Hello Jack, Here's the scoop on torque converter for C300. It is not the same as that uses on New Yorker and Imperial, but it is the same as that on the Windsor. It is slightly smaller and has slightly higher stall speed, but additionally it has fins welded to the outer case creating a fan for air cooling the transmission and the bell housing has more screened ventilation openings than the New Yorker and Imperial. New Yorker and Imperial transmissions are liquid cooled by a heat exchanger in the lower radiator hose. The Windsor transmissions are air cooled only. The C300 has both cooling systems sharing the New Yorker liquid heat exchanger and the Windsor torque converter (fan) and extra ventilation openings. Sorry, I don't know any rebuilders, but a good used Windsor converter should be available without too much searching. You could use a New Yorker converter, but the higher engine idle speed with your 300 could be slightly problematic and you would lose some air cooling effect which would not likely be a problem for you. I doubt you do a lot of high performance driving in your 65 year old car. --------Marshall Goodknight C300 air cooling only on my transmission.
