It is indeed pricey.  But it appears to be a complete new transmission and all the required adapter stuff ready to go.  The only way it would be better as a conversion is if it retained the original space cylinder. 

So for a complete new modern (hopefully long life) overdrive transmission, the price is not terrible.

It is likely a better solution than the HVDA because those old Toyota transmissions may well be “used up”,not just “used”. And they are hard to find.  

For me, I found the right Toyota transmission to be as rare as ... as a friend of mine puts it...   as rare as rocking horse manure.   He may not actually have used the word “manure”. 

So I like this Miata option!

Does anyone know the gear ratios?  The Moss description does not indicate the ratios.

Not sure there is any real world TR experience yet, this is a very new deve=
lopment - only installed on the MG side so far from what I gather.

Here is the website to the UK manufacturer:
https://www.vitesse-ltd.com/

Here are the gear ratios they quote on one of their TR pages:

The Mazda MX-5 gearbox perfectly compliments a wide range of classic vehicl=
es, offering a great set of ratios that allow for near-optimal power usage.

Gear    Ratio - Mazda Transmission
1       3.136
2       1.888
3       1.330
4       1.000
5       0.814
