I was on aim and talking to someone from Honda-tech... he says he has 2 JDM YS1 transmissions, one with LSD one without. I was under the impression YS1's were not JDM units. Is this true they were/are JDM? The convo: Theoneinthe760Ca: i have like 4 jdm cables Integra1990Racer: wanna trade? Integra1990Racer: you pay shippin on tranny Integra1990Racer: i pay shippin on engine Theoneinthe760Ca: well Integra1990Racer: or motor Theoneinthe760Ca: see i have a j1 s1 and 2 ys1's Theoneinthe760Ca: i need 3 and i have 4 Integra1990Racer: ys1 isnt JDM Integra1990Racer: 90-93 Integra's came with it Theoneinthe760Ca: nope Integra1990Racer: USDM integra's came stock with YS1's Theoneinthe760Ca: the YS1 was also a JDM tranny Integra1990Racer: really? Theoneinthe760Ca: i have one with stock LSD and one with out Theoneinthe760Ca: both are JDM Theoneinthe760Ca: the 90-93 integ ys1 has a bigger shaft a hyrdo one Integra1990Racer: mmm didnt know that..... goin by the reference section on hondaswap.com it says ys1's were not JDM, USDM only Theoneinthe760Ca: its diff then the regular JDM bseies Integra1990Racer: 90-93 integras are cable trans. Theoneinthe760Ca: skip hondaswap some of they chet is wrong Integra1990Racer: Ill get it figured out Theoneinthe760Ca: i know but the diff between JDM and USDM is the shaft spline, the USDM has a hydro size one when the JDM has a smaller one like the rest of the jdm cables. This true?
