Swapping gears question!!

hey guys, my friend is getting a motor swap in his 89 civic hatchback DX 5 speed.. and im wondering if im able to swap out his reverse for mine since that mine isnt working. is this possible or does the entire transmission need to be swapped out?I have a 90 crx si.thanks!

To swap the reverse gears,you would have to take out the tranny and open it up to have access to the gears.
Unless you have already done this and know for sure that the gears are the same,I say don't do it,just swap the tranny.

I believe you can just take the tranny apart and take his reverse. If he's getting a new motor, why dont u just take the whole tranny?? or did i misread it? :confused:

Well no u read it rite man...Is my car gonna be slower if i use the dx tranny..cause i like my high gearing:)

Oh i forgot to add this...yeah he is gonna give me the whole thing!

I'm not sure but maybe the diff gearing is higher on the dx,meaning you'll rev less on the highway and have a higher top speed,but I'm not sure about that.

I think you will have more top speed yeah. I hit 80 MPH in third while my friend in his DX hits well over 92 MPH. So i guess in a way it could make it slower but you would be able to keep the speed in each gear longer. Im not real sure though. :(

Yeah as long as it bolts up to my si motor i guess i won't sacrafice that much power? Hey would it be better on gas though? Well this is only temprary anyways. I have my b16 sitting here waiting to be install but i still gotta wait for Spring time and wait for like wiring harness etc...:)

Ok i told this guy that i'm getting a dx tranny for free. He said he thinks it won't fit cause its a 1.5 liter? I told him all d-series should fit. Its from an 89 hb. I just wanna make sure if it does fit...so is he rite or wrong?

D-series are interchangeable,except for 88 which had different input shaft spline,if I remember correctly.

But i can still switch gears from it rite? Cause i really need that reverse!

would be easier to swap the whole tranny.

Yeah i just wanna double check if my friends is an 89 hb.But if its an 88 then i'm just gonna get his reverse?

hay just get the revers gear ur 1/4 time will be higher with the dx trans the gears are to long si are short and will pick up faster than the dx the revers gear should swap theres no difference in them only the forward gears and the final drive are diff iff im wrong corect me

Yeah another friend of mine says he has a 91 si trans. So he's gonna give it to me but the thing is i think he said the bell housing is chipped so he's gonna switch gears for me. I told him that my 2nd ,3rd and 5th gear is bad also. So i guess we gonna switch all those gears also plus with a jdm final drive ratio of 4.44 :)
