Transmission question(Comp Mode)
My 09 has been doing an odd thing ever since I bought it. My dealer thinks it's normal.....I dont. Maybe you guys can help?
When I am in comp mode and I start from a stop(normal driving,no nailing it)when it shifts from first to second, the tranny slips. Sometimes if I do hammer it, it will slip too. It happens randomly. I cant see this as being normal because if you are racing, it will lose you time. Once the slip starts, you can hammer it and it will rev up and then shift. Dealer claims it is normal so the tranny wont blow apart.
It seems to do this only in comp mode. Again, I dont find this to be normal because sometimes it shifts nice and hard into second and sometimes it slips badly? I dont think that is normal by any means.
I hope I described it ok. Anyone?

What exactly is ‘comp mode’ I can not find a reference in my owners manual.
Do you mean manually shifting an automatic transmission as in a competition mode like drag racing?
I’ve never raced my HHR but I have stood on the peddle a few times from a standing stop just to see how well it will getup and go.
The shifts have been very crisp for me but I do not move the shifter manually, I just leave it in the drive/overdrive position.
The first time I did so I was actually shocked that it broke traction on dry pavement. I really did not think it would.

It,s an SS only option. Turned on it disables the TCS(traction control system) but leaves on the ESC(electronic stability control). This setting also activates the "Launch Mode" which is a rev limiter (approx.4200 rpms) that kicks on when vehicle is stopped but running(as in the starting line).

On a auto SS, there is no launch/Comp mode!
