All B-W "R-10" OD units made (since the mid 40s at least) are internally the same. Wiring varies with user. What makes it different from trans to trans is the roughly 1" thick adapter plate between the OD unit and rear of the trans. The solenoid mounts on the adapter. As far as I've been able to determine the splines on the input gear (female) on the OD unit is the same, the trans had a special short output shaft cut to mate with those splines. All the outputs are the same splines as well - at least as far as I've been able to determine from research. I know they are the same on AMC six cylinder transmissions, and that main internal parts from V-8 models will fit (there is no V-8 model according to my research -- all are the same). I've not had the opportunuity to mess with units used by other manufacturers, but the BW sources I've found say there was just one unit adapted to any size engine/transmission. I doubt a T-96 adapter will fit a T-14, but it might. Then there would the pr oblem of the trans output shaft though. --------------- Date: Thu, 14 Jun 2007 13:18:22 -0700 From: Tom Jennings <tomj@xxxxxxx> My newly-acquired '69 AMC TSM shows that the T96 and T14 received the same overdrive unit. I'm sure there's parts differences, but since T96 ODs are relatively common and unpopular, T14-ODs rare and (more) desirable, and plain T14's common, it sure sounds like a nice bench project.
