Code P0700 telling u have tranny issue and need to be checked
this is what I have on IT
NOTE: After performing any repairs, perform powertrain verification test
DTC P0740: TORQ CON CLU, NO RPM DROP AT LOCK-UP
DTC P0740 will set if torque converter does not lock up or unlock properly. This DTC may also set if vehicle is driven over mountainous terrain. Possible causes: open fused ignition switch output circuit, faulty or stuck TCC solenoid, faulty torque converter, dirty transmission fluid, low transmission fluid level, or non-standard vehicle configuration.
1. Turn ignition on. Using scan tool, read DTCs. If GLOBAL GOOD TRIP is displayed and is equal to zero, go to next step. If GLOBAL GOOD TRIP is not displayed or is not equal to zero, tests is complete.
2. Turn ignition off. Tee in a 300 psi (21 kg/cm2 ) pressure gauge to transmission oil cooler inlet line. Ensure pressure gauge hose is long enough so gauge can be monitored during test drive. Test drive vehicle in Drive at 50 MPH while monitoring scan tool and pressure gauge. Pressure gauge should indicate about 15 psi (1.0 kg/cm2 ) until lock-up is achieved. As scan tool indicates lock-up, pressure gauge reading should jump. If operation is as specified, go to next step. If operation is not as specified, torque converter or TCC solenoid is faulty. Repair as necessary.
3. Turn ignition off. Check transmission fluid for improper level or for presence of any debris. Repair as necessary. If transmission fluid level and condition are okay, go to next step.
4. Turn ignition off. Disconnect TCC solenoid harness connector. Turn ignition on. Using scan tool, measure voltage on fused ignition switch output circuit at TCC solenoid harness connector. If voltage is greater than 10 volts, go to next step. If voltage is not greater than 10 volts, repair open circuit.
5. Turn ignition off. Measure resistance of TCC solenoid. If resistance is 30-50 ohms, go to next step. If resistance is not as specified, replace TCC solenoid.
6. Test drive vehicle and maintain 50 MPH as indicated on scan tool. Achieve lock-up and wait 10 seconds. Record engine RPM. If engine speed was 2150-2250 RPM, go to next step. If engine RPM was not as specified, differential, output shaft or gear train is most likely at fault. Repair as necessary.
7. Turn ignition off. Remove Vehicle Speed Sensor (VSS). Inspect for damage. Ensure front tires are correct size for vehicle. Repair as necessary. If no problems are found, test is complete.
