TRNW-2: 42rle never goes past partial lockup

[Steve Everett]

I have an 05 Dakota with 42rle that I'm trying to solve this lockup issue,
built by someone else , and has not been delivered to the customer yet,
originally it was kicking in and out of partial lockup randomly,  after
driving it a couple times we decided to unplug the alternator as it had
recently been replaced,   that stopped the in and out of lockup,  installed
a new alternator, no more in and out of lockup issues,  but it never goes
into full lockup , no matter what speed , driving on level ground ,
50-60mph,  stays in partial lockup and we can feel and hear the lockup
groaning,   desired matches actual lockup apply on the scanner,  its like
the computer isn't telling it , or letting it go to full lockup ?

    I had them pull the valvebody and I checked it over, all checkballs
correct,  solenoid switch valves replaced using the transgo valves,  new
dealer solenoid assembly,   I'm kind of at a loss on this one,  I wanted to
replace the tcc reg valve, but the only option is a Sonnax oversize and I
don't have access to the reamer for that

  This post from years ago describes exactly what this one is doing,  but
there are no tsb's that apply to this vehicle
