Overdrive Throttle Switch = Frustration!!
Well, I think I've tried everything, so do I have a bad throttle switch? For the sake of full disclosure, this switch was replaced about 1,000 miles ago and worked fine until these latest symptoms appeared (old switch had gotten to the point where the contacts always stuck together and OD would not disengage. This new switch was installed and OD worked just fine... for a while).
What it's doing now (and, also for disclosure, I do have a test light currently installed):
With the car running:
- Driving along in top gear, flip the dash switch. Overdrive will engage but will dis-engage when the throttle is depressed more than half way. (I've adjusted the operating shaft on the throttle switch to where this won't happen, but then the OD will dis-engage while the gas pedal is not depressed - i.e. decelerating)
Now before anyone tells me about the 3/16 (5mm) adjustment detailed in the shop manual, please know that I've tried this, BUT...
While the car is not running (ignition on, 4th gear engaged), when I turn on the dash switch the indicator light will come on and I can hear the OD "click" in, but when I turn off the switch to make the adjustment the indicator light goes out WITHOUT depressing the accelerator AND the OD disengages.
Also, with the car off, ignition on, 4th gear engaged, OD switch in the on position, the light will come on but if I press and de-press the throttle, the light will go on and off accordingly (just like when the car is running).
So, do I have another bad throttle switch? Please know that I've adjusted this switch to all points in the range of where it will engage and won't engage. I know that I can bypass the switch, but I really don't want to. I just want to make sure I'm not overlooking something else before I replace this switch AGAIN.
While I truly believe that I got a bad replacement switch (typical, as of late, as it seems all re-manufactured parts I've been getting seem so cheap either of poor fit or not working or lasting), I'd love to get some of ya'll's feedback. Please know that I'll check back later, but right now I'm still pretty frustrated.
Thanks,
Devin
