2005 Nissan Altima. Noticed transmission slipping at 59,000 miles. Took to local dealership at that time. They refused to even consider it a warranty issue because the transmission fluid was not changed at 30,000 miles. Owners manual has several maintenance schedules. Mine falls into the category of substantial hwy. Driving and does not require the fluid be changed until 100,000 miles. I continued to pursue the claim even after the 60,000 mile warranty expiration period. I am now told that claim will be denied because a diagnostic test was not done when I took the vehicle in at 59,000 miles. The dealership changed the fluid on my first visit (at my expense) and very bluntly told me that if the problem persisted, I was on my own. They never offered to do a diagnostics test. The dealership finally did a diagnostics test at 67,000 miles and determined that the transmission was bad, but they will not replace under warranty.
