She bought the car used from a dealership. The automatic transmission worked fine up until she had the fluid changed in it. Then the overdrive into 4th gear just stopped working. I am pretty mechanical. Is the overdrive on an automatic Hyndai a simple fix or what ? I have read thats its an electric engagment and might not be to hard to fix. Has anyone out there worked on this type of problem ?
Thanks,
Cystoman

Crystoman - I know your post was over a month ago, but I'll bet I know what happened. I'll wager anything that the shop used the wrong ATF. In a Hyundai automatic, you MUST use SPIII ATF. This is available at Hyundai or Kia Parts Departments, or also at Mitsubishi Parts Departments, as the transmission was originally a Mitsubishi design.
 
Interestingly, our large Hyundai dealer here uses a synthetic base "so called" equivalent to SPIII ATF. I don't know how they can get away with this, as Hyundai corporate specifically states to use SPIII ATF. And, it also states as such as in the Owner's Manual.
 
You can go into any auto parts store, such as Advance Auto Parts, Autozone, etc., and you may find ATF that "claims" to be an equivalent to SPIII ATF. Don't use it, because it's not. Simply stated, if you use anything other than SPIII ATF, the automatic transmission will not work as designed, and its use will cause the transmission to fail.
 
Same goes with any of the Quick Lube stations, NONE of them stock or use SPIII ATF, and don't let them tell you otherwise.
 
Again, you must use Hyundai/Kia/Mitsubishi SPIII ATF in the transmission. Yes, it's more expensive than other ATF, but you will be rewarded in the long run by a reliable transmission.

Better late than never - youre neice has what we in the industry refer to as a hook and stitch. - if you take apart your shift handle I bet you youll find that the wires from the overdrive switch in the shift handle down to the junction connector are broken - I had the same problem with my car, and this is one of those things they love to get you on, they charge you 1500$ say their replacing the trans, and they fix two wires. your overdrive is coming on and off because of whats left of the wires flexing back and fourth.. eventually itl be gone all together... - try this I bet you that fixes the car..
 
Also, despite what anyone may tell you the hyundai certified transmission fluid is nothing different than the stuff you buy at the autoparts store, all youre paying for is piece of mind, I've seen the production charts of these chemicals and they use the same exact detergents! I've fixed this problem before, it happens due to cheap wiring in the shift handle... - to have a gear be there and suddenly not be there is unheard of, if it had anything fluid related to do with it youd feel loss of oil pressure in other gears, not just 4th..

I beg to differ, Ben. I've replaced quite a few transmissions which had "recently" been serviced with Dexron/Mercon ATF instead of SPIII. The one thing they all had in common is that the customer paid for the new transmission, which if had been filled with the correct fluid, would've been covered by warranty.

what do you work at a dealership or something? I dont get why everyone is trying to upsell the dealership fluid... no transmission fluid is any different than any other transmission fluid.. yes there are tranny fluids for gm and for ford, and chrysler and honda, but ive seen shops put this in cars... keep in mind these cars are junk to begin with.... their throwaways, did you actually take the trans apart inside to see what failed on it? im a trans tech, I dont just replace transmissions, I fix them. if you had an actual evidence of damage in the transmission I might believe you, but dealership warranties are shit to begin with.. I fix all the cars you guys "dont cover under warranty" if these fluids are truly different, Id like some evidence.. send me a copy of an MSDS with the contents of SP3, because until there is evidence, the difference between SP3 and dex merc remains unknown, which doesn't prove either one of us right or wrong... however, in my experience, there isn't any problem using the dex merc fluids on transmissions... just look at what goes into manuals, you can use ATF, diffy fluid, anything you want that is oil, more or less.. its designed to lubricate, and ATF is an ultra thin lubricant, it lubricates everything.. the only differences per GM and ford are the weights of the oil...

#15 of 49 Hyundai Accent ' '03 - Automatic Transmission Issues by pb84

Hi,
 
My hyundai accent's automatic transmission has the following issueS:
 
A. When I start the car, it wont pick up easily, it takes a lot of acceleration (feels like i might be picking it up in the second gear), high RPM etc.
 
B. When I go past say 70 or 80 KM/HR, the engine makes a lot of noise like its struggling, and the RPM goes above 4000, which never happens!!
 
These two things happen most of the time now, although, on some occasions the car runs smoothly, but will start acting up on the trip back, or during the trip. Sometimes it even starts running normally AFTER Ive run it for sometimes.
 
Please help!
 
P.

Can you feel it shift at all? If not, it may be in "default mode"--essentially stuck in 2nd gear--which would indicate a problem with the computer.

Yes, It shifts. Problem occurs when i pick up initially, or when I go over 80. Feels like its stuck, engine makes a lot of noise and RPM goes up.
 
Thanks,

#18 of 49 Can't go in reverse unless its cold out by funkymonkeyy

It also shifts hard into 3rd and shifts hard going down to 1 it is an automatic. Interesting enough it shifts fine into any gear when its cold out around freezing temps. Anyone have any ideas?

Is your DTC p0723 (2 to 3rd gear ratio, off top of my head)? If so try the speed sensor, it is about $50US else it is rebuild time is my guess. This what happen to mine. Note the advice is free for what that is worth. On 2nd try with junkyard trannies. Like the guy said they are throw away cars and I have read where rebuilts only last a year ($700us) but there is a place in San Berdo.. (around pick a part) which will give a 3 year for $1800 you install it. But the car does get 45mi/gall, best. I got 150K miles on the tranny and used dextron in the last 30K. I think that is what kill it plus a cartop carrier and moving wood panels. Stick with the factory oil or atf 3, chrysler since it is their tranny.
