I have a 1951 DeSoto Custom, fluid drive.
A couple of things:
I have to use the clutch to shift from 3rd to 4th. Car downshifts at a stop sign normally.
If I don't use the clutch when it is supposed to shift by lifting on the gas pedal it makes a tremendous grinding noise as if the transmission would
just fall out the bottom of the car. Once in 4th it will occasionally slip out of gear so if I Iet up on the gas it goes back in gear and is fine.
Also,
At times it is very difficult to back up. I have to really give it the gas in order to move. I don't think this problem is the emergency brake but
it could be I suppose.
I've owner the car for 30 years and nothing has changed.
