the ls ys1 and gsr ys1 were the only tranny's from the 90-93 tegs right? was there another ls that had longer gears? also the 94 up ls was a y80 correct? oh and how many qrts do i need to fill the ls ys1?

 

ys1 is from either gsr or ls
the gsr has a substantial difference in gear ratios than the ls
and the s1 is another tranny that was around in 92-93 but only in japan on the sir1. the ls tranny that is 94+ is a s80 and the gsr had either a s80 or y80 case and the itr uses a s80 case also.

your case holds about two quarts of oil. fill it per factory specs and you will be fine

 

yeah well i'm picking up a ls ys1 tranny tonight and just wanted to check. i didn't know what the factory fill was.

 

well just fill it until oil starts coming back out the fill hole and VIOLA perfect amount of tranny fluid

this is wrong.

the sir1 is an 89-91 engine, and has the earlier version of tranny, such as a s1, y1, or j1. The sir2 has a hydro tranny since in 92 civics became hydro.

all 92-93 integras came with "ys1" trannies. Doesn't matter if its rs/ls/gs/lss/gsr..... the gsr trannies have the shorter gears. The 92-93 jdm xsi's also had short geared ys1's. And I believe the 92-93 jdm b18a equiped cars also had ys1's.

usdm 90-91 cars had a couple different trannies, but never a ys1. Some have a1's, and I believe some have s1's. y1's and j1's were available in japan, but I don't think in the us. Also, the s1 has a jdm version with short gears.
