 As others have stated - there is an inherent transmission problem with the '06 Maxima and other years as well.At 62k miles my transmission started to slip and the car jerked when shifting.I brought my car to a local transmission shop and they told me this is a common problem with Nissan vehicles.On their suggestion, I opened a case with Nissan customer affairs.They instructed me to bring it to the dealership for inspection and guess what?My car needs a new valve body and transmission for an estimated cost of $6,000 - a gross over estimate!Nissan contacted me to say they would offer no assistance.Everyone with a similar problem must join the class action suit underway!
