i know its gonna be a dumb question and i searched to but not enough time to go through 9866845234 pages. i know about the d series trans swap and i picked up a 5 speed from a crx si. it was on a d15 so i know it will fit, but my real question is the spline inlets are the same on all d series trans right? the inlets i speak of are the ones from the half-shafts to to trans? i think if i remember correct the only differences are the spline counts to the hubs, not to the trans on a d series. answers asap would be great.

ok i get it, the only thing though is, that there is no specified forum for trans swaps, and the one about motors has nothing to do with trans swaps, anything goes right, ok thought so. flame me i can give a ---- less, just please answer my question.

 

need answer asap guys.......

 

88 = 21 spline
89-91 = 20 spline

Also on the input shaft, no = 88, one groove = 89, two grooves = 90-91, there is a pic somewhere....I don't have it handy.

 

what is ment by groves man........groves dont mean much of anything......lol

 

ok nevermind i get it by the "grooves" term. it has two grooves(my spelling correction as well). so that is settled, its a 90-91 trans. now what i need to know is will my clutch from the 4 speed work with the 5 speed. let it be know im still learning about these cars, still reading a lot of ---- about them. but is the clutches teeth the same on both transmissions?? i really dont want to buy another clutch after i just bought this new one i got on it.....with the 4 speed.....

 

Well how many splines is the 4sp clutch?Your answer is there.
