Hello, I was driving on the highway and all of a sudden my car  gave me a P0777 code. It is saying that the solenoid is stuck on. The car will go to reverse but will not move and when putting it into 1st it will automatically skip to 2nd gear. In 2nd gear the car will move.

 

The oil pressure looks good on the MFD. I am planning to get the transmission fluid changed and have the solenoid checked out. Before I do that I was curious if anyone else had this issue? 

 

This is a crappy first post but I guess it forces me to ask for help instead of just reading the forums. Thanks for any inputs.

We just fixed another one doing the same thing. You likely have some failed gaskets. The trans will need to be removed, disassembled, and repaired. I can help set it up for you if you want.

Instead of trying to figure it out Doug gave me a great deal on a transmission.

Try a valve body clean first and fix your tm oil pump seals. I had P0797 first fixed the oil pump seals and gone.

 

Some old photos from 2013 when I did my gearbox.

Been working with enshiu on my car for the past 2 days. This guy is a mad scientist. He knows his stuff about GT-Rs. We spent the past few days changing brakes, rotors and upgrading my  gotboost full intercooler piping. Enshiu will post pics of my car later.
