    Default Tranny issue..

    did a service on my tranny about 3 months ago but the problem just started..

    Fluid is foamy on the dipstick, doesn't have the burnt coloring or smell..

    what's its doing is hesitating between gears 2 and 3 (around 35-40 MPH)
    hesitation occurs when the Jeep has been running a while.

    the hesitation is so bad that the jeep lunges and sometimes it kills the Jeep... I'm at a loss.. can anyone point me in the right direction?
    thanks

    Default Just a shot in the dark...?

    Did you use silicone when you reattached the pan/gasket? Any chance that when you (if you did use it) tightened it down that some squished (technical term there!) out and into the inside? Even a small drop,chunk, or dallop can get sucked up into the innards of the tranny and block the flow through the passages. Just a guess...?

    used copper spray, then the gasket maybe I got some of the spray on the internals?

    Default hmm....

    Copper spray...less likely IMHO. Any chance the filter went on backwards/wrong direction...I know, silly but gotta ask. Also, have you checked the obvious stuff? Fluid level (flat surface, idling), any wires maybe get pulled off? This an AW4 or 999?

    Bubbles usually means too much ATF, Wrong type of ATF, or a plugged vent I think. With the shift probs, you may have clutch pack issues or a bad band, but I'm not a tranny guru by any means.

    tomorrow I'll check the lines and I'll drain some of the fluid out of it.. it's possible I overfilled it

    I agree it is the square headlights, as a founding member of "Real Jeeps Have Round Headlights" foundation I suggest doing a google search for the round headlight conversion kit and all your problems will be solved...

    after that I would check that you have the wrong type AT fluid or contamination causing the foaming. Sounds like one of the clutchpacks is not operating properly, either due to a lack of fluid or wrong fulid and it is slipping.

    There are two schools of thought on transmissions, change the fluid and and filter every 30,000 miles or never...I lean towards the first, however I am with 91Yeeper if it was high mileage and had never been changed I would have left it alone if you weren't having any problems...understand it is to late for that now
