2006 Nissan Maxima 3.5 SE 4dr Sedan (3.5L 6cyl 5A)
Guys this problem is easy to fix. I have a 2006 maxima and had the same problems with the tranny as everyone else here described.
All you have to do is change your 3 linear solenoids in your valve body to so new after market ones made by a company called Rostra.
it cost $240.00 for the parts and roughly 300 for labor.
My are runs perfectly, just like new and that's all I did. You will be very satisfied with the results.
I am assuming this is whatyou are refering to
