My 2000 hyundai elantra is automatic it has a code p0734. which the mechanic explained me that i have to get the speen sensor replace and get new clutch because the 4 gear ratio is bad. pls advice what 2...


P0734=A/T 4th gear incorrect ratio. This has nothing to do with the speed sensor. If the speed sensor was faulty, it would also set OTHER gear incorrect ratio codes. My experience tells me the 4th gear incorrect ration indicates the torque converter clutch (TCC) is slipping and nothing more. Unless there was a speed sensor DTC (Diagnostic Trouble Code), the sensor is not the issue (yet). The fact P0734 was set (trust the computer), the TCC is slipping (out of range). Question: Maintenance history may indicate the wrong transmission fluid may have been introduced. Hyundai's Transmission fluid is strictly SPIII... there is no substitute. The incorrect fluid will cause 4th gear slippage. Now, having said that, it doesn't mean the 4th gear (lock-up) clutch isn't worn out. Have a qualified/certified Hyundai Service Technician properly diagnose this issue.

Code po734, po735


This is what your codes mean:

Trouble Code-P0734 (A/T Additional Gear Ratio Error In Fourth Gear)


Trouble Code Conditions:
Vehicle driven to a speed of 4-37 mph at more than 500 rpm, gear selector in 4th Gear in Drive, and the PCM detected too much difference in the engine speed and output shaft speed.

Possible Causes:

  • Customer may complain of intermittent 4th gear operation
  • O/D and 2/4 pressures less than 75 psi
  • O/D or 2/4 clutch volume indexes out of specification
  • O/D accumulator seals are damaged
  • Transmission enters "limp in" mode running in 4th gear

Trouble Code-P0735 (A/T Gear Ratio Error Fourth Prime)

Trouble Code Conditions:
Vehicle driven any forward Gear, and the TCM detected the ratio of the Input speed to the Output Speed did not match the current Gear Ratio (this test can take up to 5 minutes).

Possible Causes:

  • Related Gear Ratio trouble codes may be stored (note that some of these Gear Ratio trouble codes may be intermittent)
  • Transmission has internal problems or damage present
You have a transmission problem.

    It seems like you were having an issue with your transmission but if you cleared your light and it has stayed off I would just keep a close eye on it.

    2001 Jeep Grand Cherokee won't shift out of first gear and the fault codes are P0733 and P0734.


    P0733=Gear 3 Incorrect Ratio
    P0734=Gear 4 Incorrect Ratio,
    your transmission is in "limp" mode,
    Have the following sensors checked on the transmission,input sensor,output sensor,and speed sensor.
    The transmission is not getting a signal from one of them,So it doesn't know how fast your going so it doesn't up shift.
