okay. i was looking at a 2007 Altima Sedan 2.5 S and it says pick a transmission.. it doesnt have automic but it has Xtronic CVT (Continuously Variable Transmission) and i was wondering what that meant??

For all intends and purposes, you may regard CVT as an advanced automatic transmission.
But rather than having "steps" of "definite gears" (ie; 1, 2, 3, 4, 5) it glides through all these "steplessly". So you won't feel the gearchange jolt.
CVT is the most efficient automatic you can buy because it can "fix" the engine speed at it's most efficient point as the car increases in speed. Go test drive one, it's pretty cool to see the speedo climbing with the SAME engine rpm!

is a transmission in which the ratio of the rotational speeds of two shafts, as the input shaft and output shaft of a vehicle or other machine, can be varied continuously within a given range, providing an infinite number of possible ratios.
The continuously variable transmission should not be confused with the power split transmission (PST), as used in the Toyota Prius and other hybrid vehicles that use two or more inputs with one output, despite some similarities in their function.
A CVT need not be automatic, nor include zero or reverse output. Such features may be adapted to CVTs in certain specific applications.
Other mechanical transmissions only allow a few different discrete gear ratios to be selected, but the continuously variable transmission essentially has an infinite number of ratios available within a finite range, so it enables the relationship between the speed of a vehicle engine and the driven speed of the wheels to be selected within a continuous range. This can provide better fuel economy than other transmissions by enabling the engine to run at its most efficient speeds within a narrow range.
CVT transmissions have been refined over the years and are much improved from their origins.

cvts have computer-controlled adjustable gear ratios
