Taz. Yep it was a 4l65e that came out aswell. I had never had this problem before the install. The only chages to the tune was lock up speeds and some pressure changes. I dont have a std tune to compare but I have the car booked into Holden on Friday to have the std tune installed. I will then save it my laptop and start again just incase I have a problem somewhere that I cant put my finger on. I will post tune as soon as I have worked out how to do it.
