From what I've read only the line pressure can be controlled by a Tuner via manipulating the torque the ECM sees. Nothing's changed there and the trans behaves the same 3-4 but I picked up a 4-5 issue as well.
The TCM has been updated via TSB at Nissan so they say there's nothing else they can do. At this point I'm thinking failing TCM.
