They're giving you the run around... look at your warranty book, in bold print they have this line "What is covered" and it lists the transmission and everything. I'd have to run out to the car to get the book, but someone here might have it handy. I actually had to get it out to show the isuzu dealer for them to believe me. They were like "man, that's a good warranty"...... Right now i have a slight knock in the steering, if I jiggle the wheel from left to right I can hear a click, so I'm going to have that checked out and the entire steering mechanism is covered as well. This warranty does cover tons of things you wouldn't traditionally think of "powertrain". Now if I can just get them to replace my blistered wheels....
