this is caused from piston to cyl wall clearance when engine warms up the pistons exspand and the noise is less. DON'T WORRY ABOUT IT

why won't a 2001 Impala shift into high after it warms up? All shift sensors have been replaced

The fluid could be low, or the pump could be weak and makes noise until it warms up the fluid. There is an additive available to help quiet the pump.

Wait until it warms up and melts
