John, this sounds like a valve hanging up in the valve body. The car shifts when the govenor pressure overcomes throttle valve pressure in this valve body.
What is the condition of the fluid? Is it at all dark or grey, does it smell burnt? It should be a nice light pink. If not, have the fluild and filter for the trans changed. This may take care of the problem.
If the oil is really burnt, you are at the end of the life of the clutches and you are looking at a complete trans rebuild. If the oil is ok, a trans shop should be able to take just the valve body down, clean it and eliminate the problem without overhauling the entire transmission

From what you have described it sounds like the transmission control solenoid pack is hanging up and needs to be replaced.
When you shut the car off it resets the position of the soleniod allowing it to work for a while before it gets hung up again.
Overtime turning it off and back on again won't anymore.
Are you sure the solenoids were new and installed correctly?
Sometimes the replacments you buy are of a worse quality. Their probably is another issue causing your soleniods to wear faster than they are supposed to and when you install inferior quality replacments they may just wear out quicker. I'm not saying this your problem just an idea.
If you haven't changed the fluid and filter in a while then that definetly would be the next thing I would do before anything else.
You can check your fluid to see if its dark and smells burned or if its clean and lighter colored.
I really hope this gets you headed in the right direction and good luck.
If you feel I've helped in any way please give me a fixya rating,

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.

There is a tsb on this and the fix is to change the engine contrl
ol modul if the code is p2716. There is nothing wrong with the solenoid....the problem is the sender to the solenoid.

the first common possibilty would be to check fluid level, if the fluid level is good, I would recommend changing the transaxle fluid and filter. if this does not correct the issue, a professional transmission repair person will need to diagnose for you, good luck!
