if you have a 3200 stall converter and are driving on the highway continuously at 2800 rpm's, is the converter slipping until you hit approx. 3200. Doesn't that translate to extra heat for the converter and the trans.
Usually when choosing a converter, you will want one with a stall speed close to that of your peak torque RPM. This ensures that you "get the most" out of your engine's available power.
Let's say you have a 2000 stall converter but your torque peaks at 2800. The "loose" 2000 stall converter will launch your car before you reach peak torque, which will have a negative impact on acceleration.
Forgive me if I seem long-winded, I've been trying to choose my own torque converter lately and have tried to memorize what I've learned.
