Vehicle wont change up into gear reverse gear not

P0755 Shift Solenoid B Malfunction
cam not find the P1529 you can call auto zone maybe they can help

The problem is a gear internal failure the gear who drive the speed sensor is defect the is why you don't have speed sensor reading. There is a way you can verify that remove the speed sensor drive it with a drill check the dashboard you will see.

code P0732 - gear 2 incorrect ratio possible cause solenoid or related pressure switch is damaged or failed. problem related to the input speed or output speed sensor.low reverse clutch is damaged leaking or failed.faulty valve body. transmission fluid level incorrect or level is too low. code P1529 -

code p1529 refers to transmission control module-communication===causes --wiring-TCM and ECM
code p0723 refers to output shaft speed sensor (OSS)-circuit intermittent==causes--wiring--poor connection--OSS sensor --ECM /TCM
n both codes the TCM shows and the wiring may be a loose /dirty connection at the gear box level

SIGNAL ON BUT THE GEAR 4 NOT FUNCTIONING WHY ?

P1529 - MIL light request

P0722 - Transmission Pulse Generator B. The Pulse Generator detects the revolution of the idler gear parking pawl lock gear and emits a pulse signal. The pulse signal is sent to the Transmission Control Module (TCM) which converts it into vehicle speed. The code is detected when the Pulse Generator B failed to provide a signal to the TCM upon initial movement of vehicle.

Symptoms:
- Engine Light On (or Service Engine Soon Warning Light)
- Speedometer improper reading
- Possible shifting problems

Possible Causes:
- Pulse Generator B harness or connectors
- Pulse Generator B circuit is open or shorted
- Pulse Generator B

Sounds like a dirty of faulty speed sensor. They can be removed and cleaned. Better off replacing. Do check the wires to the speed sensor. Trace wires from tranny to instrument cluster and make sure they are all in tact and clean.

P1529 indicates that the TCM [Transmission Control Module ] has requested the engine control module (ECM) to turn on the check engine lamp. P1529 is related to your vehicle speed sensor problem.

Whenever the 'CHECK ENGINE' light comes on, the ECU (Engine Control Unit) sets a Diagnostic Trouble Code (DTC). These codes identify the particular engine management system which caused the light to come on. P1529 is a TCM MIL request to the
ECM.
TCM = Transmission Control Module. The sluggishness is really what is known as 'fail safe' mode (3rd gear). You should have had other codes besides P1529 to identify which system in the transmission caused the problem.

P1529 means nothing more than the TCM (transmission control module) has requested that the ECM (engine control module) turn on the check engine lamp.
P0734 basically indicates that your transmission is slipping.
You need to take this car to an authorized repair center for hyundai cars. Replacing the filter and fluid on the transmission might save this transmission but I would be willing to bet that a total transmission rebuild is in order.

Good Luck
