whining 400
my 400 started doing this at slow speeds mostly when just starting to move until it goes into 2nd. I was told there could be moisture absorbed into the fluid. I hust haven't changed it to see. I have it in my old 2wheeldrive suburban 454eng. I use to tow the FED with. I'm hoping that's what it is anyways. Hope it's not the pump or something to involved. I had that tranny gone thru 3trs, ago and have changed the fluid/filter once since then.
