    Switched overdrive off today while driving and noticed the O/D OFF light didn't appear on the cluster. Son-of-a. Any possible reason for this other than the bulb being burnt out? ...which is odd for the amount of use it gets.

    All the dash indicator bulbs are prone to failure, ie. "D", "pwr", etc.

    It could be the switch itself.

    I have to wiggle the switch slightly every now and then to get it out of o/d. The dash bulb would not come on and it did not downshift. After cycling the switch (off-on-off-on. . .) a few times and a little front to rear wiggle it now functions normally.

    if you are extra paranoid you can check if there is a stored tranny trouble code in the TCM. of course you need a working o/d light to do that :D
