Hi from Australia.

[Bazza]

I have blown a head gasket and might have the chance to change the motor at the same time. Tribeca 3.0 to 3.6 Thanks for any help re any different items required ie computer or other components. Barry.

Far too much work with wiring harnesses, PCM, TCM, Body Control and key programming.
Not worth the effort, have the heads rebuilt by an expert or get the exact replacement ie:
