im trying to figure out how a converter works and for example i'll use a 3000 stall one. ok stock i can get my truck to rev to about 1600 by holding the break now with a 3000 would i be able to to hold it to 3000 with the brake? and when i just take off my truck will roll by itself with no throttle would a 3000 one do the same. and now my truck takes off at a low rpm when i get on it so with the 3000 would it instantly shoot to 3000 as soon as i hit the gas or how does that work.

 

My truck still rolls with no throttle, even up slight inclines. I have a regular cab z71 so its a lil different. If you floor it it will shoot to 3000 and you will sling shot outta the hole, but if you just ease into the throttle you will take off sooner. And yes you can brake stall it to 3000. A 3000 stall is not a big difference in drivablilty compared to stock. you will get used to it in about 5 minutes.

3. Flash stall is the maximum your engine’s torque can stall a torque converter. In essence flash stall and full stall are nearly identical. If you had a transbrake, you could find full stall by putting your foot to the floor and reading your tach. For argument sake, let’s say we’re testing a 3500 stall Yank ST 3500. If you had a transbrake, you would see around 3500 rpms. If your motor was at idle and then you suddenly floored the throttle, you might see slightly more (maybe 100 rpm more) stall for a half second as the momentum of the motor’s internals "flashed" the converter a small bit above its true stall rating.
Brake stall, on the other hand is a very subjective thing. For most, it’s the highest stall you can achieve before your tires spin. This varies greatly based on many factors: Traction, gearing, brake clamping force, and engine torque. With a ST3500, I may only be able to get 2200rpm "brake stall" on the street with street tires...any higher rpm and the motor torque would overwhelm the tires. But if I was at the track with racing slicks on the

starting line, I might be able to get 3200 brake stall before the motor torque overwhelmed the tires. See...brake stall is very subjective.

Yank rates their converters based on their intended application. A ST 3500 will stall 3500 rpms in a stock LS1. If you had a 422 and wanted a ST 3500, the converter you received would still stall 3500 because it would be built around the torque of a 422, not a stock displacement LS1. Yank checks the stall of their converters and their competitors by using either a trasmission dyno or a "tranny tricker" in the vehicle tested. With the tranny tricker, you can place the vehicle in 2nd or 3rd gear and stab the throttle to the floor...making it easy to read both flash stall and full stall.
