transmission, stall convertor question???

alright here we go.....my car has had some work done to it before i purchased it, dont know if the tranny has been programmed, shift points, harder shifter or if a shift kit has been installed or more, but its NOT stock!!!! anyway, how does a stall work? the reason I am asking is all I know is that a stall lets you raise the idle more before the car actally tries to take off, I think? anyway, under normal driving conditions if you have a stall will it feel like there is a lag when you just take off normal from a stop? it almost feels like slippage, but it just like 200 rpms then takes off, just normal stop and go....is my tranny going out, or possibly have a stall in it? also, i really havent tried to see how far i can sit and stall it up before the wheels turn, but its somewhere in the neighborhood of 1500 rpms or so, if that helps??? thanks in advance!!!!

Of course you have a "stall" in it. EVERY torque converter has a stall RPM (or, as GM calls it, K-Factor). Depending upon your engine/trans/year, the stall RPM from the factory can be between 1,211 RPM and 2,025 RPM. An older converter that has been beaten on can have an even higher stall RPM.

Lol, apparently your a fbody.com member too. They gave you the correct advice over there. Brake stall it and see. I tend to think you don't have a stall cause I have a friend with a 97 Camaro and a stock stall that doesn't cause tire spin til around 1300 - 1400 rpms. While thats a little high, its not unheard of. Also, how many miles you have on the car?
