Default Speedometer after 4l60e to 4l80e swap

My speedometer runs at 1/2 speed since the trans swap.

It's been suggested this may be causing the extremely high shift points (over 6k). Would the speedometer cause high shift points?

Any fixes?

Thanks, Jim

Shouldn't be an issue if the operating system was changed correctly. I never had an issue with mine after my swap.
