Is this the right fluid for my vehicle?

It is ATF+4, the spec for most Chrysler, Dodge, Jeep and Ram automatic transmissions from the late 1990s onward. Check your owner's manual: some newer models use a different fluid such as ATF+4-only or 8/9-speed fluid.

How much do I need for a fluid change?

It depends on the transmission. A pan drop typically takes 4 to 6 quarts, while a full flush can take 10 or more. Buy by the quart and check your service manual for the fill capacity.

Can I mix it with other ATF+4 brands?

Yes. Any fluid labeled ATF+4 is licensed to the same specification, so topping off with another licensed ATF+4 brand is acceptable. Avoid multi-vehicle fluids that only claim ATF+4 compatibility.

Is it different from ATF+3 or ATF+4 from other brands?

ATF+4 replaced ATF+3 and is not interchangeable with it in transmissions that require ATF+4. Licensed aftermarket ATF+4 meets the same spec, so the difference is mainly the bottle and the price.

Does it come in a larger container?

Mopar sells ATF+4 in quart bottles and larger jugs under different part numbers. This part number is the quart bottle, so a full service usually means buying several.
