 Overdrive Light Burnt Out or Just Never Coming out of O/D?

Getting the Wheeling Fever

Hi all,
Having some issues with my automatic transmission on my '85 4Runner. I'm pretty sure that the truck is in overdrive no matter what I do with the switch, but before I go any further, I want to see why my O/D Off light is never lighting up.
I took off the panel and poked around, but I wanted to know if someone here has ever replaced a burnt out O/D off light.
Once that's fixed, I want to see why my O/D never turns off.
I'm guessing this could be a solenoid issue?
Or a loose connection between the switch on the stick and the ECU?
Any thoughts on both issues?
Peace,
Justin

If the solenoid were bad it wouldn't go in to OD. You can't tell by the RPMs if you're in OD or not ? <img src="/forums/images/graemlins/rolleyes.gif" alt="" />

Yeah, I'm definitly going into overdrive. The RPM's around 45, 50, 55 (my speedometer is off from my 33's) are low and reflect a 1:1 ratio.
That brings me to the main reason I posted this. When I hit overdrive around 45 to 55, I cannot accelerate for the life of me (maybe 1 mph per 3 to 5 seconds of time). I have stock gears on my '85 with 33 x 10.5's, which would explain for some slow acceleration but there's a catch.
I recently had a full tune up (plugs, wires, rotor, cap, fuel filter, diff's flushed and filled, idle was definitly upped a little bit) and my acceleration at this speed (45+) was MUCH better before the tune up.
Forgive me for my lack of knowledge on engines and such, but, given those items were replaced, what could cause the slow down in acceleration?
Peace,
Justin

Sorry if this post is too late, but there are 2 bulbs behind the O/D indicator. The part # for anyone interested is 84999-10110. Up here the stealership wants $12.50 each for them, so mine are still burnt out.
Anyone know of another source for these bulbs?

OK, good before tune-up, slow after tuneup. Your answer is in there. Maybe the timing is off. A spark plug wire on wrong cylinder?

I'm assuming the timing is off. Because it runs very smoothly with no misses or hestiations. Its just the snail-like acceleration around 45 - 50. Thanks for the help, Justin
