Looking to install the B-series trans into the Integra this week, trying to decide what to use. I've been using Honda MTL. - GA

MTL, pisswater thin, doesn't hold up very well.
What fluid does the diff maker suggest?
5w30 Synchromesh + 1/3 tube of Posi additive is what I used with my Kaaz, JBH also used it in Pebble. IMHO it would bee too thin due to the heat you will be seeing.
I've wanted to try 15w40 for diesels with their extra additives before it is phased out as well.
tGA, these are simple creatures. For what you'd pay for Torco RTF ($21/quart) you could use 3x Synchromesh ($7/quart) or 8x 10w30 ($2.50/quart).

I tend to agree with the above sentiment. Even though the trans was out only to replace the clutch, I asked Kessler to pull the case cover and check out the innards; I had driven it pretty hard at the race at the Glen with that bum clutch.
Since posting above I got the news: da innards was ugly. 3-4 syncro hub and sleeves were "toast", and 1-2 and 5-R looked like they had 60,000 miles on them. I did drive it pretty hard at the Glen, but with a very similar technique as you would without a clutch, patience going up and zipping the throttle going down. There was some "conflict" in the process, but what I saw on the 3-4 assembly resembled more years of street abuse than 45 minutes of racing abuse. And, the 3-4 upshift always "grunched" on me a little bit, even when this trans was new (I bought the ITR trans brandy-new from Honda in 2010).
I'm replacing 3-4 syncro assembly and will try something different than Honda MTL; I like your syncromesh+additive above. I'll contact OS Giken and see what they recommend for their LSD.
