Hello and thank you for your question,Is your M35 equipped with the 7 speed trans?
Nissan has released a service bulletin dealing with the proper way to fill this transmission and it dose require a special procedure . I have enclose it in the link below for your review. If you follow the steps as shown this will tell you weather your level is correct. Also be sure to use the recommended fluid in this transmission.https://dl.dropboxusercontent.com/u/104923897/ATF%20Jul%2021.pdf
You can usually just warm the engine up and you should be fine with the temp. You need to follow the steps to the letter and I suspect you may have lost more then you think when you drained it and yes you have to overfill it to know when its actually full so follow the steps in the bulletin and if the problem is due to being low on fluid then this should solve the problem for you.
Sounds good, Im here if you need me.
