Just got a CEL yesterday on my 05 WK Ltd. 4x4 4.7L. The code is P0740 and it pertains to the torque converter selenoid circuit. I disconnected the neg terminal of the battery and it cleared the code. I've driven it a little today to see if the code comes back. So, if it comes back what are my solutions? Is it ok to drive while the CEL is not on? I need to drive to Miami tomorrow and it's a 5.5 hr drive down and back from Jacksonville. I'll be gone until thursday. Should I just rent a car and deal when I get back?
