95 Nissan Maxima transmission code p 07340 p 11005 transmission is in limp mode have erased several times


what have you done to repair the fault that shows the codes?
from your statement you are removing the codes and resetting the ECM but the codes come back and the vehicle goes back into limp mode
one of the codes (p 0734 --0?) refers to gear 4--incorrect ratio===causes --wiring---TR sensor /switch ---shift solenoids---transmission mechanical fault
If that fault area is not fixed then the TCM doesn't know what gear to select so it goes to limp mode

Transmission service urgent code PO733


code refers to gear 3 incorrect ratio. causes ---wiring---TR sensor/switch--shift solenoids-- transmission mechanical fault. It is not possible to have the wrong ratio unless you have done something serious to the tranny. So the cpu is reading that the gear selected is wrong for the settings in the cpu. This means that the shift solenoid is not working properly and/or the TR sensor /switch is faulty. I would go for the sensor as it probably controls the solenoid as well. Use only genuine as cheaper units are not always compatible with the cpu.

code p 0734 refers to gear 4--incorrect ratio===causes --wiring---TR sensor/ switch---shift solenoids---transmission mechanical fault
I would check the operation of the transmission ration sensor/switch first as that is the most likely place that the fault is
check engine lights are not solely for the engine but report on transmission problems as well
a transmission mechanical fault is the absolute last that you should consider because the transmission will revert to normal operations until it selects gear 4 which indicates sensor or solenoid problem

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.
