Help Please Trans Failsafe Mode

Dear Fellow Bimmers. Desperately need help. I have two two major issues i need help with my e53 3.0i
1. Recently had my transmission overhauled due to failure. Changed all clutches, solenoids, filter, replaced fluids and reconditioned torque converter. Trans failsafe mode error comes out while cruising at 80 to 90 mph. However, it is still able to drive normally and change gears up and down. Also occasionally does not change from 1st to 2nd gear until revs hit bout 4000 rpm while light on throtle. Error that is indicated is converter lock up excessives slip. Have so far changed converter lock solenoid, battery as well as alternator after reading numerous forums. Desperately need help as i am running out of possible solutions.

2. Another issue is error code P0161 which is sensor heater faulty bank 2 after cat. Have replaced the o2 sensor but problem persists. Also switched the wiring with bank 1 but error code still there.

Please help.

Thank you.
