No I haven't looked very close. They may interchange? I think the cvt coolers have a different part number too? It'd suck to find out the hard way that they don't though interchagne. I would try it on my own or experiment on someones car for next to nothing just to find out.
I've installed transmissions in gm's that had different part numbers and gm said they were different but they interchanged with other years just fine. If I get a chance I'll check out the plugs and try to see the wiring colors to see if they both match up on mine to the 15's. I wonder who at mitsubishi would know what changed? I'm sure nobody at any dealership would have the faintest idea.
If mine blows I'll likely order up a used 15' and give it a go. I wouldn't pay someone to try it thought.
And $1300 labour? Seems a little steep but better than renting a shop with a hoist, buying tools and learning how to do it yourself taking up to a week.
