2002 sentra transmisson

[synergy]

Well since my transmission went i need to find a new one. Anyone know of a good place to get one or anyone have one. I know this may seem like the wrong section but almost nobody sells sentra parts in the engine drivetrain area and also im looking for maybe a reman transmission or engine and transmission?

Thanks.

P.S how hard is a FF transmisson change i know need to take out a half axle and yata yata but how difficult is it once im actualy in there?
