    ...anone that has done an engine swap. This will be my mechanic's first hybrid engine swap. Any links would be appreciated.

    the mechanical components are on the left and the electrical components are on the right side, so they aren't intermingled together. if your mechanic has done any engine swap before, they should be able to take care of it, no problems.

    That's where they are if you're standing in front of the car, facing it. Which is reasonable enough, but don't forget that shop manuals are normally written with left and right meaning when facing the same way the car is, putting the engine on the right, and the hybrid tranny on the left.

    Anyway, in the official procedure (I think still in Gen 3), engine and tranny drop out together, then can be separated in the shop, tranny mounted on new engine, then both reinstalled in the car.

    I think I've seen some DIY reports of successfully separating them in the engine bay so just one or the other can be dropped out, but the space for doing that is tight.

    The shop manuals are at techinfo.toyota.com and as long as the mechanic follows them carefully, I wouldn't expect any trouble.

    Not that I recommend it, but it may be possible to replace the engine with the transaxle still attached.

    See this video of Carolyn at Luscious Garage replacing MG2 on a Gen1. She didn't pull the entire engine/transmission.

    You can easily drop the engine without the transaxle attached. Not so easy dropping the transaxle.
