Transmission weights

[lotsafords]

Does anyone happen to know the weights for the Early Bird Automatics, the 1961 Cruise o matic, the c-6 and the c-4.
Any help will be appreciated.

all the Borg-Warner transmission are quite heavy (FOM, COM, FMX) somewhere around 225-230 lbs plus 10-12 qts of fluid.  C6 is lighter and stronger at 140/150 lbs plus 12-14 qts of fluid.  The C4 is lightest at 110/120 lbs plus 10-12 qts.

Do you also know the weights of the newer o/d autos? Just wondering how they compare.

I would guess that a 4R70W would be slightly less with its pressed steel hubs (opposed to cast hubs) and fewer servos.
