Educate me Torque converter

[Mad-Dog]

wrong again....

Wrong, Stall speed is the rpm that the impeller has to spin in order for it to overcome a given amount of load and begin moving the turbine.

When referring to how much stall speed a particular torque converter has means how fast (rpm) the torque converter must spin to generate enough fluid force on the turbine to overcome the resting inertia of the vehicle at wide open throttle.

K guys sorry for being off topic, but my truck idles very low, and I checked for vacuum leaks(wasted a whole can of carb cleaner) and found nothing. Could this be a bad t/c. And When I get on it, it feels like there was something pulling against it, (almost as if the brakes were on) Then the otherday when I moved it it idled fine and then when I got on it it hooked up, and went. Like I could bearly spin my 35's before, but I almost roasted em that time..

dude trust TJ re reabuilds tranys for a living, he knows what he is talking about.

at best even if you do you cant formulate what you want to say.

I also rebuild trans for a living-TJ is correct. One must also consider that stall speed doesn't mean vehicle will start moving at that speed. Stock is about 1400, but most trucks will move way before that. Best way to select one is to take all your vehicle specs (weight,hp,torque, gearing, tire height), or at least good estimates and call a t/c manufacturer. They will lead you to the right one for your use.
