Well I've been checking in with my local JDM Parts/Engine supplier weekly and finally after 6 months of waiting a very new S20 LSD Transmission came in with a D15B. So I bought the tranny to put into my 98 hatch, but I had some questions for some of the tech savvy types who know the tranny.

What kind of fluid do I use? It doesn't appear to have a sealed diff housing so I would assume that the transmission fluid is shared with the diff and if thats the case then I would assume it's a helical type LSD which would use the standard 10W-30 or Honda MTF. I know with Viscous types of diffs they require a much heavier weight oil. I'm also assuming because the Type-R's use Helical LSD that this would be the same. Input???

Also I'm assuming that the Vehicle Speed Sensor is the same between my EK and this S20 so I was going to use the one currently in the transmission. Safe Assumption???

Thanks!

 

Wow no answers yet??? This tranny must be really rare because nobody knows anything about it.

 

Honda MTF would be a good place to start...I'm an EG/EJ guy, so I don't know about the VSS, sorry.

 

whats up. i bought the same transmission back in march 2009. it is the same type as a type-r "helical". i used honda mtf and a friction modifier to be safe. lsd additive. it feels like an r bseries tranny in the shifter, very firm and precise. never felt another d like it. nice short gears. i had a d16y7 with a few parts manifold etc. with 8lbs of boost. and a low rpm race to 60 with no more than 4000 rpms i pulled my buddies b16b ctr powered eg6 by a car or two.

p.s. it is very rare never get rid of it like i just did. but my buddy needed it for his 400 hp d series turbo build we are doing

hope this helps
