That codes is a wishy washy code with many different solutions if you search P0741.
On this particular car which was a 97 900 NA it turned out to be the customer had installed after market spark plug wires and they bled off to much voltage into the wire harness and it disturbed the crank shaft or camshaft position sensor making the car believe the torque converter did not lock up properly. You see how engine rpm is fluctuating even though the gas pedal is held at steady speed and not fluctuation in engine speed was noticed.
Other posts say they got rid of it by changing the fluid and other say the code was cured by replacing the gear selector switch.
Since yours is a turbo, have you replaced the ignition cassette with an after market one or some strange spark plugs?
