BITOG is addictive. Now I'm looking for a better tranny fluid.
'94 Mitsubishi VR4 twin turbo all-wheel drive 6-speed Getrag transmission. Modified engine ~550awhp @ 20psi. recommended fluid is GL-4/GL-5 SAE75W-85W or 75W-90.
The tranny was rebuilt about 13k miles ago and has been run on a 50/50 mix of Redline MTL and MT-90. The tranny shifts OK, but it's a little notchy. Notchiest when cold, then shifting smooths out a little after warming up, but it's still somewhat notchy especially at higher rpms.
I'm looking for something to improve shift feel while still providing good protection on the track.
So far, the list of oils other owners have tried:
- Pennzoil Syncromesh: Shifts smooth but oil comes out with metal glitter. Too thin for adequate protection?
- BG Synchroshift: similar to Synchromesh.
- Redline MTL & MT-90 mix. very common, but I'm thinking there must be something that shifts better
- Redline MTL straight. Shifts well, but doesn't hold up when things get hot at the track.
- Royal Purple MaxGear 75w90. Notchy when cold, but supposedly very good when warmed up.
- Royal Purple Synchromax. Supposedly good even when cold, but maybe too thin?
- Mobil 1 10w30 motor oil. Incredibly, this is actually recommended by a tranny shop. Supposedly shifts pretty good but I'm thinking there's no way a motor oil would provide adequate protection in my tranny?
No one on the 3/S (Mitsubishi 3000GT / Dodge Stealth) platform has ever heard of Specialty Formulations that I'm aware of. I'd never heard of them until BITOG but the reviews seem pretty positive. I'm wondering if the MTL-R or MTL-P might be a good option for me or if anyone might recommend something else that might be better than the Redline MTL/MT-90 mix I'm currently using?
