I have done quite abit of research on this - Getting ready to do this with a 2005 Miata 6-spd. Everything that I have read indicates that the
6-spd transmission was redesigned (or is a different design) than the 5-spd and should have less lubrication problems when towed. Have corresponded with a gentleman who has towed a 2004 5-spd for 9K miles and not had a problem. Aside from the "Mazda says No" is there any other experience or information on this subject that I did not find on miata.net, the miata mailing list, etc.TIA -
