My S2000 has 18,600 miles on it now, I'm noticing that the gear changes are a bit more "notchy" than when newer. I'm wondering what is the expected lifespan of the Transmisson fluid. Has anyone replaced theirs with anything that might improve shift quality? If so, what do you recommend? I remember reading somewhere that some synthetics are too "slippery" and don't allow the synchros to spin up. This results in poorer shift quality. Any thoughts on that?

Chris,
So you know if there is a synthetic equivelent? I seem to recall using Redline MTL in the MR2. Could this work? I am glad to hear that it helped your shifting (though not the 1-2 issue).

It could be a synthetic for all we know. I would guess that Honda puts it out for bids with a spec and buys it from some oil company where the cheapest way for them to fulfill the contract would be to fill a Honda bottle with a standard product
.. but all that is speculation that does not answer your question.
Honda does not publish the spec or state an alternative or standard for the transmission lubricant. They do state that 30W motor oil can be used temporarily until Honda MTF is available so that gives an indication of the qualities needed.
Since it is not clearly stated most of us have used the Honda stuff. A couple of people have used Redline with no reports of great improvements or failures.

I have always used Amsoil in my vehicles, and I have found Amsoil equivelents for engine oil and diff, but not gearbox. I even called an Amsoil engineer in Wisconsin to see why only Honda MTF is acceptable, and he said Honda gearboxes require an additive that only OEM MTF contains. Unfortunately, this is a legitimate requirement, not just a marketing ploy on Honda's part.
