Hi, I have a 2000 Accent with about 170,000 on it. A few years ago the OD button got “stuck” in the “on” position, so it won’t go into fourth gear. It’s an automatic tranny. I’ve been babying it by keeping rpm’s low and changing to Pennzoil. I suspect the problem is a broken wire somewhere in the shifter. (I checked and it’s not at the top, where the actual OD button is). My question is, would it be worth while to take the gear shifter apart to see if I can find the trouble, or just keep driving it the way it is? It’s our “second” car, I just take it to the hardware store and so forth now and then. I keep it off the turnpike, and try to keep the speed around 45, so as not to strain the engine. But I wouldn’t mind having all four gears again. I should also say, it has never had any tranny service, not even an oil change, unless you count the time the pan rusted out, and Mighty Putty wouldn’t fix it, and I took it to AAMCO and they told me that at this point, it’s best to just replace the oil that it leaked. Which actually impressed me, I thought for sure they would try to sell me a big tyranny job, but they didn’t.
Thanks, Mike in Maine
