Question about 2001 Hyundai Tiburon
I was driving along and it tried to shift into over drive. and it blew my exhaust pipe off the catalytic converter. which i fixed, but just after I realized it wont shift into over drive unless its cold. while driving it tries to shift but it just jerks the car and it stays in 3rd. I haven't done anything because i believe its a transmission issue, but I'm not to sure.i have been told that it could just need a band adjustment. please help me
Change the auto transmission fluid and filter and check the linkages
perhaps one it loose and not engaging

You need to check the transmission fluid level, if it is low the tranny will not shift. If, however, the fluid is to the proper level then you will need a new transmission.
Try putting new fluid in and look for a leak in the pan gasket, then all you may need is a transmission service. When the service is done the mechanic will look for pieces of metal in the old fluid, if found this is very bad and you will need a new tranny.
You might consider a new or used car, you can definately find a good deal out there!

Okay, I baught an 01' tiburon last march. When I first had trouble with the tranny it wouldnt shift into fourth and no it wasnt the overdrive button. Then it started downshiftling like what your experiencing then I lost reverse. Ammco rebuilt the tranny. I would take it to them, they will inspect it for free. You may just need a tran fluid flush. You should know that in the automatics the tranny is the weakest part of the car. The engines are great, just everything around them seems to fall apart after 120,000 miles.
Ammco offers a free inspection service. However Just from experience - if you need a new auto tranny it is cheaper to buy one already rebuilt (with warrantee) and pay to have it installed than to rebuild the one you have.
Cheers to hyundai challenge : )

DTC P0734 is "4th gear incorrect ratio" - that's your torque converter 'LOCK UP Clutch" It's worn out (or you're using the wrong Trans Fluid required by Hyundai - SPIII OR Both). The P1624 is simply the Trans Control Unit (computer) communicating to the Engine Control Module (ECM computer) MIL - on request signal to ECM = asking it to turn on "Check Engine" light. MIL = Malfunction Indicator Lamp. When the torque converter 'lock up" clutch slips or doesn't engage, the trans automatically returns to 3rd gear and stays there (it's called 'fail safe' mode) until you cycle the ignition key, then everything resets until the malfunction occurs again.
You'll need to have an AT (Automatic Transaxel) tester hooked up to verify this. Hyundai has a Service Bulletin specifically for "gear incorrect ratio' codes. If when you changed the trans fluid, was it done at a Hyundai Service Center? If not, someone may have installed the wrong fluid.
