Alright, well I have recently purchased a 2000 Hyundai Accent, 1.5l SOHC, automatic. 117k miles. The problem is, it won't shift into overdrive. It appears that the overdrive button works, as the dashboard light turns on and off, but pressing the button has no effect on the transmission, as it still doesn't go into 4th gear. It's 3rd gear all the way down the freeway, which really limits me to cruising at like 60 mph. Any ideas what this could be? The fluid seems alright, and there's enough I believe.

Well the O/D button does this.

If it's on as in no light on the dash on,

You will be in third gear unless u depress the gas hard in order to pass or get out of danger it will drop 1 gear and shift to O/D.

If you turn OD off, where light on dash is on

it will shift through all your gears normally.

No, that's the problem. When the light is off, it still doesn't go into OD.

Dear vanfullofmidgets,

You must be getting a Check Engine Light on your dashboard. I say this because the troubleshooting chart for your Accent's transmission lists a long list of codes and the cause. Per the flow diagram, it is almost impossible for your Overdrive to not work properly and not give you an CEL code.

That code would really help the Forum out to diagnose your problem. Can you go to Autozone and get your CEL code read for free?

No, there is no CEL. I have been looking through Hyundai's service manuals and haven't really found much.

Now I'm not new to cars, my previous VW Rabbit lasted 575,000 miles until it finally blew a headgasket. I am in college, so I had to have something cheap and this thing was the only option. (I see why it was cheap now...)

The transmission seems to shift fine, and you wouldn't notice a single problem with the car until you get on the freeway and the rpm-s go up to 4k when you're going fairly slow. I am leaning toward this being an electrical problem, however, I'm not positive. Fluid is good, and looks fairly new, actually.

Oh, and gbajosh, I think you're confused a bit. "OD Off" would mean that it WON'T shift into 4th gear.

Yeah I was just misinformed by HYUNDAI. which is what usually happens.

Hyundai told me OD off meant the OverDrive feature (not gear) is off.

as in stepping down hard to drop a gear and go up one to pass a car won't happen.


But it really is that if OD off is lit up you only use 3 gears.


Hyundai trannys are aweful. They will go before the engine does, which doesnt say much.

I hate this thing, honestly. I realize this is a Hyundai forum, but this car is apparently junk. 117 thousand miles, and the transmission is already losing gears? I wanted to be suprised, but apparently I won't be. My Volkswagen, which was 11 years older, had an automatic transmission that worked (and still does) after 575 thousand miles. And it had only 3 gears too, but at least it was DESIGNED to have 3 gears.

Too bad.

edit: I guess it's almost impossible for it to not work and not have a CEL, but i took it to Autozone anyways, even without the CEL on (which works, because it comes on with the rest of the lights when the car is turned on) and no codes.

Yes, Hyundai's are awful. That's all it comes down to. When I first came here I thought there was something I was missing.

Then I see everyone just has problems. Many forums have good stuff, like hey look at this this is coool! but here its why does this do this? Or in your case NOT SHIFT GEARS!

I have an 89 celica that just OWNS.... and an 02 Accent that sux

:{

i feel your pain

Try replacing the transmission sensor/cable it is $35. I have to do this every 10Kmiles since the 100K mark. Everyone says it is the transmission but it is just the sensor/cable. It is a good car, just learn how to work on cars and you can make them last forever. Also get a ODC reader from Harbor Freight or Pep Boys when on sale and get familar with the www.hmaservice.com online manual.

It is possible and common for the od light to work but the module never recieves the signal. the problem is in the OD switch that is in the shifter. There are 3 wires that come out of the switch and run to a conector on the side of the shift assy. If you pull slightly on the red/orange wire it will pull loose. the wire breaks inside the insulation. follow the wires to the conector and jump the red/orange to the red/blue. drive it and see if your od works. if so rplace the switch. Good luck

My 02 did that for one day, on the way to work and back (70 miles total). The next day it was fine, so I guess that dosnt help you out... but I guessed it was something electrical cause the inside of my car got soaked in a bad rainstorm with the windows down all night.

Ever since (the rain) it does funny things once in a while.
The backlit radio screen is always on,
the dash turn indicator lights dont flash very brightly sometimes,
spedo/pod lights flicker ocasionally,
headlights flicker ocasionally,
It had 2" on the floorboards, I bailed the H2O out and drove home that night.

But also when the tranny did that it was the day after a friend borrowed the car so I figured he did a brakestand or something dumb and messed something up. But all was fine the next day.

Mine has about 65,000 miles
Yes these cars are fragile and junk lol.

Tech1 was right> I just fixed the same problem on my 1997 accent. I took apart the covers to the shifter to get at the wires comming from the overdrive switch and there was a broken wire. After splicing the wire the overdrive worked again. I was having the same problem as you with the light on the dash working but no overdrive.Thanks again to tech1 for his advice.

I was having the same problem only the light on the dash did not work. The car would not shift into overdrive. Two of the 3 wires from the overdrive switch were broken. The wires were tightly bundled and zip tied and it broke at the fold inside the cover. I reconnected the broken wires and overdrive works and the light on the dash also works now. Easy fix...just remove center console to get to the wires.

Hi there,

It seems that I have the same problem with Elantra 99. Anybody can tell me how to check those wires? Is it the gear-stick shifter that you guys mentioned about? Are those wires inside the gear-stick, and then I have to open it? Thanks a buch.

D.

When my 2000 did this it was the start of the end to my trans..I ended up swapping out 2000 trans and put in a 05 trans.My 00 trans had 100000 miles on it.
