[DML] Re: Eliminating Angle Drive

["Dave Swingle" <swingle@xxxx>]

It's a little more complicated than that. On the side of the trans 
(actually the differential housing) there is what appears to be a 
freeze plug. Immediately behind that is the back side of the ring 
gear (i.e. the side without teeth). It would be possible to put some 
kind of sensor in that hole, but the hairy part is that you'd have to 
put something to count (teeth, magnets, etc) on the ring gear 
carrier. There is nothing in place. 

This is very similar to electronic tach applications used in other 
cars, BMW for example uses a pickup on the diff housing to read the 
ring gear rotation. 

In the "other" application of the DMC Renault trans recall that the 
ring gear is flipped over. I suppose that there is something 
installed in that application to drive the speedo, but I've never 
taken apart a Fuego trans to see what. 

Honestly it would be easier to put a transducer on one of the inner 
CV joints (like many aftermarket cruise controls).
