Transmission problem

when troubleshoot tested the code P0744 comes; when accelerating from the stop position the car is very sluggish and after changes gears erratic although at higher speeds behaves somehow normal; also on the test sheet the following is written: data monitor-atf temp 2-83*c, ATF pres sw1-off, ATF pres sw2-off, ATF pres sw3-off, ATF pres sw5-off, ATF pres sw6-on, SLCT lvr posi-n/p, TCC solenoid-0.00, LINE pres sol-0.00; detection condition: dtc is detected when A/T can not perform; lock-up even if electr. Circuit is good; reccom: check: torque converter clutch solenoid valve or each clutch or hydraulic control circuit. Please analize this test results and give me the exact diagnosis and repair guidence. There is no dealer to consult nearby> Thank you.
