Hi, I have just swapped my 4l60e trans to a 4L80e and can't for the life of me find a stock tune that is compatible with my 01290005 COS5 to copy the trans segments. I have attached my tune and would be very greatful if someone could change the segments or email me a tune with the same OS so I could copy the trans cal. Hopefully my tune file is attached. Please email to "philkeys at adam.com.au"
Cheers, Phil
