I've been lurking around for a while and finnaly joined... I've got a 99 z24 with a 4 speed auto.. its cracked..

i got a used tranny at a junk yard.....anyway i need to put it in now.. instead of paying someone 250 to put it in for me i wanna do it myself.. I've helped replace a 3speed in a 2 door 2.2 but never anything with the 4 speed 2.4... anyone know of a walkthrew or soemthing? somethign i can read and do what it says lol.... I've got a haynes manual but its really hazy when it comes to the 4 speed...any help would be greatly appreciated..

I've been looking around in a few places and it looks like a good bit of work.. like i said i helped change the 3 speed.. but i'm not expert by any means.. is it worth 250 to let someone else do it... or should i save my self 250?
