Grinding noise when shifting from 1st to 2nd gear?

Okay, this problem just started today and I am lost as to what the issue could be. When I attempt to shift from 1st gear to 2nd gear seamlessly there's a very noticeable grinding noise. The clutch is totally pressed in and I've been driving nothing but manual cars since I was in high school (several years ago, hehe) so I know that's not the problem. I am worried that if I don't have it checked out it could persist and get worse. Again, this just started today and unfortunately my warranty ran out 8000 miles ago (ugh!). Any insight would be appreciated. Thanks in advance.

Start by getting your gear oil changed.
It could be the viscosity has broken down and thinned to the point lubrication is lacking.

I've had the car for about 15 months now. Yes, I suppose there have been times that I have powershifted (who can resist!?). Should I just take the car into Pontiac and let them look at it? Is there a way for me to change that oil on my own or is that something that a mechanic would have to do? Thanks for all the help.

Also, is there any chance of this getting worse or that it'll lead into other issues if I don't get it looked at/fixed soon? I was going to take it in today but I have to work and then I am out of town the week after that (using my car).

YES it can lead to other issues. Constant griding of the gears will wear the teeth on the gears and can even break them off as the condition worsens and you apply more force.

Well, I'll be out until Thursday evening of next week and then I am off on Friday so I'll have to take it in then. The car will just be sitting at the airport until then so no big worry I suppose. Thanks for the help.

You know, I've noticed that people who are having all these tech problems are leaving out a lot of things...like beating the crap out of the car. I mean, I drive my goat the way it was made for but I don't beat on her and that is what I think is happening.

Hi,

Maybe the clutch or clutch hydraulics??

Try cranking it in first gear (Clutch In). Do you feel any resistance, or does the car try to pull off?
Also, when it cranks in first, can you shift it into neutral, easily?

Just a hunch.
