So I pulled the 4.6 and all indications were that it would be fine to mate an 03 Lightning motor with the existing drive train.
Literally, hundreds of hours later, I have a running truck...again! However, there are "issues" that I am in need of help to overcome.
1st: I changed to an 03 computer
2nd: Motor from 03 Lightning
3rd: SVT Cluster from 03
4th: PATS and EGR bypass
5th: C&L Intake
6th: AcuFab single blade TB
7th: 91mm Mass-air (stock I think)
8th: 4lb Lower pulley
9th: T-rex external pump
10th: Electric fans
11th: SCT Flash
So, without the flash, truck will not start due to PATS. However, the "stock" tune in the SCT corrected that with the PATS bypass. It starts, runs, idles. Life is nice. If I try and drive it though, life is not so nice.
In "P", the truck is parked. R=reverse. "D" is 2nd. The truck starts in 2nd and never shifts. 2nd is first, and the truck will shift from 1st to 2nd if I shift up or down from there (manaully pulling the lever). 1st is first and will shift to second (manually) but never into drive...manual or otherwise
From what I have been able to decifer, the trans from the 4.6 has a different "value" on the communication side...ultimately meaning....I need for someone to modify the code in the ecu or I need a stand-alone computer for the trans...before I can get it to perform properly.
Now, on a lighter note, there is no speed indicator (wheel or drive line) from the old 4.6 setup. Shift pattern (as I have been told) worked off of a combination of vac and spark.
Any input? Please! Oh, two other issues but the are separate threads....take a look.
Is the trans in the truck a 4R100 or 4R70? If it's the 70 you should probably be looking to upgrade anyway. I think the two use different control strategies and that would be where your problem is if that's the case.
I called Mike.....hell of a guy....just wish we were in closer proximity to each other.
He was able to answer my questions.....not that I wanted to hear them! Art Carr was mistaken when they said the swap would be a simple r&r. None of this would bother me at all if I had more time, but this thing has to be ready to to the day after Christmas and EVERYONE gets a case of dead-*** in December.......
BTS is definitely the way to go if you're looking for a rebuilt trans. I though you wanted a junkyard trans to swap in. Art Carr couldn't pay me to use their stuff; I've heard too many nightmares. The swap from a 4R70 to a 4R100 should be very close to a direct bolt in, but you may need some other parts from a 4wd F-150 to make it a true bolt in.
