my torque converter clutch is stuck in off position
Service engine light keeps coming on. Code indicates p0741 and p1860. I am being told transmission needs to be removed so the harness and solenoids can be repaired. there are no other symptoms or any problems so I am researching.

nothing wrong with transmission, light sometimes goes out only to return. transmission has been working well for the last 20000 miles but now I cant pass emissions tests and there is nothing wrong but the sensor.

check engine light came on fault code for either tcc or solenoid transmission had to be rebuilt to get back overdrive
decoder reads a P0741 problem causing engine light to appear. Constantly returns if erased but have not had any problems with transmission or engine performance.
