Question about Hyundai Motor 2004 Accent

Open Question

2004 Accent Auto Gearbox

My Accent sometimes fails to get out of first gear, it also drops down from overdrive to third with no accelerator input, also when it jumps down into third it will only take off in second. This does not happen all the time and you could drive it for weeks without a problem.

I have had it into the Auto Electrician and he said the "Computer Data was frozen", also said "no T.P.S" and "no pulse generator"

SOURCE: when i shift into third the gears grind.. why?

sounds like the syncromesh has gone in the gearbox. If you dont want them to grind, you,ll have to double declutch. I f you cant do this, get a new gearbox.

Hi

Well two of the tranny codes ; P0734 and PO732 indicate gear 2,3,4 ratio incorrect. This can be caused by poor readings at the input and output speed sensors or pulse generators. The P1709 code is in reference to the kickdown servo switch.

Replacing the pulse generator set and TCM reprogramming( as per TSB) may solve your problem, otherwise you have a major component failure in the transmission unit. I would get some line pressures at the transmission checked first.

Sounds like the transmission is in fail safe mode, this happens when there is a transmission fault, you only have two gears 2nd and reverse.

Hope this helps - Steve

SOURCE: automatic transmission do not drive when vehicle

your problem is with the electronic module for the automatic trans, you need to replace or have it diagnose with the hi scan pro from the dealer and try to erase the error code.

If the overdrive on my 05 Pontiac aztec is out... does that mean the transmission is going out and it all needs to be replaced or is it something simpler?? Harder?? Is it worth fixing???


the over drive is controlled by a servo/solenoid that sometimes fails
It could be a TCM problem
It is not an indication of a failing transmission unless you have more indications you have not mentioned and if diagnosed by an accredited transmission shop should be fairly cheap to fix.
It is worth fixing

Can you turn on and off the overdrive on a 98 ram 1500


I have never known an overdrive that cannot be switched on or off at will or engaged or disengaged.

There are two definitions of overdrive and in the philosophy of some people the fifth gear is an overdrive.
The conventional manual gearbox, because the first motion shaft is locked to the third motion shaft in the top gear ratio, any supplemental ratio that has a ratio higher than 1:1 is considered an overdrive ratio.

The more traditional definition of an overdrive is a supplementary gearbox that can be incorporated into a normal manual gearbox to provide a single overdrive ratio for the purpose of quieter and more economical cruising.
The early overdrive was cable operated by a large chrome-plated dashboard-mounted handle. Later overdrives were hydraulic units that could be switched in or out by electricity, often by the means of a steering column-mounted switch or by a tiny switch incorporated into the gearknob.

A typical installation included an inhibitor switch mounted on the gearbox which prevented overdrive operation in the lower ratios when the benefits would be dubious.
Sometimes a lower than standard final drive ratio would be used and the overdrive ratios which typically could be selected whenever third or fourth gear was selected could be used together to produce something like a six speed close ratio gearbox which was hitherto unheard of when some of the rest of the world was still using "three on the tree" type three-speed gearboxes.

Most manufacturers had dispensed with overdrives by the end of the 1970's due to the weight and added expense, in favour of the now common five-speed gearbox, though Nissan incorporated an overdrive ratio into their automatic transmissions to compensate for torque converter slip when fuel costs began to rise disproportionately.

If you have an overdrive unit fitted to your car that doesn't work, I advise starting the diagnostic process by checking through the electric circuitry, wiring, switches and solenoid.

When to use overdrive


Use it for relaxed cruising and better fuel consumption in top gear. You can drop to third gear with the overdrive still engaged as the occasion demands. Obviously, for maximum acceleration you need to disengage the overdrive.

Od light on


Hi there,

When you press in the Overdrive (OD) switch, this simply allows your gearbox to use the highest gear (when it needs to). For example, if your transmission has 1,2 & D gears, the OD acts as a 4th gear. This is useful on open roads and will help with economy.

If the OD light remains ON, then you have deactivated the 4th gear. This means the car will change up to 3rd gear only, until you depress the OD switch again.

Deactivating the OD is useful, when you wish to "manually" change down to 3rd gear, to climb a hill, or need better acceleration.

Shifting problems


never seen a dodge and autos a bit thin on the ground here in spain but i think the control you are looking for is on the side of the gearbox ,and if its like VW then its not cheap ,i repaired one by removing the offending item and drilling the rivits out then cleaning with acetone the paths on one side and rubbing a soft lead pencil on the brushes refitting a couple of nuts and bolts with instant gasket in the join and this car is still driving around a year later.
