I am going to be buying an Si tranny for my Si (has a DX tranny now) And I want to be sure that what I get is an actual Si transmission.

What are the proper markings to look for.

It will be 89-91 Civic Si Tranny, not an 88 since splines are different

Thanks

 

i would like to know that too! cuz i boutght a si tranny and i did my swap and put the tranny in and it was a freekin 4spd

 

man would that suck.

I hope someone has this answer

 

check the pass side of the tranny

where the axle goes in theres a fill 17mm plug

next to that theres a stamp on the trann case

if PL3/x000 where x=3, 9, 1, then its an Si

if PL3/Ax00 where x =3, 9, 1 then is a DX... DX trannies have a letter with numbers on the stamp

the year is told by the input shaft where the clutch goes into.... if the tip before the spindles has 0 grooves, is a 88, if 1 groove is a 89, if 2 grooves then is a 90-91

alos by looking where the axle goes in.. the differentials themselve are a lil more beefier on the Si, and its considerably ticker than the DX..............

 

Hey USDM,

Not to disagree, but I have been searching and found this thread (Pg. 2 at bottom)

This guy is saying that an

Si = A001

Dx = A000

And you are saying its

Si = x000

Dx = Ax00

I'm still confused

dude doesnt know what he is saying

i have blown many trannies and have built 2 Dx with Si final drive

i put x, wich is going to be replaced by the number in wichever case

if it has the letter and numbers its a Dx/HF/ etc

numbers only is a Si
