Has anyone ever put a auxiliary trans in their 1st gen? Like a brownie box or Spicer...same thing I guess. I am curious about a under/direct/over drive unit. Shifting more doent bother me because Im hardly in a hurry and drive a semi for work. But more control of RPM not dealing with gap between 3rd and 4th in getrag would be nice. I swear every road has to be 35mph.
