An engine replacement these days is very expensive compared to what it cost in the past. Even used engines are expensive, used to buy a couple cars for the cost of an engine alone. Ken shows the book numbers. Those don't include any parts mark-up or all the ancillary items like fluids, refrigerant and the like. Plus that is a JATCO made CVT equipped vehicle and those don't have a stellar reputation themselves. You might get a better price if you go to an independent shop and get a remanufactured engine like a Jasper or similar.

I've found a few used engines with low mileage for decent prices. I'm more interested in the rates for labor. What is a fair price?

Labor rates vary a lot. Location is a big factor, as is the cost of living in that area. Currently my shop rate is $100.00 per hour. billed in 1/2-hour increments. However, there are shops around me at $120.00 and $160.00 plus I know of shops in the more urban areas that are in the $200.00 range. The trick is finding a shop that you trust and do good work. Also be advised that if you source the engine yourself it falls back on you if that engine has a problem. So say you pay the shop to swap the engine you supplied and as soon as it's started it is knocking or using oil, you will be the one to deal with the yard over getting a replacement and you will pay the shop the same amount to remove the bad one and install the next one.
That is why I would also price out a remanufactured through a shop as well. If the remanufactured is $1,100.00 more but you get a warranty and at least part or all of the labor covered in the event of a warranty claim it can be lower cost in the long run. That would be your call to make.
