what tranny is it??

hey fellas i just bought a DA shell last night as a parts car and with it came a tranny

im not too sure what tranny it is…

it has the vin #: S1-1026332

i think its a jdm b16?

help would be greatly appreciated!

Find things saying S1 trannys could be JDM B16 X-Si or USDM b18a. Doesn’t say anything else about how to tell.

^Yup. No way to tell w/o driving it or pulling it apart to count teeth and calc the ratios. Btw, the numbers you’re seeing on the trans case have nothing to do with a VIN. Only the newer transmissions had a VIN tag on them, the older ones have a number but it isn’t a VIN.

actually there is a way to tell. you turn the input shaft a certain number of revolutions and count how many times the output shaft turns in relation. unfortunately, i don’t recall the specific numbers. but it is a method that, in theory, should work

ok cool ill try that method. because i dont wanna switch trannys and have both of them be ls’s lol
