Some guy is selling me an Si tranny but i wanna know for shure that it is a Si tranny. Is their any number to look out for to identify the tranny? Thanks

 

Si tranny (Y21/S21/S4C)

 

Do you mean a SOHC SI or DOHC SI/SIR

 

oops forgot to ask that.

 

its off a 1990/91 Si. I saw it and in the front it has a sticker with L3 and some numbers.

 

Im pretty sure all SOHC trannys read L3#### is their a gold sticker on it, IM pretty sure it should have a vin number and from their you could decode it to see if it came from an si correct me if Im wrong

 

Look in my project thread, I posted two fool-proof methods.

 

88-91 civic/crx si = L3 tranny.

go with tippyman method. 2camvtec then my dx tranny is an SI tranny it reads L3####

 

Tippyman what page would it be on?

 

Should have a black speedometer gear inside for 89-91 Si transmissions as well as EX 4dr models.

EX 4dr models = 4.06 Final Drive
Si models = 4.25 Final Drive

They all say L3 on them even the 4 spd models

Then would it be A000 or B000. That is all I really know.
