I had OD in second gear on my TR6 (with J-type) and eventually disconnected 
the switch.  It was a waste of time in my book.  At second gear speeds the OD 
takes so long to engage that you will be upshifting to third by the time it 
engages.  I suppose there are traffic situations where the speed will bounce 
between 10 and 40 MPH and having OD in second gear would be a nice thing to have 
but the TR6 has enough torque that third gear will work well, too.

The short answer is: Yes you can and it will work.  But my recommendation is 
it isn't worth the trouble.
