I was driving on the highway yesterday and my truck (2006 Ram 1500 5.7 HEMI 4X4) would not shift into overdrive. The check engine light came on and I had the codes pulled at an Advance Auto...ended up with P0700 and P0740.
From what I was told the codes suggest the Torque Converter Clutch Solenoid is stuck open.
Anyone had these codes come up?...or had to replace a solenoid in the transmission?

 

I have seen them on the board before. You can do a thread search for those codes and come up with some threads to go over that might help.
