NEW!!!

I will make one calibration change for an additional $100 per change. For example, changing a shift point for a given gear is $100 vs changing a shift point and a pressure setting would be $200. That value can be used towards the full custom tuning price.

built 6l90 shifting issues

2012 ctsv with a built trans (not sure who built it nor what brand parts were used). 

My buddy came to me with the trans issues, shifting is very inconsistant sometimes it'll shift decent and other times not so much.

as you can see from the log it shifted way too early on the 1-2, and I cant even explain whats happening on the 2-3 shift.

I did ask to check oil level and over fill as needed.

ANY HELP IS GREATLY APPRECIATED, THANKS!.
