Have you ever read why it's called "remote"? I'm curious because the shifter is directly on top of the trans, just like the NP435, the T18/19, the Mazdog M5OD-R1/2, and the ZF S5-42/47.
I guess I can see some similarities between that TOD (despite the errors I just noticed in that diagram) & the SROD, now that I really look for them...
And do you know what "RUG" stands for (if anything)?
