    Default neutral safety switch

    Alright my jeep isn't shifting right. It slips in every gear but when I manually put it in first its normal, but only in first. It happened after I played in some mud. My dad did some researching while I was at work and we think it could be my neutral safety switch. We cant seem to find it. Anyone have opinions or pictures of where its located? I posted on Naxja but no one ever answers my questions there. Thanks!

    I'd be surprised if a NSS would cause it to slip. NSS keeps the motor from starting unless the transmission is in park or neutral.

    Keep checking back, more knowledgeable members will be throwing in ideas soon.

    maby this will help

    it is a part of the AW4 manual

    as i read when it starts to occur, i think it will be the shift linkage being out of adjustment.

    There is also a cable that runs from your throttle linkage to the transmission.
    From the FSM:

    THROTTLE VALVE CABLE
    Transmission throttle valve cable adjustment is
    extremely important to proper operation. This adjustment
    positions the throttle valve, which controls shift
    speed, quality, and part-throttle downshift sensitivity.
    If cable setting is too loose, early shifts and slippage
    between shifts may occur. If the setting is too
    tight, shifts may be delayed and part throttle downshifts
    may be very sensitive. Refer to the Adjustments
    section for the proper adjustment procedure


    Continued:

    TRANSMISSION THROTTLE VALVE CABLE
    ADJUSTMENT
    The transmission throttle valve is operated by a
    cam on the throttle lever. The throttle lever is operated
    by an adjustable cable (Fig. 180). The cable is
    attached to an arm mounted on the throttle lever
    shaft. A retaining clip at the engine-end of the cable
    is removed to provide for cable adjustment. The
    retaining clip is then installed back onto the throttle
    valve cable to lock in the adjustment.
    A correctly adjusted throttle valve cable will cause
    the throttle lever on the transmission to move simultaneously
    with the throttle body lever from the idle
    position. Proper adjustment will allow simultaneous
    movement without causing the transmission throttle
    lever to either move ahead of, or lag behind the lever
    on the throttle body.

    Checking Throttle Valve Cable Adjustment
    (1) Turn ignition key to OFF position.
    (2) Remove air cleaner.
    (3) Verify that lever on throttle body is at curb idle
    position. Then verify that transmission throttle lever
    (Fig. 181) is also at idle (fully forward) position.
    (4) Slide cable off attachment stud on throttle body
    lever.
    (5) Compare position of cable end to attachment
    stud on throttle body lever:
    Cable end and attachment stud should be
    aligned (or centered on one another) to within 1 mm
    (0.039 in.) in either direction.
    If cable end and attachment stud are misaligned
    (off center), cable will have to be adjusted as
    described in Throttle Valve Cable Adjustment procedure.
    (6) Reconnect cable end to attachment stud. Then
    with aid of a helper, observe movement of transmission
    throttle lever and lever on throttle body.
    If both levers move simultaneously from idle to
    half-throttle and back to idle position, adjustment is
    correct.
    If transmission throttle lever moves ahead of, or
    lags behind throttle body lever, cable adjustment will
    be necessary. Or, if throttle body lever prevents
    transmission lever from returning to closed position,
    cable adjustment will be necessary.
    Throttle Valve Cable Adjustment Procedure
    (1) Turn ignition switch to OFF position.
    (2) Remove air cleaner if necessary.
    (3) Disconnect cable end from attachment stud.
    Carefully slide cable off stud. Do not pry or pull
    cable off.
    (4) Verify that transmission throttle lever is in
    fully closed position. Then be sure lever on throttle
    body is at curb idle position.
    (5) Insert a small screwdriver under edge of
    retaining clip and remove retaining clip.
    (6) Center cable end on attachment stud to within
    1 mm (0.039 in.).
    NOTE: Be sure that as the cable is pulled forward
    and centered on the throttle lever stud, the cable
    housing moves smoothly with the cable. Due to the
    angle at which the cable housing enters the spring
    housing, the cable housing may bind slightly and
    create an incorrect adjustment.
    (7) Install retaining clip onto cable housing.
    (8) Check cable adjustment. Verify transmission
    throttle lever and lever on throttle body move simultaneously.


    Hope this helps

    its not the TV cable we already checked that. My alternator is bad and the voltage is really low. My dad moved my jeep and he said the tranny worked fine but the engine sputtered really bad. He thinks its not getting enough voltage.

    That might just be it. Not only does the computer need the voltage, but the electronic solenoids as well so they can make a proper shift. Get your battery charged up and then try it. 12V will be enough to work it right.

    Yeah I am kind of curious as to what it ends up being too... the last time I read about threads about people having issues with their Jeeps just cutting off and not wanting to start again... I kind of ignored the outcome.. until it happened to me, then I wished I had read them all the way through to the fix... Darn CPS!!!
