70 road runner 440,727 torque flight,driving home after a 40 min cruise on a less then 300 mile tranny rebuild,goosed it to pass an older gentleman who decided to stop in the middle of road,at the point i heard a loud whinning sound from tranny,sounded like a fan belt,got home,noticed at speed and not accelerating noise gone,but got terrible again at the stop light.Got home,let it cool,fluid perfect,no burnet smell,and full.Start it up all normall,until i put in drive or reverse with foot on brake,back to park or neutral no whinning sound,any thoughts where to begin? or do i need to pull the tranny after only 300 miles,any direction would be appreciated,thank you,

Make sure it has enough fluid hot and idling in Neutral. look for foam or air in the fluid. check your flex plate bolts may have lossened off?

Rather than pulling the tranny which would mean taking it apart blind take the car to a tranny shop & have them drive the car... As mentioned it could be fliud bypassing the pressure regulator causing a resonating buzz/whine... It could be the front pump or it could be the convertor... A guy that has done trannies for a living should be able to pinpoint the noise & & if it's the pressure regulator the trans stays in the car....

Quote:
Whining when loaded in gear is usually caused by pump restriction, such as clogged filter, or by a bad torque converter.
and bad cheap converters usually fill the pan full of junk!
course could be a malfuntioning valve body to??
