So I was looking up different stages of transmissions when I ran across a site (Jacks Transmissions). Idk whether they're good or not but the main thing that caught my eye was the oils recommended for DSMs. It stated that, for transfer cases, don't use BG Synchroshift since it destroys your synchros and gears. I just wanted to know if this is true. It was referring to the EVO but I think it might have applied to DSMs also. Here is the exact quote if anyone is interested.
"DSM, 3S and EVO transmissions require 2.5-3 quarts of oil. For our DSM transmission rebuilds we recommend factory Mitsubishi 6-speed manual transmission gear oil from the 2005 Mitsubishi EVO MR. This is the best oil to use as it has the perfect blend of friction modifiers to keep the tranny shifting smoothly and prevent gear failure. Gear oil choice is very important and varies based on preloads and synchro blocker ring design, therefore it is strongly recommended that you stick with this fluid for our transmissions. If you are unable to locate Mitsubishi MR 6-speed oil from the Mitsubishi dealer, Redline MT90 gear oil will also work just as well. You can find this fluid here on our website.
For transfer cases and rear ends, use Redline Heavyweight Shockproof ONLY. It is especially important to use only Redline Heavyweight Shockproof fluid or Mitsubishi dealer t-case fluid in EVO transfer cases. DO NOT use Synchromesh, BG Synchroshift I or II, or Royal Purple. These fluids will destroy synchros and gears and void your warranty!"
I was thinking about getting Synchroshift II for my transmission which is why I'm asking. I think I've heard some people use it for transfer cases but I always questioned this. Either way, should I stay away from Synchroshift even if I wanted it for just my transmission? It's not a built transmission it's completely stock from what I know.
Also, does anyone have any suggestions on what oils they would recommend for my transmission and transfer case? Thanks in advance!
