If you didn't read BoostN's attachment it kinda goes like this.
Truck/Car level
start motor ensure trans fluid temp between 86*F and 122*F
rev motor to 2000 rpm to fill torque converter
Go to idle
run trans through all the gears for 10 sec each gear
Make sure temp between 86 - 122 If high turn off motor till temp is back in spec
With Engine running Remove oil fill plug
If fluid runs out let continue till it reduces to single drops.
If no fluid comes out then fill (while motor running) till fluid starts to come out
Reinstall fill plug
The End or "That's All Folks"
I plan on ensuring my temp is as close to 86*F as possible.
