No it's not worth the work, and no the trans won't bolt-up.
To swap the motor is easy. Yes, the transmission will not bolt up. You will need to swap more than the engine. You will need the engine wire harness, ECU, etc.first off, is it worth it? my 3.0l v6 headgasket is gone but still runs great(not for long) my 4runner is a 5spd manual and i do have 2 spare 22re motors, would the 22re bolt onto this transmission?

OK, if the engine won't bolt to the trans, and the motor mounts, cooling, exhaust, ECU, and wiring need to be changed, how is it easy ??
