I had a similar experience with my Tiburon. The Clutch retainers had broke and got into the differential causing the noise. I elected to purchase a Unwarranted Transmission from a salvage yard and repair it . Here is my experience / how to , it uses steps posted above and here - P0734 Transmission problems - Hyundai Forums : Hyundai Forum

Default P0734 Gear 4 incorrect ratio/P0328 Knock Sensor

I need to get my 2007 smogged but the check engine light is on and so when I had it scanned I got the P0734 and p0328 codes. I have taken it to several mechanics and they are telling me transmission needs to be rebuilt/replaced. You stated that replacing the clutch bearing solved the problem. I would like to get the car smogged and get that done if possible. If I get the knock sensor replaced will that possibly cause the check engine light to go out so I can pass the smog? Or will I have to fix the transmission first? Thanks. I don't know that I want to try and do the repair myself. I would need a video to guide me through it.

Need Help!

Default How to tell the difference

These descriptions of problems basically describe my situation. I have seen here, as well ad in other threads, the DIY repair/service to the overdrive bearing and am willing to give it a try. But I'm curious if there's anyway to tell if there's a more serious internal problem to the tranny which requires removal or is it purely a guess? At about $20 and an afternoon of my time vs. $1000 - $1500 or more, it's a no brainer. But I don't want to WASTE my time if I knew that the simpler WITT kit won't fix my problem. I don't expect an ironclad guarantee, but would appreciate any additional info.

Thanks s bunch!
