These types of calculators are ok for stock stuff but once you build the trans, add servos, shift kits, change pressure and a high stall converter, they are not worth much.

The calculators are fine for analysis but for real world trans tuning the numbers are usually not accurate. Ball park maybe. Testing and tweaking the numbers in the tune are the only way to get it correct, each car is different if you want to optimize the shift points.

I gives you a starting point if you have nothing. The issue is when you add performance parts and the stall converters. If you want to shift at 6400 rpms you end up setting it to 6100-6200. If your mph shows 80, set it to about 76. The calculators all seem high, this will make you bounce of the rev limiter if you are shifting close to it.
