You'll get tired of watching some guy collect $150/hr to take out four screws, detatch 3 or 4 wires and attach them to the new thing.

One bolt, drain into pan, pour in new fluid.

You'll find YouTube and watch some videos and realize this **** is so easy you have no idea why you kept paying people do such basic stuff.

Or you'll get used to paying it.
