Motul Motylgear 75W90 ? (not Gear 300)
 

Hello guys

been trying a search about it but seems like everyone uses gear 300 but i have not found much info regarding Motylgear 75W90 as its Gl4/5 but not sure if its fine for our aisin gearbox?? As in australia its quite hard for me to source the gear 300 i only found Motylgear 75W90 stuff but not sure if this is a slightly inferior product or compared the gear 300 its alot worse. Im trying to flush the gearbox sitting at 3900miles as its been hard to shift from down from 3rd to second (more like impossible without going to neutral then in) when it is cold everytime.

Any replies will be appreciated

Thanks!

Hey there! The Motul 300 75w90 is fine for our application. I have been on it for months and no issues! Only thing I could give you in terms of words of advice is that there are the motul 300 type LS and the regular motul 300. I was curious about the two and wondered if I could throw both in there and was told by Motul themselves that the LS should be for limited slip and the trans should take only the regular motul 300. Hope this helps! In terms of your shifting issue, try out the motec shift springs. Those are supposed to help us shift much better with improved accuracy as to getting into gear.

I think if you read his post he says he can't find Motul 300 in Australia, and he was asking about Motylgear, NOT Motul 300. The Motec shift springs are actually stiffer than stock and will want to hold the shifter lined up with the 3-4 detents, and you actually need more pressure to pull the shifter back over and down to the 2nd gear location. At least that's the way it is with my Motec springs I have installed.

oh my bad!! well there goes that. hmm the springs helped me all over the board.

I had the same problem, could only find the gear 300 for $80 a liter (need 5 for gearbox and diff)

Ended up going with Redline MT90 and 75W90 for the gearbox and diff. I'd go for those as they are cheaper and much easier to find in Aus.

Guess ill probably have to go with something else then as well

Thanks for the replies!

If i can get this 2nd gear shifting issues im definitely interesting a motec shift spring though haha

I have the Motyl Gear in my FR-S right now.

A local shop has them in stock and their car runs it, so I gave it a try.
So far I have about 5400 miles on the fluid, and under normal driving, honestly I don't notice any difference. I guess that's a good thing.

At the track with OEM trans fluid, I had couple times where downshifting from 4th to 3rd required a good amount of force to get into gear while heel-toe'ing.
I've tracked the car 3 times now since Motul, and haven't had any issues.

Car has about 10,600 miles now.
