I have question related to the transmission. The car start slip gear when I shift to D4 or 1, 2 or D3, the RPM jump to 2000 but the car doesn't move much. The CEL on and I pulled out the code P0740. I right away changed the transmission fluid, unussually in the old transmission has a lot of metal deris. I also troublshoot and clean Lockup Control Solenoid Valve Shift Control Solenoid Valve A and A/T cluth Pressure Control solenoid Valve A/B. All of two unit above pass the Ohm test within the range and click sound heard when test. Also no futher code fail for the 2nd, 3rd clutch pressure switch. The car run fine after I changed Transmission fluid but the unfortunatelly, the CEL still on with code P0740. The RPM also some time jump little on low speed 10 or 20 MPH or when I stop on the red light or Stop. Please let me know what wrong cause for the code P0740? Is the Torque converter failed or the whole transmission dead? The car run fine but still had error code P0740 and RPM will jump when slow speed.
have the same problem?
