Hello,
I have in Australia a 2007 Astra SRI Coupe with a 2.2l Direct Injection petrol engine mated to an Aisin 4 speed Auto trans.
I am wondering if anyone can answer my querry as the local dealer did not seem to know or understand.
When travelling down steep hills and you apply the brake the trans downshifts to 3rd (sometimes harshly)
Is this common to all Astra
Thanks

Subi
