Upthewazzu Just got the word from the dealer today that we're getting a new (most likely reconditioned) transmission @ ~62,000 miles. We've had issues since almost day one, but had the usual "reprogramming" done which seemed to have cured it until the last 6-8 months. It became very bad; refusing to shift until very high RPM and then banging into the next gear, general hard shifting, even popping out of gear twice. Anyways, I'm actually glad that they're replacing it since we're still under warranty.

Tripplec I was just thinking of that. The moisture is not going to get into the transmission. I would suspect the control model and/or computer connections contacts. I don't know where they are. But pulling the -ve battery cable before pulling them off. I would hit the contact face with Electronics Contact Cleaner spray. It evaporates quickly of course longer in the cold. The weather seals my not be good or retainers not holding the connect tight. But something on that area. The harness itself would not be the problem unless damage for rubbing somewhere occurred and/or an accident has done something.

Of course the grounds are also key although I don't see moisture making a ground worst and good again when its dried up. A head scratcher for sure.

Same engine, 3.5L and auto tranny. Hyundai should have fixed the bugs by the 2nd year (after 2010). If I was going for a new model 2012 would be the safest from what i have read.

Nick Maio Seriously - - - something is strange.
Dampness sounds like something something electronic - not mechanical.

Have you spoken to a dedicated transmission shop in your area = a shop that only works on transmissions.

Many dealers are a swap shop and not mechanical garages - especially in this instance.

2014ElantraLOwner Tripple, do you have any idea why the truck works fine with no issues and only develops problemswhen its damp?

Im just confused how this situation requires a full swap? For that wouldnt it require that the problem present itself regardless of the weather conditions?

Check with transmission shops as dealers are always very high priced. Then decide what to do. If going new wait until the model/make has a promo sale on as most do for better prices.
I will not be looking for a new vehicle.

The transmission of a 2012 will fit in the 2010? Are they the same?
I was thinking of maybe look at a 2011 or 2012 model but if the transmission is the same Im going to rethink that.

2014ElantraLOwner So I heard back from the dealer today.
They tested the transmission.
Found no issues with the solenoids, found no problems with the continuity or any problems with wiring.
They found rough shifting and their recommendation is to replace the transmission.
I was quoted $3000Cad for a new transmission plus labor (about $1100.00) or a used one that they found for $2500 installed. According to them it has 75000km.

The used one is problematic for me because who guarantees me that in 30-50K it will not have the same issue and paying 3000 bucks for a new transmission to put in a 6 year old vehicle doesnt sound like a wise investment.

The other option is to trade it in for another vehicle and get rid of the problem.

2014ElantraLOwner I now have what I think is the cause of the problem.

Dampness or rain one or the other or both.

I took the truck for a drive at lunch time and all the symptoms came back, the clunking, the locking into 4th gear and the engine light with the error code P0764.

Whats different today from yesterday and the day before and so on?

Today it raining and the temperature is +8Celsius so its very damp in the air.

So would this mean that its a wiring problem and if so its the wiring harness the problem and that means still opening the transmission again?

2014ElantraLOwner Today I was going to drop the truck at the dealer in the afternoon after running some errands into the city.
Its a 100km drive to the city with about 80kms on highway.

The truck has worked perfectly fine today/
No issues on the highway ( even using the cruise control) driving in Drive mode.
Got into the city early morning and with lots of stops and go driving all day long.
No issues with the truck.

Because the truck in the past few days has not shown any symptoms and today worked fine after driving about 300km's I decided not to leave it at the dealer.
So drove back home and nothing. ran just fine.
I feel that at this time they would not find anything wrong with and would just be a waste of money.

I am hoping for a damp day soon because that seems to be common factor when the truck exhibits the problems.

Stiff tranny shifting

I have a 2010 Santa Fe with 80K out of warranty. It had a clunk into 2nd when cold and sometimes (but rarely) just shifting into gear when cold.

Took her in and change to Red Line D4 and what a great difference! Smooth, clean shifting.

That was 10K back and no problems. Have converted all my vehicles to Red Line synthetic ATF and am very happy.
