didn't know what I was buying, either! Dumb luck! ) we'll see if lightning can hit me twice. ..

It's starting to look like Tony_2018 was right about it being easier to find a cx/vx tranny & rebuild it than source out these oddball parts!!

I think its best you find the hx tranny and rebuild the synchros. You can probably find them on car-parts.com

Didn't see this reply. But the reason why I suggest this is to save yourself the headache and guessing game on what parts will fit. For the 96 model I still suggest you look for an HX model tranny.

Good advice to avoid guessing about part numbers for the gear swap, unless required. But there is no guessing involved in swapping a fifth gen trans onto a sixth gen engine. It has been done countless times as a plain bolt-on, without any mods. I did it: a 1993 CX onto my 1998 D16 engine. Seriously, if taller gearing is the point the biggest bang for the simplest swap is the 1992-1995 VX/CX transmission. Check the table that leads this thread. The fifth gear is the same, VX/CX - HX, but the FD is far taller on the VX/CX. Just saying... it's true.

Cool beans. Didn't know that. It now comes down if he will be capable if spotting the CX/vx tranny.

Edit: he's looking into swapping out the final drive, not the fifth gear.

[vrmouseyd15b]

thanks to you both!! since money is a little tight, I'm going to have to put off buying another whole tranny, but I do know which one I want now!!!

On another note, I tweaked my TPS and timing at the dizzy, and now I can lean burn at 70 mph! ( still at about 2750 rpm ) check me out - the smiley light is my "econo" light:



If I do find a definitive partnumber for the final drive gear with 3.25, I'll share it here.
Thanks again, all!!

Very nice. 2750 rpm at 70 mph is about what you'd expect from the 97 LX trans with the 0.702 fifth and 4.058 final drive. But lean burn? Seems pretty impressive to be in lean burn at 70mph. I think basjoos does that in his heavily aeromodded Civic. But that's about it.
