A bit after changing my trans/diff oil, I've started to have grinding getting into 1st gear sometimes. It's not often enough that it's a serious worry, but I want to make sure there's nothing wrong with the car. I bought it used from the dealership, and I think that the previous owner may have abused the car a bit.
I took it to the dealership to have them look at it, but they told me this: before any clutch or trans work is done, a SOA rep needs to take the diff and clutch apart and make sure there's no "abuse". If they find any, I lose my warranty and get charged for the work they just did. That work is 6 hours (just for teardown and putting it back together) at $88/hour. If there's nothing wrong with it, I owe them for the 6 hours anyways.
What should I do? I really don't want to drop ~$500 for them to take a look at it. I haven't abused the clutch or trans at all, but I don't know what the previous owner did to it. They said that any abuse would have shown up before now, but I somehow don't trust them.
