You probably found this stuff already. But here it is.
The tranny work is messy, any parts store will have the parts, you will need a torque wrench, and the U-bend needs to be removed by a shop.
But you can handle the rest easy enough plus your regular maintenance
Taylor wires are good quality for a good price.
You will learn that 3800 exhausts usually sound like crap no matter what.
Good luck.
