P1779 I believe is what it was
Nissan Mechanic: Jay, Nissan Technician replied 2 years ago
P1779 is not good code. Do you mean maybe P1774?

Customer reply replied 2 years ago
P1774.We were going by memory it is the P1774.Joe
Nissan Mechanic: Jay, Nissan Technician replied 2 years ago
That code could be due to a bad TCM. Where the valve body would be replaced. A scanner is going to be required to do the proper checks to determine this. If not a TCM, it could be a internal transmission failure. Either way, it's going to require a Scanner first, if that is good, the a transmission pressure test is going to be required to determine the internal functions. If you have any more questions on this, please feel free to ask.If not, and you're satisfied with my help, please Rate me. I hope I have provided you with Excellent Service.Thanks Jay!

Jay. I have a scanner and told you what it said. Lb/c solenoid function.
Nissan Mechanic: Jay, Nissan Technician replied 2 years ago
Bulletin number NTB10-003a, For the code P1774 you need to check the TCU power and Ground. If that is good, then you need to replace the valve body. If not power or no ground, then you would need to perform the proper steps to resolve that. If you have any more questions on this, please feel free to ask. Thanks Jay

internet is pointing to this issuehttp://www.nissanproblems.com/trends/coolant-leaks-destroy-transmission/
Nissan Mechanic: Jay, Nissan Technician replied 2 years ago
That is possible also. Normally you would have a rumble strip type of noise or vibration at around 40 mph before you have trans failure. I would check your fluid condition to see if it shows any mixed fluid. If not signs of mixture, then you will need to perform the TCM inspection. As for the Trans cooler failures, There is a warranty extension based on mileage if this is your issue. http://www.nissanassist.com/web/Radiator/index.php?menu=20 If you have any more questions on this, please feel free to ask. Thanks Jay!
