Ok so what's the story with these modified TC's that have higher stall speeds? I've read about TC's with higher stall speeds and lower stall speeds.

What's good for a Grand Cherokee?? And would these add any advantage great enough to make up for the cost?

Higher stall speeds are usually used in high horsepower vehicles w/ larger cam profiles, lumpy cam will make your stock converter drag, kinda like havin your clutch partially disengaged. A lower stall works nice with a RV/towing type cam, geared more for low end torque. I dont know your knowledge of vehicles so it is not easy for me to explain. Angelous should chime in, he's the tranny guy.(transmission that is)

simply put, the torque converter is like a clutch. the 42's and 46's have an 1800 stall from the factory. This means that at 1800 rpm the trans is lock-up ( clutch plates are fully engaged with no slip). It all depends on what you plan to use the vehicle for for instance if you offroad yours the lower stall will help in keep the trans. from slipping (less heat) and wearing out quickly. There are a lot of variables such as gears, horse power, tires, engine size (I-6 vs v8), etc....... What ever you do make sure that you get a quality converter. If the converter ever fails all the staters that get stripped out will be pushed into the trans. Be careful installing it as well because you can easily damage the pump.
