    Default Auto trans grinding/loss of power when making sharp turns....

    '05 Rubicon w/ 42RLE auto trans and 70k miles.
    Transmission was serviced maybe 15k miles ago.

    This has happened twice now in the past 2 weeks. Both times has been after the jeep has been driven at highway speeds for around 15 miles. I go to make a u turn, get a metal on metal scraping noise (that's related to rpms), and loss of acceleration.

    Suggestions?

    Sounds more like T-case, or maybe front axle joints.

    Grinding shouldn't be from the tranny, if it's only during turning, has to be something that binds when the wheels are turned.

    There's a definite loss of fwd movement though.... the rpms move up, the jeep barely rolls fwd. So front axle is out of the question.

    I haven't thought about the t-case, but what would cause the t-case to grind/slip while in a sharp turn?
    I'll have to check fluids this weekend, unless it's been a very very slow leak, I doubt the level is an issue.

    I dont know about the grinding but the loss of power in a turn with an auto sounds like low fluid lvl, partially clogged filter or the filter pick up is not seated/cracked/damaged

    Not necassarily. The front axle and driveshaft are turning when the vehicle is moving (not powered in 2WD, but still turning)

    If there is something binding in the front end, it can slow/stop the Jeep even when giving it gas.

    Easy to rule out the front end for sure. Jack it up, and spin the tires, with the wheels stright, then turned left, then right.

    Chances are it's in the tranny or T-case, but the front axle could be the culprit.

    Could also be the rear diff. If it's not 'differentiating' like it should, and binding locking up on a turn??

    Does your jeep have "ESP"?
    If the computer feels like the Jeep is going to roll over when you turn, It will automatically hit the brakes to correct the roll-over.
    There is a way to disconnect it.

    The fluid was a bit low, so I topped it off and am waiting to see if it happens again.
