Yup she's not but it also depends on how the tranny was built. How the bearings were setup. Tight/loose. Go with Justin's his is a daily unlike mine which is a weekend warrior cause I don't like to spend money on 91 everyday haha. GO GEO!

BTW have you ever considered Royal Purple Gear Max or synchromax? I ran gear max and it was pretty good stuff. I think the synchromax is a bit thinner but more thicker than synchromesh

Shep and TRE both say MT-90, Jack says EVO MR 6 spd fluid and TRE says its a good alternative if you cant find MT-90. All 3 agree on the Heavduty shock proof in rear diff and T-Case.

This is a quote from TRE:
"There are concerns about using Redline's Shockproof type gear oils inside manual transmissions. While this is truly an excellent product, it has been found that the heavy paraffin-like particles are quickly centrifuged out of the oil and build up inside the center diff housing and around the synchronizers and inside of the gearshafts. After several oil changes this build up may block oiling passages inside the gearshafts that lubricate the needle bearings and can reduce the overall effectiveness of the synchronizers, leading to poor shift quality. Therefore we do not suggest using Shockproof in the transmission unless the transmission is to be serviced often or a dog box."

Here is a quote from Jack:
"DO NOT use Synchromesh, BG Synchroshift I or II, or Royal Purple. These fluids will destroy synchros and gears and void your warranty! "
