Question edited for clarity and typo, and add maker. Question moved to model category. The AC evaporator core and the heating core are normally two separate items.

I usually drive the old one into the block with a long, blunt punch, turn it sideways and pry it out. I coat the edge of the new one with Permatex sealer and drive it in with a driver that's just a little bit smaller than the cup of the new plug. A socket on the end of an extension works in a pinch.

You can buy small adapters that you plug into the car harness connector and allows you to test that the power is being supplied correctly. In your case, I would suspect that the trailer wiring is at fault, rather than the truck's wiring.. https://www.google.com/search?q=trailer+7+way+plug+tester .

Question edited for clarity. Full year make model in title and mis-spelling of 'misfire'. Question moved to sub category. The misfire code only tell you that, unfortunately it doesn't tell you why. When swapping parts to test theories, only swap one thing, one cylinder to one cylinder and only one item, the coil, the plug or the wires, not all three. What was the make of the Crankshaft Sensor? Only buy quality OEM replacements as there is a history of bad ones from Mexico and China. Wouldn't hurt to check the wires again.

Sounds like you have a serious vacum leak.; DTC 0174 and 0174 are lean conditions on bank 1 and bank 2, 0300 is random misfire. The only thing I can think of is a big vacum leak like the brake booster / vac line leaking, or maybe the intake manifold is cracked ... even a stuck-open EGR doesn't normally lean a motor that much. Start by checking for a vacum leak, if the motor will idle you can spray a little WD-40 around ports and lines >> if the idle speeds up or becomes smooth you on the right track in the area you judt sprayed.

Very likely that the 3-4 clutch pack piston seal has blown out. Will need to be taken apart and repaired before too much damage occurs. Drive it in manual 2 to get where you are going. Do NOT put it in 3 or OD and do not let it try to go into 3rd again until it is rebuilt. Sorry for the bad news. This is a common problem.
