Transmission, gear, whine
I have a problem that has just occurred. I have a 1994 Jeep Wrangler, 4 cyl, 5 speed. It has 112,000 miles. This past week, a "whining" sound has occurred in all of the gears. It only begins when you push on the accelerator after shifting into each of the gears.
If you release the accelerator the noise stops. If you put on the clutch the noise stops. If you coast, the noise stops. If you press on the accelerator, the noise begins again.
The noise increases in frequency, with each gear change. It is almost unbearable in the cab, yet when you reach ~55 mph, the frequency drops.
This whining noise can also be heard as the jeep passes by. I had my daughter drive it past me so I could hear.
Does anyone have a clue as to what is causing this noise with the gears. I would think you would hear it at all times, whether one pressed on the acelerator or not. At first I thought it was tire whining, like the high pitched whine that one hears from a semi-truck. But it looks like it is more complex than that.
Any suggestions, comments, are greatly appreciated.
