few tips:
get a quart or 2 of transmission fluid, you'll need to refill some after.
if you jack up the driver side and let it rest on jacks stands - let it lean to passenger, you'll have less transmission fluid leak when you remove the transmission case side lines (remove transmission case lines last)
pay attention to how the c-clips are on before you remove them. you'll need to put them on the same direction to keep the line locked in and the plastic security cap to fit properly
remove the front line clips 1st - make sure you do it slow and try to keep an eye or your hand over the c-cliip - they will fly off and are hard to find. i tucked an old towel under and around after losing the 1st one
when removing the clips on the transmission lay papers or spill mat, you will still get some trans fluid leaking out. again keep an eye on the direction of the c-clips and don't let them fly off
before you remove the lines completely pay attention to how it is in reference to the other existing lines, especially in the front. push the lines as far forward as you need to clear the rear of the transmission end lines then you can drop it a bit and pull the whole assembly out towards the back. snake the new lines in reverse.
put the c-clips back in until they are seated, the plastic lock cover should fit as is was when you removed it.
it's not that hard just be methodical and it'll take about 30 minutes
