Help please!

My automatic has a rough 1st to 2nd gear change and also clunks during the change,
Does anyone else have this problem and how do you fix this if possible.

Has it just started to happen, or has it always done it since you have owned it?

Just been through the same thing. Luckily my local holden blokes not a bad egg and they did it for me just out of warranty.
Pretty much its due to holden using the same box for both the 6 & 8 without strengthening the guts of it.
Story goes (from a transmission specialist) that due to the amount of low end torque put out by the 8's it tears up the 2nd
gear band andmakes it slip on the shaft, and it only grips when it finally catches on, hence, the sudden kick into gear.
All they do is rip out the bands and replace them with reinforced ones (kevlar i think) andgenerally need to change the clutch packs.
I didnt see the bill but it would have been right up there!!

Have you checked your transmission fluid level? If so I would recommend you book in for a service.

shockproof oil, in fact making it worst with a moaning sound during a slow turn.
