I have access to SCT ADVIII Software/Tuners
I have access to a 2005 5R55E Sport Trac PCM RVB0 (Running vehicle).
Questions:
Is the difference from 4R to 5R hardware, coding or both? Both
Would a 4R wired to a 5R PCM work as a 5sp? Yes, just not optimized
Would a 4R coded with 5R scalars work as a 5sp? Yes
Could a 4R PCM be upgraded to control a 5R when installing a 5R transmission? Yes
Would the 4R do better with a 5R Valvebody and the proper PCM? Valvebody - probably; Trans - yes; PCM - no needed, just the Scalars.
Step 1 will be the Trans Coding per the PCM.
Will post this evening.
[Edit]
Transmission "Switches" did NOT work, 4R44E and 5R55E switch settings in the PCM are identical.
The Transmission "Scalars" has to be copied as the values needed can not be modified, only replaced.
