Hi! I'm in the process to change the engine of my 2010 F150 5.4 3V 4X4 (135,000 miles) with an engine from a 2011 Expedition 5.4L 3V. 4X2 As the donor only has 38,000 miles, I'm wondering if it's a good idea to replace motor and transmission. Do you know if the transmission is plug and play with no PCM reprogramming?

Please note my truck has a 4X4 and the Expedition it's RWD I don't know if it matters, one mechanic told me the transmissions are the same but some endings are different.

My transmission it's a 6R80 Automatic and the Expedition also it's a 6R80 Donor's Expedition has VIN 1FMJU1K58BEF04255 and mine it's 1FTFX1EV0AKE67795 I already run the vin decode www.ford-trucks.com/forums/vindecoder.php and it appears as the 2 6R80 are the same with the exact same gears relation.

 

Hi artgarcia - since your question involves two different vehicles, it will probably get better responses in the Transmission forum.

Hi JackandJanet! You are right I may get better responses here. Thanks!

 

I see in the other thread the Expedition is a 4x2? If so, the transmission will not fit in your 4x4.

 

That's correct. I missed the 4x4 and 4x2 part. I wasn't sure about what else might be involved so I didn't reply, but that's a swap killer and makes it a no go.
