2000 Dodge Ram

Transmission problem
2000 Dodge Ram V8 Four Wheel Drive Automatic 94,000 miles

My truck runs great, but when your going about 45 MPH down the road and give it a little gas it makes a noise like a starter engaging when the engine is running and goes away when you let off the gas or floor it. Anyone have any ideas?

That is an interesting one. Have you checked fluids in the differentials and the transfer case? I also need to know if you checked for play at the ends of the driveshaft where the yokes go into the differential and transfer case for play. Finally, does the sound go away if you are using 4wd?
