I remember the vacuum shift assist of those days, but the reversed polarity of the ignition you mentioned is one I hadn't heard of??? Would you explain that one please. Ken

Personally, I considered it to be a bit of a headache. It was difficult to shift the trans while the engine wasn't running, for example (try shifting from reverse to second so that you could get a push-start if you had a dead battery for instance). Like the switch that reversed the polarity of the ignition every time the starter pedal was depressed, this Chevy "innovation" wasn't thought of all that highly back in the day - and many were deep-sixed long ago. ...and... "The vacuum cylinder which provides the assist is located under the car on the driver side near the transmission. If present, there will be a hose that runs up to the intake manifold to supply the vacuum. Simply locate it and follow it to find the cylinder. Many Chevy's that were originally equipped with this vacuum shift assist as standard equipment through 1948 had it removed at some time in their lives, though. As the seals wore, got hard, or hoses cracked the system became troublesome at best. Many outfits (Sears Roebuck for example) marketed kits to convert Chevy's to a completely manual (non-assisted) shift linkage for only a couple of Dollars." =========================================================== -----Original Message----- From: old-chevy-truck@yahoogroups.com [mailto:old-chevy-tr...@yahoogroups.com] On Behalf Of K Ohlgren Sent: Monday, August 30, 2010 6:31 PM To: old-chevy-truck Subject: RE: [old-chevy-truck] Transmission kit for 1941 thru 48 Chevrolets all right, i'm in the dark here. what is the vacuum shift for?
