2007 4.0 engine and tranny swap into a 98

[kiragyu]

hey guys i was wondering i found a 2007 4.0 engine and tranny to swap into my 98 3.0 truck. my question is will the motor and tranny be the same length as my engine and tranny now? and also will i need the pcm out of that truck or will i be able to flash the pcm that is in the truck now and have it work?

Motor and tranny should both bolt up. You will need the new ecu
