Trans overheating problems
My 2005 Dakota has been having transmission overheating problems and a hesitancy to shift into overdrive/4th. I have drained and flushed the fluid, changed the solenoid pack. The radiator seems fine and so does the coolant.
It doesn't seem to be a faulty temp sensor because the fluid because the fluid feels boiling hot on the dipstick.
I do not think it is the trans speed sensor because cruise control seems to be functioning.
The coolant is clean and the radiator is not overheating.
I have tried looking for the check valve on the return line but could not find one. Is there supposed to be a check valve for the 42RLE trans?
What should my next step be?

P0700 is a generic Transmission code. P0740 for the 42RLE is a Torque Converter Clutch out of range. According to FSM, it's either the Transmission internals, or the torque converter itself in the absence of other codes. I don't have a lot of experience with the 42's so hopefully someone else will chime in.

Trans over heating
I had this problem just after I purchased. After have the transmission rebuilt twice. Trans people couldn't figure it out. Finally a friend used a laser temp meter and found the hoses run right next to the catalytic converter. The catalytic was going bad and heating the fluid as it came back to the trans. Replaced the cat and haven't had a problem sense.
