What gear oil would you recommend for a 350k mile, 5 spd manual, 2wd Toyota transmission. Any additive? Transmission is ok, kinda noisy.

Not sure of an additive for it. Important thing is to get some new, fresh MTF in it. I know Honda manuals love AC Delco Friction Modified MTF to get rid of/prevent gear grind. Might get some of that. Honda has a TSB to use that on grinding transmissions. That seems to work better than even Redline MTF esp in cold temps.

Can't go wrong with Redline...Member OneEyePete uses it in his '84 Honda.

Hmmm...synthetic for something thats worn? I was thinking more 80/90 with some oatmeal mixed in. wink Then again, we do see -30 in the winter.

Liqui Moly ceratec is good to use in gear boxes as far as I know....just not in wet clutches like a auto. Should fill in a bit of the wear scares and such but who knows...I like it in my engine oil.

I have had best results from Redline MT-90 (75W-90) or Amsoil MTG 75W-90, both dedicated GL-4 manual transmission gear lubes. Toyota usually allows for a GL-5 gear lube as well in their manual trans units, but I have had better shifting from the Redline or Amsoil dedicated lubes. Kind of expensive for an old trans, but very smooth if that's what you are looking for.

Just trying to help it along. Engine is in the same condition. Runs like it came from the factory but it too has the same miles on it.
