Problem with shift interlock system .
Automatic Transmission Shift Lock Control Description and Operation
The automatic transmission shift lock control system is a safety device that prevents an inadvertent shift out of PARK when the engine is running. The driver must press the brake pedal before moving the shift lever out of the PARK position. The system consists of the following components:
?€¢
The automatic transmission shift lock control solenoid

?€¢
The body control module (BCM)

?€¢
The powertrain control module (PCM)

With the ignition in the ON position, battery positive voltage is supplied to the automatic transmission shift lock control solenoid. The automatic transmission shift lock control solenoid receives a ground from the BCM. When the automatic transmission shift lock control solenoid is energized, the shift lever mechanically locked in the PARK position. When the driver presses the brake pedal the PCM sends a class 2 serial data message to the BCM. The BCM turns OFF the ground control circuit and this de-energizes the automatic transmission shift lock control solenoid. When the automatic transmission shift lock control solenoid is de-energized, the shift lever may be moved out of the PARK position. The BCM determines transaxle shift lever position through a class 2 serial data message from the PCM. The PCM receives inputs from the park/neutral position switch and determines shift lever position. When the BCM receives this information and determines that the shift lever is out of the PARK position, the automatic transmission shift lock control solenoid ground is opened.

is it a linkage issue? if the shift lever is working and you can feel the detents, check your fluid make sure it is full and clean, if not you could have internal issues with the trans

Does the engine start ? Is this a automatic transmission vehicle ? Do the brake lights work when you press on the brake pedal ? It probably has something to do with the Automatic Transmission Shift Lock
The brake transaxle shift interlock (BTSI) system consists of the body control module (BCM), powertrain control module (PCM), BTSI solenoid, stop lamp switch, and PRNDL selector switch. The BTSI system prevents the driver from moving the shift lever out of PARK unless the brake pedal is depressed while in RUN or CRANK.
The BCM controls the output to the BTSI solenoid by grounding the solenoid which energizes it, preventing shifting out of PARK. When the BCM receives input from the PCM over the Class II link that the transaxle is in PARK and the brake pedal is depressed, it will stop grounding the BTSI solenoid or de-energize it which will allow shifting. After the transaxle is moved out of the PARK position, the BCM shall monitor the status of the PRNDL serial data message sent by the PCM and shall continue to de-energize the solenoid until the transaxle has been returned to the PARK position.
In the event that the serial data messages are never received (approximately 5 seconds) by the BCM from the PCM, the BCM shall de-energize the solenoid to allow shifting. The transaxle can be shifted from PARK by placing the ignition switch in the ACC position. This eliminates power to the solenoid.

Do you have column or floor shifter ?
All automatic transaxle models use an electric park lock system. Within the housing assembly, a lock cylinder is connected to an actuator which rotates and engages on the electric park lock solenoid. When the floor-shift lever is not in the park position, the actuator disengages from the electric park lock solenoid slider. This allows the lock cylinder to move to the lock position. With the shift lever in PARK and the lock cylinder in LOCK, the actuator cam is positioned against the electric park lock solenoid slider. This prevents the shift lever from shifting out of the PARK position.
The column-shift automatic transaxle model uses a flexible cable actuator instead of an electric park lock system. One end of the cable is attached to the gate assembly. The other end of the cable is attached to the column mounted housing assembly. This system functions similarly to the floor-shift ignition lock system.
The manual transaxle model uses a push button lock cylinder. A clutch start switch is used. The clutch pedal must be pressed before the engine will crank. Refer to Park Lock System Check .

The gear selector does not shift out of PARK with the brake pedal depressed and the ignition switch in RUN.

Do you know what a DTC is ? Diagnostic trouble code !

DTC B2708
The body control module (BCM) controls the automatic transmission shift lock control solenoid. Positive voltage is supplied via the ignition 1 voltage circuit to the automatic transmission shift lock control solenoid. The BCM controls the ground circuit of the automatic transmission shift lock control solenoid . When the brake pedal is depressed, the BCM removes the ground allowing the solenoid to disengage. This action allows the vehicle to be shifted out of the PARK position.
Conditions for Running the DTC
DTC B2707

Your best bet mite be to have a qualified repair shop check it .

Hello, all your codes are related to transmission shift solenoid circuit condtion eg: Transmission > Automatic Transaxle > P0750 Low and Reverse Solenoid Valve Circuit - Open or Short(GND). Automatic Transaxle > P0755 Underdrive Solenoid Valve Circuit - Open or Short(GND). Automatic Transaxle > P0760 Second Solenoid Valve Circuit - Open or Short(GND). Automatic Transaxle > P0765 Overdrive Solenoid Valve Circuit - Open or Short(GND). Wether your vehicle is equipped with a 4 cylinder or v6 ,all the codes are for either engine models. Check your main wire harness that plugs into the top of the transmission and verify,that a good connection is present. if all looks ok and the vehicle still exibits the same symptoms. The problem may also be in the ECM/TCM control module itself. A Hyundai dealer would have the proper scan tool and tester to verify and perform actuation tests on the shift solendoids themselves to make sure they are working correctly. This does not mean that the transmission itself has failed. You basically have an open circuit somewhere that the solenoids are not getting a good ground. Hope this helps.

2. Disconnect the transaxle wiring harness.
3. Remove the 2-3 shift solenoid (315B).

==the torque converter solenoid--inside tranny too

good luck,let me know

your trans has lectronic controls to operate the shifting of your trans. If there is a defect, a fault code will be stored in the computer, called a DTC. You need to have someone with a scan tool check for the fault code. It is likely a solenoid that is not working or stuck.

Get the codes first. Autozone can run the test for free on engines, maybe trans codes too. Call your local Autozone or big parts store and ask them.

---------------------------------
You may need your PCM, Powertrain Control Module reflashed by a Ford Dealer.
Try disconnecting your battery for 1/2 hour and then reconnect and see what happens. It will run a little rough and shfit hard until it relearns your engine/trans characteristics.
Let us know results of tests and DTC codes if you get them.
