Can someone diagnose this??

Hi, I have a 07 Ve sv6 that makes a strange noise when in sports shift (automatic car) I'll start off in first and put my foot to the floor let it get into the 5-6k revs and then shift it into second but just about everytime when I bring the revs that high in 1st gear it will hesitate a little and keep going up to around 6.5k revs then jolt and make a squealing noise, I suspect a timing problem but I'm not 100% on that... can someone help me? Cheers for any help

Another one trying to break it.

I obviously know this isn't good for the car whatsoever but that doesn't really help me, not trying to be rude

Have you serviced your trans lately? I’d try that for a start

Belt slip?

No I haven't, I might have to next service

Belt slip?

Could be, is that just something that happens sometimes or is it indication I need a new belt?

Few more tries, you might not need to service it.
