Re: 1940 overdrive?

G'day all, lots of good info here. I would like to add that the only advantage of an R6 is that it engages as a result of centrifugal action, no Governor involved. The only electrics involved are for kickdown. I would avoid the R6 unless you need one for an authentic 1939 ( Senior and Junior have different input shafts), as they can be damaged easily if not locked out correctly. If you have an R9 you are not out of the woods as they can be a bit recalcitrant and can also be damaged on lockout. R10 is Studebaker/Ford/whatever box and does not fit Packard and there are no interchangeable parts, apart from maybe the solenoid. R11 is a brilliant box and works well if you respect it. Read the instructions and try to understand how it functions. It is worth your efforts. I am currently fitting a 1939 R6 OD to my 1937 Super rumble seat coupe. No problems at this stage and I have sat in front of the vehicle for a few hours with the gearbox/tools and a beer. I have heard no thunderclaps or other indications that Mr Macauley would have disapproved. PT
