dtc p0741,p075b,p2757

Hello, how many miles on this RAV4? There should be a 5 year / 60,000 mile powertrain warranty that may be of help to you. P0741 and P2757 relate to torque converter operation. P075B, although I do not see it listed specifically for a RAV4, typically relates to shift solenoid "G". Is this a RAV4? I don't show a RAV4 having a CVT for 2014 -- in North America at least. In any case, hands on testing with a diagnostic tool capable of analyzing data streams and monitoring shift solenoid and torque converter clutch operation is required. Ensure fluid is at the proper level, clean and not burnt.
