Whiny noise

2000XJ, 112k, 4.0 auto. So it's very cold here in NY, 12 degrees, so not sure if it's a weather thing. When I started this morning, the engine had a whiny sound to it. Same when the car was driving, the sound followed along with the shifting sounds of engine/transmission. I have been changing the transmission fluid slowly but I don't think that's causing it. It seemed to get better as it warmed up. Also, when I stopped at a hill and had to accelerate from a dead stop, it seemed to slip or hop out of the stop. I'm not sure if that's connected, thanks as always for the help.

What type of transmission fluid are you using ?

A recent Gallup public opinion poll shows the NRA, at 58% approval, has a higher approval rating than either Hillary Clinton or Barack Obama.

Dex/merc. I've drained and filled 2x now over the last few hundred miles. I've only had the truck for about 6 months now and I've come to learn how neglected it was. The fluid looked like it was never changed. It was shifting fine and all but I wanted to slowly change it out. I'm hoping this is just an odd sound from it being cold outside but very odd.

The most typical part to make a whiney sound is the power steering pump. Keep an eye on all fluid levels and listen for any changes in the noise.

Good point. And, it's never a bad idea to change the power steering fluid either.

If you own a Renix Jeep, you'll want to check this out.

mine makes that noise when turning at low speeds, and on the very cold mornings we have been having, -15 with -40 wind chills the past few nights, i have noticed that when its that cold it may be a good idea to set the parking brake and shift to neutral to allow the trans to warm up before taking off, i mean we start the car to warm up the oil why not the trans?

but anyway that cold and giving it gas the trans likes to whining noise to it (its topped off and in fine working condition) after a few minutes its warmed up and good to go

Thanks Cruiser, Tim, and Um. It may be from it being so cold. I'll try changing out the pump fluid too.

Even if you remove the fluid from the pump with a turkey baster and then top it off, that may help. Then, do it again in a week or so.

Could be any of the belt driven items, I had a minor whine for a few years, then my alternator died Monday. New alternator and no more whine!
