Hi Everyone, long time no post!
I have a 1951 DeSoto Custom (S15) with a 250.5 L6 and a two range Fluid drive transmission.
Currently the issue I'm having is that when driving the car, when its cold there are no problems, but as it heats up I start to notice a squeaking coming out of what sounds to be the transmission.
This only happens when I am driving along after the car has shifted out of underdrive and I am not accelerating any more. I notice a squeaking that is speed dependent (faster if I'm driving faster) when I let off the gas to coast along.
Any thoughts on what this might be?
