4L80E Shift Points and Lockup rpms?

[DA BIG ONE]

Any of you know the shift points in rpms, and lockup rpms for the 4L80E.

What would be the best way to change these points up or down to better suit my application?

I changed from 4.10 gears to 3.73

The OD TCC lock up changed from 45 to 50 mph.

I believe the TCC lock up speed is controlled by the
PCM ( Tran controller program ) and it uses
Transmission tall shift speed sensor.

Do not believe you can change this.

When recalibrating my speedometer, with a gps
as MPH ref, The TCC lock up speed did not change.
50 MPH in OD and 3rd gear. No mater what the speedo indicated.

The only way I know to lock up TCC at lower MPH
is with the resister in the temp sense line ( see posts ). Than this only affects 3rd and 2nd lock
up speed: 28 mph in 2nd, 40 mph in 3rd. with
3.73 gears.... OD Stayed the same ( 50MPH )
but would stay locked until 3rd downshift...
