Sounds like a plan. I will send you my number in a private email in case
you have lost it and we can knock this out one day soon.

My tranny is from the '96 model. I think that it is fully compatible
with your 1999 model, but we should make sure about that.
(anyone here know 100% for certain on this?)

This is the one that has 75,000 mostly gentle miles on it, working
perfectly when I took the car down a few years ago.
Regular redline fluid changes since 10,000 miles when I took possession
of it.

Another question, any idea what a "typical" charge is for a Miata
5-speed transmission rebuild?

Thanks!

Pat

Chuck, thanks for the addl thoughts. I can go in there and check this stuff
out and meanwhile, I'll not get too 'creative' with the fluid choice ;-)

Thanks again,
