With the VB looking good, EPC Ohming good, I got to wondering...
If the Lead Frame Ohms good, it could be a bad wire between the PCM and the trans.
That harness passes between the engine and the firewall, during the collision the engine could have moved in the mounts enough to pinch the harness...
All 4 OEM Ford servos Ohmed in spec (code was EPC Fail).
No indications of blow outs or leaks.
Have to Ohm the lead frame...
2-3 piston dropped out with VB, piston cover worn from rubbing on the plate.
Is that cover in the 2-3 area designed to keep the separator plate from being...
Just trying to "tighten up" the stock 4R70W - We'll run it until it breaks, then upgrade as needed.
This is for towing a 5,000lb trailer with a mostly stock 5.0L (Headers, MF Cats) once transplanted in the Sport Trac.
But I will be sure to look back here when I need to!
I really appreciate all...
Been tuning with SCT since 2005, and I can confirm.
I prefer to service trans (Fluid, Filter, Bands adjusted - if possible, replace the EPC/TCC/Shift solenoids), beef the VB, then tune.
My 5R55E went for 80K+ this way until the factory TC (with 178K+) decided it was done playing. Now it gets...

No hole names though - you have to bounce back and forth from the text.
Updates: There was no yellow "Plunger" in the pan, filter was reasonably clean suggesting service on the trans in the past.
From Superior regarding their "Supertuff" 4R70W 4R75 Ford Valve Body Plate Kit K092/K0192:
"If you use the .092 it gives you a firmer 1-2 shift. If you want a factory shift use the K0-192"
So the 2000 can use the "Supertuff" plate.
The K092 has a .092” 1-2 Feed Hole (hence the name?) for...
No rebuild (I hope).
Is the Sonnax VB upgrade $75 in addition to the Sonnax ZipKit?
I'll take a deeper dive on their page.
Having done a couple 5R55E's, an A4LD and a couple 6R80's, I'm sold on the Sonnax stuff...
ReKey Ignition and doors to match
I was given one key - going to use FORscan to edit once "S" (40bit keys) arrive.
4R70W codes and flashing O/D light
No debris in pan, suspect bad Internal Molded Lead-Frame (plastic harness) or failed EPC Solenoid.
As the title suggests...
Not Another Explorer 5.0L To Sport Trac Swap Thread...
