Transmission issue . Has been happening for some time. Took it originally to Holden to have it checked out and they were too busy, then ended up taking it somewhere else and the transmission was failing.
Then i took it to rapid tune and Shaun checked the whole system and advised that it has failed the transmission system and needs to be replaced. And then he took this back to Holden to have it under warranty ,which of course has expired by 4 months but after Shaun explained the condition of the system to Holden considered to replace under warranty.
i got the car back from Holden with new transmission system with out spending money my pocket. Big thanks to Shaun who helped me to get this sorted.

Many thanks Shaun:-)
