Whine noise dealer says rebuild tranny

2010 wrangler unlimited 70k miles automatic. Whine noise in the engine bay seems to to be when changing gears. Is much louder when accelerating and turning. Dealer says transmission fluid is burnt. There is no change in performance. Shifting is smooth. Out of warranty. They say rebuild for $2100. Is that what I should do? Or try to replace fluid and see if that works?

I would get a second opinion from a reputable private trans. shop. A number of dealers use private shops for their trans. work anyway so why not get a second opinion.

The #1 killer of auto trannys is heat, burned fluid indicates it got way hotter than it should have. Take it to a shop that deals with transmissions only, and they will tell you pretty quickly what the problem is. When my 7.3's transmission went, I had no codes. They hooked it up to a computer and saw things that I couldnt.

If you suspect you have a tranny issue, continuing to drive it just increases the repair bill.

Try changing the fluid (complete flush) and filter. Add an auxiliary teams cooler. If the fluid is burnt the trans overheated. 3.8s have woefully inadequate trans cooling, adding a supplemental cooler is a 100% fix. It may not be too late to save your transmission.

Two other opinions today confirm that the transmission needs rebuilt. Not going with the dealer who is $500-600 more than the other two estimates.

I would do this. If the trans is working fine otherwise then do the above and drive it with the realization that a trans rebuild may be in your future. Most trans shops I have dealt with will tell you that you need a rebuild no matter what your issue because that is how they make their money. I had a Chevy Blazer that needed a new valve body in the trans. It was a known issue and 4 shops told me I needed a complete rebuild. I ordered a valve body, put it in myself and put another 75,000 km on it before I sold it to a buddy who is still driving it. I saved about 2 grand. It's your money.

I agree. At this point, you really have nothing to loose by doing this. A trans. fluid/filter change is inexpensive. If that doesn't seem to take care of it, you'll have to do the rebuild anyway.

You'll need to do a full change, perhaps a flush with filter change. If the trans needs to be rebuilt after that they can recover the fluid. I agree with grizzstang and kik, if the clutches are working ok then change that oil.
