My check 2001 Qx4 check light engine come on, and the code returned is: P0740. The car seems to drive okay, with no real issues with shifting.. However, on occasion my car stalls whens starting it. And while at a stop light the RPM's random drop, and the transmission feels it momentarily slips.
This code is set when the transmission control module detects improper voltage at the torque converter clutch. This can be caused by low tranny fluid/dirty tranny fluid/defective torque converter clutch solenoid/electrical connections to from solenoid
