Are they the same trans bolt pattern? I'm wanting to swap out my 4.6 for a 5.0. the 5.0 is pretty much the same power as a lightning 5.4 and I know the 4.6 and 5.4 have the same bolt pattern but I was wondering seeing if because the lightning came with the 4r100 if the bolt pattern was different or not. I'm thinking I might use the 4r100 and mount it up to the 5.0.

 

I picked 2002 as a sample year. Ford lists part number XC3Z7005AA for the 4r100's tranny case for a 5.4L. They did not specify Lightning or not so 5.4L Lightning and regular F150 5.4L have the same tranny bolt pattern. But then you switched to 5.0L. Which one?

 

Sorry what I'm trying g to say is the 4.6, 5.0, and the 5.4 have the same bolt pattern for the transmission. But I was wondering if the lightning is different because it uses the 4r100 or if it was the same as a standard 5.4 because I would like to use the 4r100 on the coyote 5.0 because they are a awesome strong transmission.

 

Modular V8 pattern

• 4.6L SOHC/DOHC V8 (later castings, F3VE and up)
• 5.0L Coyote DOHC V8
• 5.4L SOHC/DOHC V8
• 6.0L Navistar Power Stroke DI turbodiesel V8 [5R110 Automatic Only]
• 6.2L Boss SOHC V8
• 6.4L Navistar Power Stroke DI twin-turbo diesel V8 [5R110 Automatic Only]
• 6.7L "Scorpion" Ford Power Stroke DI turbo diesel V8
• 6.8L Triton SOHC V10

 

Whether the bolt pattern lines up or not aint gonna be the problem. Running the trans is gonna be the problem.

I'd hazard a guess whatever system they have that communicates with the trans in the new 5.0 and tells it what to do and when to do it, aint gonna be compatible with the 4R100.

I shouldn't be guessing.

All 5.4L have the same bolt pattern, Lightning or not. The Lightning 4R100 has a 5.4L case with diesel internal parts.

He will probably need an aftermarket trans controller.

 

Thanks, Mark.

That's why I shouldn't be hazarding guesses. Let the pro's advise.

I've got same problem with truck I bought.
1991 f150 extended cab. It has a 5.4 in it . since research ing it so far ppl say that it had to be a motor swap...?

 

What’s the question?

Certainly, if your truck is sporting a Triton 5.4, it’s not factory issued. The f150 v8 options that year were the 5.0 and 5.8.

Otherwise, it’s not uncommon for someone not versed on their cubic inch to liter conversions to call a 351 a 5.4 when it actually is a 5.8 (or a 5.4 a 351 when it is actually a 330).
