simple question...what exactly do they do, just raise the rpm where it transfers all the power to the tranny? how exactly can this help me, and how will it affect daily driving, such as gas mileage etc.....fun factor(not for just racing hardcore), also are they harder on the trans. then the stock one....

Just like manual transmission cars, cars with automatic transmissions need a way to let the engine turn while the wheels and gears in the transmission come to a stop. Manual transmission cars use a clutch, which completely disconnects the engine from the transmission. Automatic transmission cars use a torque converter. Stall speed should be matched to engine performance, the car weight, tire size and gear ratio. Proper selection of stall spec will make for quicker launch, better 60 ft. time and better ET. It is very important that these parameters be specified when ordering a converter to assure satisfaction. For a stock car 2800 to 3000 stall is a good choice

what about implecations on daily driving? also about the stall..so basically if the stock ones around 1800, and i can only stall to around 1500 w/o doing a burnout, so with a 2800 stall could i stall to 2800 w/o doing a burnout?? also how would it affect rolling start performance, also any affect if i kiked down at 65 for passing or anything?

Normal driving is not affected by stall speeds up to approximately 3000 RPM, particularly with a good converter. A car will begin to roll normally when a higher stall speed converter is used. Quick acceleration will be favorably influenced by stall speed. A very high stall speed (above 3000 RPM) would not be satisfactory for street use. For more bang for the buck combo tc with higher gears will give you that rolling start performance your talking about, but then your gas mileage goes downs big time, so its up to you what kind of setup you want

well ive had my tc in for about 3 weeks now and i love it, my converter locks up when i shift if the overdrive and driving is like a normal converter, i just tried my dr's out and stalled it to about 2500rpm or so and bout broke my buddies neck lol, the stall in my view is the best bang for the buck for an auto car, it helps out in all rpm ranges at any speed, lets say the 40 spot, i have 2:73s in my car and with the old converter is was a big dead spot, well the stall will eliminate that dead spot for you, for me on street tires i could only stall it to about 2200rpm, i dunno what it will stall up to on the track, but i'll let u know friday night

so will it affect normal shifting and shift points when accelerating normally? how about gas milage?

It shouldn't effect your shift points, those are decided by the PCM. The shifts may even be softer, since the converter is looser.

Gas mileage may be a little bit worse... depends on how much city/highway driving you do. To get your car moving, it will take some more rpms. Once you're cruising, it should be like stock. So if you do alot of city driving, your gas mileage might be alot worse. Alot of highway, might not even notice.
