I searched through forums and couldn't find a direct answer to this question, but just wondering what USDM tranny (purchased new) can I use to replace my JDM S1 tranny?

 

you can use a 90-93 integra LS, good for turbo.

you can use a 92-93 integra GSR, good for naturally aspirated.

that is all.

 

there is no replacement for S1 tranny in USDM world. the 00 SI tranny is hydro operated, and that won't go in (yet) without major fabrication. the only one i believe that will fit is the tranny (cannot remember the nomenclature at the moment) from the 92-93 USDM GSR that has a B17 (good luck finding one!). what, syncros gone?! and no replacement, huh? that why i am waiting to get my 00 SI conversion with all USDM gear using most likely Hasport.

any cable operated b series tranny will work. ive got a y1 lsd for sale. the 92-93 gsr tranny is a ys1, i have one on my b18.
