Synchromesh v. Redline MT-90 (and YES I DID SEARCH!!!!)

[87Camry5Speed]

After watching the miracles that GM Synchromesh performed for the gearbox in my old gen2, I am looking to use the same product in my gen3.5- gears are grinding on occasion (and randomly), and 1-2 and 2-3 shifts are becoming very hard as the weather turns cold.

However, as I ran a search on this stuff, I learned that newer transmissions may be better suited to running Redline MT-90 as opposed to the synchromesh, and that whether the tranny took gear oil originally vs. ATF came up several times as a point of debate. Well, I do know my '95 took 75W-90 gear oil when I changed it last summer (mixed in 1 qt of ATF to try to smooth things out a little more), and it seems as though the gear oil faction tends to lean to the MT-90. The Dexron III guys (my former gen2 comrades) loved the Synchromesh (I started a thread singing its praises back in the day)

So, in cliffnotes, what I'm trying to ask is whether you would go with MT90 or Synchromesh in my situation. And one more thing- when I did the refill last summer, I stripped the refill plug beyond salvageability, so it's basically frozen on there- we refilled the trans through a conduit on top, and honestly I don't even remember which one except that there was a roller bearing in the end of it- do I have any way of getting the plug off at this point? It's not rusted, just very very tight, and very very stripped!

The general idea seems to be to use GM stuff in a worn trans with some problems, and the redline in a new or rebuilt trans.

Yea I think I'll use Synchromesh again then, damn car didn't want to go into Second this morning

Thanks for clearing that up swegyptian and for being the only person out of the nearly 60 who saw this thread to reply.

I run Redline MT-90 in mine, it greatly improved shifting in colder weather. GM Synchromesh is really too thin for your tranny, I'd try the Redline stuff 1st...

HTH -

I run Redline Mt-90 in every tranny I can that will use it. It's a godsend, in a months time, totally cleaned up the shifts on my Supra. Never used it in the camry, so I don't know about the tranny there, but in the Supra, The Stuff is Solid Gold in my book.

Hey dudes thanks for the input, I was lookin at Redline's site a little while ago and I am going to research MT90 and MTL (another lube but meant more for ATF- taking manual transmissions than gear oil-taking boxes). They're even a couple bucks cheaper than Synchromesh, an advantage that will be erased by whatever shipping comes out to be, but it's worth a look...

Update-- just ordered 3 quarts of MT-90 through 247-parts.com

Will update when I get the stuff in the trans and have it out on a few cold mornings... I'll post in the vendor forum as well

Got the MT-90 today, ordered through 247-parts.com... It's going in the crashbox (oops, transmission) this weekend so I'll let y'all know how it works. Seems to me to be very promising.
