Small changes can make HUGE impacts, especially with the governor pressure.

Also, remember, most of the parameters are based off of output shaft speed and throttle percentage, so knowing the output shaft speed you're playing with is important.

I attached a very basic calculator to use for output shaft speed. It's not dead on perfect, but it gets you close. All you need to enter is RPM, gear ratio and tire size and it will calculate the shaft speed, etimated vehcicle speed and tire rev's per mile.

Rich's calculator is what i used to get my trans working to my liking!!!
