time for transmission fluid change need a little input from the fam..

[ralliartSAT]

so i'm in need of changing the transmission fluid and don't really want to take it to the stealership because their trying to charge me an arm and a leg(480-500).. i looked on the forums and it does not look hard(only hard part is the filter it said lol) i was just wondering if anyone knows where i can get the fluid and the filter and what kind of fluid would be best to use. also if i should do the oil change as well at the same time. i red i should but wanted some in put.

also im depending if i should take it to the stealership in case i have any problems with the transmission i can take it back because it'll be under warranty lol..

thanks ralliart friends!!!
