I understand your situation Ryaz11 , you will not receive a new transmission because I doubt that there are any new transmissions available in Australia. It appears that Hy, send their transmissions to a 3rd party reconditioning specialist company who repair the transmissions to Hy specs, so a reconditioned unit would most likely not fail again.

However, due to the age of your car / trans, I would request that your specific trans be repaired and refitted into your vehicle. I'm not sure if this is possible, but I can't see why not.

Six months ago I had a trans failure in a non Hyundai car. without warning a control unit failed and the trans wouldn't shift out of low gear, fortunately I was close to home & had the car towed to a repair shop. Cost $400 to repair trans running beautifully. I mention this because although the symptoms seem severe, sometimes the fix is not as bad as it seems. I hope that is the case with your car too. Keep us posted.

This is all a little alarming.
My own UK CRDi auto (ie a 1.6 diesel with 4 speed torque converter auto, Czech built in about April 2010) has just had a new gearbox fitted @ about 18000 miles.  I understand that the gearbox fitted is new & not exchange etc.
Symptoms that led to this were different to those described above though - mine would not kick down from 4th to 3rd when driven at about 1500rpm /40-50 mph, would go to 2nd instead with a bang and often with an alarming judder and squeal.
Gearbox would change to 3rd OK manually though.
To me it seemed a shame to replace the whole unit when (I guess???) only a small part or control unit might have been at fault.  All is well again now though - so full marks to my dealer & to Hyundai UK for sorting under warranty.

Yes, that is good news that your dealership sorted the problem out. 

[Phil №❶]

Yes TH, may be a different situation in the UK than Oz, Your trans @ 18K miles was still considered "new" so a new one fitted. There is probably an arbitrary cut off where a recon unit is fitted. So glad your problem is fixed. Some of the valves that play up are worth about 20p but cost a lot to get to. I believe the units are strong enough to take the diesel torque when it comes to gears and shafts, I've never heard of anyone's trans actually breaking, which is good, but these control units & valves seem to be the weak point.

Hey Ryaz11 sorry to hear you are having trouble with your I30 but i would be fighting them for a new replacement transmission. I was told that a new one would possible take months to come in and as my car had more than what would be considered acceptable kms then i was only entitled to a reconditioned one.  I would consider yours still new....
 Mine had its 90000km service today and i once again was complaining about lag and slipping in the transmission when going up hills. I feel like its about to start down the same path but this time i am alot more aware of what my car is doing and not will to write it off as wear and tear. The service centre could not find fault with the replacement transmission and nothing was being reported by the cars computer and when they checked the oil it was not burnt (my nose must of imagined the burnt oil smell) but told me to monitor it and bring it in when it was playing up. They never did get back to me with the original report of what went wrong with my original transmission. They changed the transmission oil today and I am off on a 450km drive tomorrow so will see how it travels. A mechanic friend had suggested that there may have been debris in the recon transmission that may have been causing the current issues and flushing it may help.  we will see

The saga continues......

[Dazzler]

Hope all is well Mel 

[Mel]

I hope the saga doesnt continue db i just want to drive my baby and not have any issues and am saddened to see others that are having the same issues.. yeah things are ok dazzler life has been busy and i have been a stalker instead of a reporter but hopefully things are on the up and up so more time now and its a happy day when diesel is cheaper than the E10 petrol lol

[Dazzler]

I hope they get to the bottom of this bad batch of transmissions ...The earlier Autos appear to be rock solid

If a recon was fitted, does that mean you get a "bad batch" replacement 

[Mel]

probably as i was to understand that there would be a car driving around now with my old transmission that would now be reconditoned so the bad batch of transmissions are just going round and round ....  hopefully the guys that recondition them are really good mechanics that fix all problems that these transmissions seem to have

[Phil №❶]

the bad batch of transmissions are just going round and round ....

That's what they're supposed to do isn't it. 

Sorry Mel, couldn't help it. 

Do hope your not heading for more trouble.

My 2008 SLX i30 Diesel suffered from very similar issues as you described in your original post. After taking the car in for its 60000 service the car became pretty well unsafe to be on the road due the extremely long time it took to change from 1st to 2nd and from 2nd to 3rd ( in the order of 10 seconds or more and causing the RPM to spool quickly to redline), so after a few hundred km I took it in and complained. A tech from my dealer and I jumped into the car and we drove a few hundred meters and I demonstrated the fault. Upon return to the dealer I waited a short 30 mins to be handed a set of keys to a loan i30 and advised to come back tomorrow afternoon..
When I returned the following day the advice I was given was that they had flown out from either Sydney or Korea overnight a replacement 'transmission hydraulic valve control assembly' for the auto and fitted it under warranty. Needles to say I drove away happy..
I'm now at 92000km and the symptoms seem to be coming back but no where as bad as before...

I will say that the i30 auto transmission seems a bit weak. I say this as even the newer hire 2.0l autos I have used also suffer from same slow changes at 20000km under more than eager throttle. By my reckoning, Hyundai need to put some more development money into the automatic transmission in all i30 models, but in nearly every other respect the car is great!!!.

Hi everyone, I am still around....just have to much on my plate to be as regular as before.

 I have been following this thread as we also have an auto, but, being the wifes car, I drive it very litle,so am always asking if there are any "odd" noises or performances etc.

 Seems that you did very well Marcel, considering the problems of the previous members woes!!!
Which dealer did you use ?

No matter what the cause....it really makes me wonder if there will not be a flood of 4.5 yr old i30 autos on the market as the end of warranty period approaches.

  I wonder what the cost would be for a valve assembly replacement if it was being done out of warranty ?

 That is a serious question, as a failure down the track would certainly take the gloss of the diesel economy as you  reach for the wallet!!!   

 Anyone got any idea on these costs ?

It begs the question...." why are they failing and are the replacement valves any better or different to the originals...." Would sure be interesting to have some feed back from the "specialist" guy in Melbourne.

Cheers

Welcome Marcel and Hi Tony...

I still suspect that it is the more recent Auto transmissions only that have this weekness. For the first 3 years or so of the site's history Gearbox failure was almost unheard of (The manuals still appear to be bullet proof)

It seems to be only the last 12 months or so that this issue has started to surface...

I think I will start a poll 

[tla]

I was back in Melbourne for a few weeks, and was given a petrol i30 auto as a rental.

The tranny took around 2 seconds to change from reverse to drive, or vice versa.   Other shifts were normal.

That car had around 20,000 KMs on the odo.

My Beijing-assembled i30 auto has no problems, but it has only done 9,000 KMs.

Hi Guys, I know this topic is quite old, just an update from me.

My 2009 SLX i30 diesel Wagon has 86xxxKM on its meter, Few weeks ago I noticed the lag after I switched to Reverse, sometimes slam.
I went to dealer and explained to them,when the guy noticed my car is Diesel , he was pretty sure it was the valve body problem , sound this problem is very common for  i30 diesel. he mentioned it may have some problem for original valve body on diesel car, now hyundai redesigned it and the new valve body should be able to do its job.

I ended up with valve body replacement , all in warranty, all free, now the lag disappeared,  everything is fine now.

Nice to hear the redesigned valve fixed the problem and we are all happy.   My CRDI Auto is dated 11/2011 and it would be nice to know if it has the new type valve fitted.
