Whether or not your particular truck performs as per the FSM is irrelevant, what is relevant is your claim that the operation of your transmission is in accordance with the FSM.
All of the lines of rhetoric boil down to these simple facts:
FACT #1 My original post reads: "if the OD switch is in the ON position the converter won't lockup until after the 3-4 upshift." to which you replied with the following: " FSM and my truck disagree with both Kunkle (sic) and the Marsh Mellow". So, what you're saying there is that the lockup doesn't depend on the switch position and the FSM agrees with you but anybody who can read and comprehend the English language will see by the text in my provided link that (regardless of sensor input) the lockup DOES ultimately depend on the control switch and, therefore, the FSM is totally contradictory to your claim.
By clearly stating that the FSM supports your contention, you got caught again in your own bullshit and then spent a thousand words trying to spin in your favor the fact that you did get caught.
FACT #2 In your original post on this thread you clearly stated: "Next, the shift into OD means the TC unlocks briefly" and when challenged by me for backup you clearly stated: "Try actually reading the technical bulletins and you'll see exactly what I'm talking about."
So, again you claim that the TC unlocks at the shift and that this is normal operation and that "technical bulletins" will back you up but when actually pressed for a reference to back it up you provide a link to a TSB describing a fault which is not normal operation. Again you got caught in your own bullshit and spent more words trying to backspin that.
In the end, bullshit is your stock and trade.
If you want to continue to make statements about the operation of an automatic transmission you would be wise to make the statements without claiming to have backup tech references that don't exist or totally refute your claims.
