Ok... i came up with a '98 5.4. It has an oil accumulator on it. my 97 4.6 does not. Do i have to use this or not?

 

i have a question my buddy did the engine swap got the 5.4 out of a 98 expedition and put it into his 97 f150 put it to coil packs instead of the coil on plug motor ran fine but blew tranys so we put the E4OD in it bolted up fine had to make a new crossmember and driveshaft but is in fine now the harness is where were missing something.

the harness for the pcm out of the expedition plugs right in to the old one but when started the truck shifts fine manually but if put in drive it starts in third.

the trouble code pulled is a P0707 trans range sensor malfunction. we chased all the wires from the 4.6 harness to the 5.4 harness all are the same except the trs plug and speed sensor plug there is also 4 extra wires on the 5.4 harness we dont know where they go or what pin they belong in any help is greatly appreciated.

 

JMC, I am also thinking of doing the 5.4 swap. Your sig says that you have the M5OD so i was curious if that bolted right up or did you have to use an adapter plate to make it work? Also i thought the M5OD was only a 2wd trans? Could anyone clear that up for me. Thanks for any help

 

There are 4 versions of the M5OD-R2.
1) 4.2 V6 4x2
2) 4.2 V6 4x4
3) 4.6 V8 4x2
4) 4.6 V8 4x4

All the 4.6 and 5.4 blocks have the same bell housing bolt configuration. The 4.2 is different.

I was sent here by some guys from another forum. I understand that the 99 5.4 is by far the most solid engine to use. My question is what would it take to swap it into a 2003 F150 FX4? The truck presently is running the 4.6 windsor thats on its last leg. All I know about the engine is it is running COD ignition. Is the 99 COD or coil pack?

Thanks in advance.

Basically remove the 4.6 and bolt in the 5.4.

 

what do you think about using a 03 5.4 out of a f250.. i already have the motor in and the 5spd will not go in gear while the truck is running.. also i have some oil pan clearness issues any suggestion on that.. i used a 8 bolt flywheel and a cluch for the 4.6 they matched up perfect.. thats for any help!!!!!!

Bleed the clutch.

i have figured it out. i had ordered a 8 bolt flywheel and clutch for the 4.6 and recieved every thing for a 2001 F250..... reordered every thing should have it all by tomorrow!!!! hope it all work this time....

thanks joe

 

That makes sense. Wrong clutch. Glad to see you are on top of the situation. Sucks that you have to install it all over again.

my flywheel did not show up i will have to wait another week till i get to work on it...

 

I just did a 5.4 swap into a 97 f-150, using an engine from a 2000 e-150 van. I have everything hooked up but the exhaust. But it cranks but doesn't start. I have spark out of the 4.6 coil packs but it still doesn't start. I used the 4.6 harness and the 5.4 computer. should I use the 4.6 computer? Its been an interesting swap since the exhaust manifold and egr tube and throttle body housing is different from a van to a truck. Once that was sorted out now it won't start. Any help would be appreciated. Thanks in advance.

 

Use the 4.6 PCM. The 5.4 uses PATS and I am sure the Connector Pin Outs are the different. The 5.4 uses COP Ignition and your 4.6 uses coil pack. Click on the link to my notes at the bottom of my sig.

Ok, thanks. I know some of the pins are different. I just wasn't sure how well it would run with the 4.6 software. BTW your notes were quite helpful during the swap I just wasn't sure on a few details. Thanks

 

Hey just wanted to let you know, turns out the injector plugs were slightly different. I switched all the injectors from the 4.6 into the 5.4 and it started right up and ran good. Thanks for your help.
