Trans gasket/filter replacement

I recently had some work done to my care and believe they may have messed something up. my cars trans was completely flushed and then they said I need a new trans gasket and filter. The car now leaks trans fluid, which it didn't do before I took it there. Can I just have my gasket and filter replaced and use the same brand new fluid already in my car? If so, what would that cost? Thanks!!

How would i know if my fuses have been switched? A friend of mine’s ex boyfriend

A friend of mine's ex boyfriend messed with her fuse box and we can't figure out what's wrong. She believes he switched some of them and possibly took a few but we can't figure it out the manuals aren't color-coded or say anything specific about the chips and where they should be placed. Please help!
