[CL9] Auto Shift not working

Hi guys, I've tried searching around if anyone else had my problem but no luck.

So basically I have the Auto 2005 model and when I switch to Manual I can't seem to shift Up! I can shift down gears easy, but when I try to "tap" it upwards nothing will happen.

Anyone know why?

Thanks in advance.

what RPM are you trying to shift at?

the computer's smart enough to prevent you form shifting too early.

I think 4-5k? How high should I be going?

give it a firmer tap.

I'll give it a shot

Tried it again the other day and no luck, probably should of tried it without other cars around me (made me look like I was trying to hoon)

Any other suggestions?

Take it to a mechanic.
It should change gears easily.
