[TR] Experience with Vitesse 5-speed transmission conversion?

[Anthony Rhodes]

Hmmm. 3K rpm at 60 MPH is about what my 4th gear is on my non-OD tranny.    I would have thought that the Miata 5th gear might have been “direct”, like the TR’s 4th. And 6th would be some sort of overdrive. 

Without having 20-30% overdrive then there is no great advantage to the Miata unit!
