Ahh, thanks for the fuller explanation. I had no idea how the synchros
worked.

The zinc content of motor oils has been drastically reduced since 1994 to
help prevent damage to emission control devices. That zinc (along with
other additives) is what helps protect the gears, synchros, etc from undue
friction.

Honda MTL (Manual Transmission Lubricant) has all the additives your
transmission needs, since there is no concern for emission control devices.

It's all I use. And I change it every year, with the mileage I put on.

hows it look when you drain it? just curious. i imagine it would be
about the same color, possibly with some very very fine metal "dust" in
it. or not?

Mine looks pretty much the same colour as it went in.
Most (all?) Honda trans have a magnet stashed in them from the factory (yes,
even the manuals), and I've added a magnetic drain plug.

The big issue in changing type of fluid is that a different formula is
used for seal swelling and synthetics tend to leak past old seals.
Other than that, I am a big fan of Redline and use it in several vehicles...

Ahh, thanks. That's the info I needed.

You're right, I missed "Re: Clutches & Braking", 11/29 @ 4:37 p.m. Thanks.
