Fresh 22k mile MV5 transmission going in. One of the few times I can say something cost less than the Miata equivalent.
Went to drill and tap the case for the temperature sensor and turns out that unlike the MV7, the MV5 has a temp sensor just below the fill port, very similar to the place I added a sensor on the MV7. One 1/2″ to 1/8″ NPT adapter and the sensor’s mounted.
Need a different driveshaft/adapter and different crossmember to fit the MV5. I have all that here.
The reason for the change to MV5 is simply availability and cost. MV5s are everywhere. So long as I’m on a factory junkyard trans I’d like it to not be unobtanium, in the event that I need to find one quick. Also, I can have one in the car plus a spare on hand for the same price as one MV7.
