Pneumatic clutch

Posted by ewrecks On 2017/8/29 23:17:21

There is a 49 Packard convertible currently listed on eBay that has a " pneumatic clutch- not working"
I remember riding ai a 49-50 Packard Sedan back during the Johnson administration that allowed the gears to be shifted....I think...without operation of the shift lever.
Might be failed memory, but I am sure someone will correct me if I am wrong.
I am just curious for some information about the pneumatic clutch, how it operates and how difficult it is to repair.
thanks
