Smile Oil Leak was a bad Torque Converter!

I had a warranty repair done about 2 months ago for a suspected bad rear main seal on my 2010 3.8 Coupe. Everything was ok until 2 weeks ago when I found another oil puddle under the car. It was coming from the tranny bell housing so I assumed it was the same leak. I took it to another dealer in South Georgia (Langdale Hyundai - which were great) and they inspected it and found the rear main seal was fine.

After looking further they found that it wasn't actually an engine oil leak, it was a bad torque converter and it was leaking transmission fluid. The tranny fluid was pale brown - not red - apparently Hyundai uses a German fluid that never requires flushing or servicing and it costs $65 a QUART!!

There was a hairline crack on the output shaft of the converter that was barely visible. I had to wait a week to get the replacement converter in from California but they gave me a loaner for the entire time my car was in the shop. Now it's installed and I've got my baby back - everything covered under the warranty at no cost to me!!

I just wanted to recommend Langdale Hyundai and say thanks to Christine (Service Manager) and the parts manager who actually saved the converter to show me what they found. I bought the car used and the deciding factor was the Hyundai 5/60,000 warranty and my decision paid off.

thats good to hear.

FYI for other reader that want to crack apart the engine and trans, for whatever reason.

torque converter HAS to on the input shaft of the trans BEFORE mating the engine to the trans.
to bolt the converter to the flexplate (if not fimilar, its the automatic equivilant to the flywheel) there is a plastic access cover on the very bottom of the engine.

If you bolt the converter ot the flexplate before mating the trans and engine, you are going to tear seals and o-rings. these rubber pieces are made to be around ATF, and cost a lot more than you think.
