Is the code P0740 an immediate fix problem--7hour trip tomorrow?

Question

Do I have to repair the P0740 immediately. We are relocating to MA and I need to be there Monday?

Answer 1

P0740 Problem with lock up control system

This is for the transmission lock up torque convertor, With this type of code you do not have to repair it immediately, but you will use more fuel than required, about ten percent more. the purpose for the lock up torque convertor is to help with fuel efficiency, especially at highway use. The best solution for this code is rebuild the transmission and replace the torque convertor, You can also use a transmission additive that is compatible with Honda transmission fluid  such as Lucas transmission additive which is a transmission fluid  thickener.
