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.
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.
