We recently put in a rebuilt transmission and torque converter. Since then, the transmission screams as if it may be trying to engage in 4-wheel drive as we are driving it down the road. This usually happens as we are ascending a grade. Once we reach the top of the grade and the pressure is released, the screaming starts. It stops once the engine has slowed to about 45mph and ends with a thud in the transmission area. It happens more often when there is a load on the truck. Other than this, the truck is running great mechanically and we are not experiencing loss of power. What could this possibly be?
