Code " P0741 " Hyundai Tucson 4WD - with automatic gearbox F4A42

Question

Hello,

The problem occurs under very different circulations conditions and I still sometimes several days with the engine off witness. If I have not deleted the default with my PC, the engine light cut itself off because the disfontionnement is not income.
When the engine light is on, the lock up solenoid does not work (I see that on the engine tachometer ) but if I lift the foot off the accelerator, I have still the engine brake and the engine speed redescent slowly (gearbox with freewheel)
Is it possible to solve this failure by replacing 2 sensors external speed (input and output box)
Sensor : HYU 4262139052 and HYU 4262039051

Thank you in advance for your answers

SLC.

Answer 1

P0741 Torque convertor clutch circuit - stuck off

Replacing the speed sensor will result in no correction, If any of the speed sensor was faulty you will have harsh Park-Reverse engagement shock,or Park - Drive engagement shock, and even a fail safe in 3rd gear. The speed sensor are working correctly,With P0741 this is a faulty TCC operation which can range from the TCC solenoid valve, or body control  solenoid valve,or faulty PCM /TCM.
