i took apart my old XSI lsd tranny and it looks like right behind the diff the tranny case had been ground down to make it fit. not sure why tho.. the reason im asking this is because im putting that lsd into a stock cable b16 tranny and if i need to do that grinding of the case ill prolly skip the lsd prosses. thanks for your help

A pic would probably be good though

those are the pics. also there were no shimms in the tranny at all. will i have to shim the other b16???

Check out this "How-To" and I think you will agree someone put a 94-01 carrier in your YS1 case.

Nice find, i was curious myself. That about clears that up

Actually, all the YS1 transmissions with factory LSDs have the case ground like that. Mine is like that too, fwiw. If you are putting that LSD into another YS1 case, you'll need to grind down the fins.

That would be interesting.... I never heard that about the factory JDM YS1, but it is a very common mod that is needed to swap internals as it shows in that "How-To". Maybe if the factory modified the JDM YS1 cases for the optional LSD, then that might be where the idea for the "How-To" came from.

Either way, you are correct, if he plans to use a USDM YS1 case it will have to be modified to fit that LSD just like the one he pictured.

im not using a ys1 im using a j 1 b16 will i still need to grind that down?

iwantspeed

ok i have the lsd in WITHOUT grindind down any of those oil flow ridges. and it spins fine. do i still need to grind them down for any reason, and WHY do i need to grind them.

i have a jdm J-1 b16

iwantspeed

i tightend the case closed and it rubbed so im gunna notch the edges a little. it barely rubbed.

Sorry no replies sooner, but it has been a busy week.

It wasn't clear exactly which 2 trans you were talking about at first. You referenced to them by engine and trim level not actual trans code. IE - XSi, B16, vs. YS1, J1, Y1, etc... The only XSi trans that I have seen any documentation, or mention of, with a factory option of an LSD is the JDM YS1. Now it is very possible someone added an OEM LSD to the trans you had. Never seen any mention of a JDM J1 with the optional LSD. So just to make it clear for anyone reading this you have 2 trans:

1) JDM J1
2) ??????

Whatever the case may be, the check/fix is exactly what you have already done. I probably would have said notch it anyway since it won't hurt and the trans wasn't designed with that LSD in mind so you may as well while you have it open. Also as you found out, it is the same situation as in the link above, the carrier needs some added clearance inside the case.

actually i did grind it and put it all back together and it works great!!! thanks for all the help. im letting the sealent dry over night then mounting it on the motor. LSD FTW
