What manual trans fluid to use?

[Guinnessmike]

I have read several posts about what manual transmission fluid to run, but most are for later model and/or AWD transmissions and there does not seem to be much agreement so I thought I would try to get a clearer answer that applies to my specific issue. Since I bought my 93' Talon ES, 100K miles (FWD manual trans) it almost always grinds when putting it into 1st gear unless I shift real slow or from 2nd gear, and it sometimes grinds a bit going into 3rd. My 1st thought was to try changing trans fluid but I do not have an owners manual so I do not know the correct oil to use and if there is one out there that will work better to stop the grinding. The general consensus is that I need 2.5 qts. of 75W-90, but of what manufacturer and is that the best grade? A lot of guys on the other posts say Royal Purple is the best...or it is terrible, AMSoil is great…by not recommending...etc. Can anyone set me straight?

witch of these products do auto zone, O'Reillys carry?? autozone said they dont carry redline... do i need to add an additive to the trans or not??

I use a 60/40 mixture of penzoil syncromesh and redline heavy shockproof

I go royal purple all the way... but I think some of the hype is just opinionated

The guy at napa told me to use gear oil for a 1992 eclipse 2.0 fwd. So i purchased napa premium gear oil is this correct? i don't see any viscosity ratings its a very thick yellowish oil. I have not put this is yet as im in the process of replacing my clutch....

Wow lots of good information in here that may be relevant to a problem I've been having. Think I'll change my tranny fluid soon. Good thread.

Redline MT90 mixed with Redline MTL

Amen.

It made a night and day difference when I switched from the Autozone special to a Redline Mix.

The Mitsubishi fluid is like $90 for a gallon?
No thanks.
