Hey guys! have lurked around this site for awhile but now I need ya help!
I've recently purchased a 08 SV6 sportwagon... (first holden)
The issue is that when cold the car is 100% fine drives and shifts just how you would expect. After you have been driving for awhile the trans seems to down shift for no apparent reason, mainly if you are coasting down a hill... It will drop from 5th to 4th then even drop to 3rd without me doing anything!! It will do this even in manual mode. It will also then turn the esp off after awhile ...
I figured it would log a fault of some description so I bought the software on elm street program... and nothing!!! not 1 fault code stored in either engine or trans!!
I've cleaned the throttle body and checked the part number which is 12615503 which I think is the updated version..
I've checked the trans fluid level which if anything was slightly over fill...
not sure where to turn from here so any help is much appreciated!
Cheers
Adam
