^^^ Yep :/
I also use Redline MT-90 transmission oil (you must use the non-LSD type MT-90 oil). I have all the MC parts available except for the new 5th/Reverse fork from Driftmotion which wasn't available when I rebuilt mine. Replacing all the forks with the billet pieces from MC and DM is recommended. Someone commented on another CL thread that the majority of the R154 is built like a tank but the factory 1st gear thrust washer, front bearing retainer and all shift forks are the under built pieces that can be overstressed. But all of those can be replaced now with better parts. And still... this is a much, much stronger transmission than a W58.
Twin and triple disc clutches are supposed to help with transmission wear and avoid crank walk from a heavy single disc pressure plate. I have no experience with them to comment on. I'm still using am OEM 7MGTE clutch and pressure plate on my car while I'm NA (very cheap interim clutch for NA use). My understanding is that upgrading the clutch disc to an ACT or Southbend while still using the factory 7MGTE pressure plate keeps the stresses out of dangerous territory. Of course, that's only good for maybe 400-450whp. Someone correct me if I'm wrong.
The other thing with R154's and V160's is that on original manual cars the neutral safety switch on the clutch pedal must be disconnected and jumpered. Always start with the transmission in neutral. Reason being that this helps to prevent crank walk due to oil starvation on the rear crank bearing upon startup. W58's and automatics don't cause this problem, and 7M engines with R154's don't have the issue, just 1JZ/2JZ's with R154/V160's. Supra MKIV guys will also disable their NSS with either manual transmission.
