You disagree with the dealer? What are you doing asking us if your that smart.
Just what is a 3rd generation Maxima anyway. Is that some new year designation. I'll try that when I order parts.
Your first mistake was to change the fluid in a car that either had high mileage or already was experiencing problems. That usually takes them out completely, but hell, what do we know. We're not even as smart as the dealer, but you are.
