You can use the 4 speed with the 3.5. Thats whats in mine. I think its the later model 3.5 that came with the 5 speed

You can use that trans, but I'm pretty sure there's gonna be alot more to it than just swapping the motor.

Yea youre going to need a new pcm and probably motor mounts at least. Im not sure about rear diff, axles, or front suspension though.

I did some looking around and found that the 2.7 and 3.5 share many of the same parts. The 3.5 should drop right in. There may be a few minor components to update or change but the PCM and wiring harness should work too. If both engines used the same transmission, tuning/programming may be all that's needed. I'm not someone to provide the details on this. The information is out there.

------Ross (greenking) may have more information on this.
