Your transmission fluid contain water,thats why the colour of the fluid changed to pink.And of such the clutch is slipping causing the engine to reve up before shifting - Check transmission cooler.

some of the trannys has straps in them that sometimes needs to be tightened and that could be the cause of it
SOURCE: trans drops into 3rd gear won,t shift to 4th
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.

Well, there could be several possible problems. It is not uncommon to have a little harder shifting after a fluid change for a period if the system was low prior to the change however, If you had the fluid changed using one of those reverse flush machines I see the problem getting worse. Most stations want to use the back flush system to do a fluid change now days. That is because the newer model vehicle have a metal filter screen which is re-usable and is designed at the factory to use Synthetic Fluid. In the older model vehicles, 2000 to 2005, manufacturers where still mixing the types of filters that were being used. This model has a standard filter that model uses the newer filter. If you went to Jiffy Lube and didn't specify you wanted a regular Fluid and Filter change they hooked it to the machine and charged $140+ for the job. A regular Filter and fluid change with regular fluid would have run about $50. Every time, and I mean Every time, I have had a fluid change using that back flush machine on a vehicle within 6 months I have had to have the Transmission repaired at a shop. If you didn't have the fluid changed using that backflush machine then your problem is just adjustment to the new fluid being at the proper level. If you did, start saving for a Transmission rebuild at a shop, it's not far away.
