Default got a TC lock prob. help

I have tried all I can think of with edit.. At the 3-4 shift the TC unlocks for a second, then shifts, then locks up again.. This is just cruising around. It didn't do it a while ago, now even with putting stock settings in it, still does it... Anyone, have an answer or what to check?

Same issue here...I remember someone asked the question a while back and got no answer (not from Ken Kelly either):
Why does pcm unlock TC during shift even though the option in Edit is set to TCC Lock during SHift = 1? (and of course all the unlock/lock values are set properly).

A misfire will cause your TC to unlock. Try eliminating misfire detection (only temprorarily if you would like) and see if the problem goes away.

Change Misfire detection temp to 155 and 154 respectively.

Only problem is , its ONLY unlocking the second before the 3-4 shift, then shifts, then re-locks..

Well the easy fix, which seems to drive fine is---
to just make the 3rd gear lock up later than the 4th. so it won't lock 3rd.. no biggie drives fine.
I actually have it shift to 3rd at say 30 then 4th at 35 then lock at 38.. the mph #'s are like 5-10 higher in edit than real life.. Takes some time and trial but works well, and doesn't **** me off now. Thats all that matters to me
