Greetings, I read your question and I think Reliable-Store can help you in this. Here's the site link.

it may be from failing engine mounts allowing the engine to misalign the drive shaft under acceleration and allowing problems in the cv joints or "U" joint

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.

my 4k cant go to 2nd gear even you do adjustments.what is the problem?

This transmission is electronically shifted via solenoids controlled by a computer, so you need to have that tested for fault codes that may be in memory.

This button only makes the gearbox change from 3rd to 4th or 4th to 3rd, will not down shift in any other gear, make sure it is in 4th gear, usually above 60km, than press o/d off it should go into 3rd gear, if it does not than see a automatic specialist, it is usually a sensor, if you go to Toyota they will charge you a fair bit.

Check the operation/adjustment of the 5th/Rev gear gate and associated selection levers.
Check 5/R gear lever linkages are operating correctly.

hi fro uk this is a common problem on many cars not just hyundai and ita most common cause of synchro mesh failure on2nd and 3rd gear is believe or not a bad driving habit! it goes like this when you set off in 1st then cange up 2nd gear whilst accellerating holding gearstick? in back position then change up 3rd gear still holding gearstick! in a forward position then? when up to 4th gear we let go of gearstick?? now just by holding g/stick whilst in 2nd and 3rd the slightest pressure also brings the synchro ring into play whilst gear already selected! so inevitably the synchro ring wears away to extent that they no longer work properly so the gearbox is none synchromesh on 2nd 3rd gears and on occasions? on 5 speed box 4th gear can become a victim ? hope you understand ? just quietly observe some peoples habits with manual boxes? as for repairs?cost? this is not a difficult job to replace all synchro rings but box has to be stripped and assesed ? the cost could escalate? but if you want quick turnround? a matter of hours? a recon box with warranty? is other option ? BUT would not advise risking a 2nd hand box probably worse or same as ? whichever choice you take you can check clutch at same time if milage is high? now some good advice! personally this is not a dire problem just a niggleproblem which if you take time in changing gears you can o/come gritty gear change save money for now till it is more affordable ? if you know any old timers truck drivers ? these are the guys who will show you how to drive /change gears none synchro mesh before it was ever invented ? hope this helps daughter but practice on gears and rid of the bad driving habit so many do not realise they have will make her a better experienced!driver
