Two transmissions in two months

[Airspeed]

Hi all.

I wander if there's some knowledgable transmission people that could advise here.

I purchased a 2013 3.8 V6 about 5 weeks ago with 57000 on the clock. The dealer pointed out that Hyundai had replaced the transmission after they bought the car because they noticed some bad shifting or jerking when they took their foot off the gas. They gave me the Paperwork and warranty that Hyundai had provided for the new transmission.

1 weeks ago. The transmission started really hard shifting in almost every gear. Even at really gentle take offs and slow speeds, and when I did try to put my foot down, it just revved out to 7k and didn't go into gear.

I took it straight to the same Hyundai dealer who had done the original transmission. While the car was idling and waiting for the guys to get to me, the check engine light came on. 3 days later I called and asked for an update. They said an Transmission Control Unit had been ordered. After another 2 days they called and said the Transmission mould need replacing. I asked them about the TCU and the guy didn't seem to know anything about it. When I went in, the service desk guy seemed to think it was just the TCU that was being done. When I said that I was told that the Transmission was to be replaced too and why would 2 go out within 2 months. He just said that maybe the previous transmission was faulty from the rebuild guys and that the faulty transmission had taken out the TCU. I'm thinking how the hell could a faulty transmission damage the TCU.

Finally I get a call a few days later from the parts dept reporting that my number plate that I'd ordered previous to the transmission problem had arrived, so I took the opportunity to confirm with him what they had ordered and he said both the TCU and the transmission.

It's now just over a week and I still don't have the car back, but my question is why didn't Hyundai replace the transmission with a NEW transmission instead of a REBUILT one and how could two transmissions go out in 2 months?

My personal theory is that it was the TCU that was faulty all along and the first time they had it in, it didn't throw any warnings, so they just replaced the transmission. Then maybe the un-replaced and still faulty TCU damaged the new Transmisison and now they have to replace both.

Any ideas guys?

Remanufactured engines and transmisions are not a hyundai thing. That is common practice.

I had the transmission replaced under warrenty on my 2012 3.8 at about 25K miles. It had the exact same symptoms of not engaging the next gear soon enough, making for a jerky shift. It's been perfect ever since.

Thanks guys.

They replaced the Transmission Control Unit then checked the previously replaced transmission. They found metal in the oil and when they took the pan off, they found metal chunks, so they replaced the transmission again.

It looks like the culprit was the control unit all along and damaged both transmission.

I originally thought there was a 12 month warren toy on the new transmission, but they said it just gets the remaining $2000 warranty that came with the car.

I'm thinking everything should be ok now.

The drivetrain (engine and transmission) has a warranty of 10 years or 100K miles, which ever comes first. It doesn't matter how many times they have to fix it. If you are not the original owner, then the warranty is only 5 years or 60K miles (like the rest of the car).

The warranty term is based on miles driven and age of car, not of any parts replaced. So if they replace a transmission under warranty the day before the drivetrain warranty expires, then warranty on the new transmission is only one day (technically, according to the legal terms of the warranty).

If you purchase Hyundai parts installed by a dealer not under warranty, then I believe the warranty on the new parts is 1 year or 12K miles.

Great! Thanks for the info.
