Red Line Diffy Oil
I did contact RL, but they did not believe my notchiness problem was the result of using their gear oil. Oh well, another customer lost
All have been forewarned about RL gear oil, so proceed at your own risk!

Redline MTL and MT-90 has no or almost no friction modifiers, thus the problem with notchiness that some of us have experienced. A friend of mine who had experience with the Redline MTL warned me not to use it in my transmission. I had already bought the Redline MT-90 for my transmission so I put it in. And I am sorry that I did. I may try to add the friction modifier I alluded to in my earlier post or just dump the Redline MT-90 in favor of a gear oil that already has the friction modifiers in it. I also plan to contact Redline as soon as I can regarding this issue. I've heard of way too many people having issues their MTL and MT-90.

Redline MTL (too thin) and MT90 have additives or modifiers that tend to increase grab at the syncro cones, for less crunch when shifting. They were among the first to offer this type of dedicated synthetic transmission oil.
Neo also sells this type of trans oil. In fact, GM, Honda Saab, Chrysler, and many others now provide this same type of 'grabby' gear oil for their new cars.
All of the these mfg's understand that conventional slick friction modifiers (for differentials) are NOT the thing to use in syncro transmissions.
It's possible that the slick stuff worked well for GS+, but likely for all the wrong reasons in his isolated case.

I have the MT-90 in my transmission and it is a little Rough shifting gears. I dont have anything to compare it with since i just did an auto to manual conversion. Im in the process on upgrading my turbos and fuel system so im going to switch out the fluid at the same time to redline 75w90 to see if there's a difference. Hopefully its the fluid causing the roungh shifting and not the transmission.

Usually, the 2nd+ time u change the tranny fluid it improves. THis is probably from removing more of the old fluid out.

RL>RP>Amsoil
Why?
2 years ago at SS5 I was at the Sunday event at Racing Beat and took one of the RP reps aside and we talked about synthetic oils and so forth.
We both agreed that Amsoil is shitty.
But when I asked him about Redline, he didn't say anything bad about them.
Now, if u think u had a better product, u would not hesitate to diss the other guys.
Gee, I wonder.........

HOW about RL Shock proof oil
I been use this on all my rx7 (2gen race car, 3gen daily)
SO far it doesnt give me any problem. I use heavey one on my race car, change once a year, still look like new when I drain it.

I'm using 250w RL shock proof.
That stuff is soooo thick. kinda like paste.
Make sure u let any excess drain out via the fill hole.
Or else u may have too much and that can force out of the seal.
