will a 1989 crx tranny fit in my 1989 civic si, what parts do i need?

 

yes it will, it will bolt on,

 

i heard something about using the crx clutch and pressure plate instead of the si, because the splines were diffenent, is this true?

 

Nope, 89 to 89 is the same, if you swapped years you may have issues. Direct swap.

 

what they both said.

 

same or better gear ratios?

 

anyone?

 

can anyone tell me if the ratios are the same in a 1989 crx tranny as they are in a 1989 civic si tranny?

If the crx is an si also, then yes, they're the same.

 

dude its the EXACT same drive tran just a different body on the car.

 

Still havent answered what model the CRX is....Is it an Si or a DX or an HF?? If its the Si they are the same exact trans as many people have said if its the DX its the same except the final drive is different if its the HF then its completely different gears.

 

not sure, the tranny just has a tag on it that says 1989 crx, how do i tell which one it is from?

 

anyone know ho to determine the crx si tranny over the base crx tranny?

 

Look at the numbers that are on the tag on the tranny then come on here do a search for the tranny codes and you will be all set. Si trannies are L3 than some numbers I forgot how exactly they are but it has been covered so if you did search you will find out about them.

 

crx si trannys should have PL3/3000 stamped above the fill plug(tranny fluid fill plug). and HF/DX/STD have PL3/A000 or PL3/A100.

so do you know how to tell then?

 

Theres a way you can tell by turning the shaft 10 times and looking to see where the diff ends up, but I cant find the damn site....

Edit : I have it saved but dont know the site....heres how you do it.

Put the tranny in 1st gear.
Rotate the shaft till the diff is at 12 o' clock.
Rotate the shaft 10 full rotations clockwise.
Si = diff at the bottom left, between 7-8 o' clock.
DX = diff at the top left, between 10-11 o' clock.
HF = diff at the top right, around 2 o' clock.
