yeah...you're both missing that it is supposedly an 1987 - 2000 issue...

 

My 2000 never locked at wot when it was stock.

 

logged?

 

Nope, but it's pretty obvious when a converter locks up.

 

not @ wot w/ a stock converter

 

Hmm...very interesting. Lots of reading between two threads. Long story short, if you have an 87 to '00, update your pcm or get the fix from ed or any custom tuner.

No offense to anybody but, at WOT +75mph in a low 12sec truck, I almost cant tell that mine locks. If it was stock, no way. Imagine doing a 11.5 or 10 sec run, you'd never know unless you have a PI like Ky.

 

I think the faster you go the easier it is to feel the converter lock, but maybe that is just mine, before the trans rebuild my line pressure goes up to aid in the tcc lock which makes mine a bit more firm. Now I actually have a modified tcc valve. it locks so hard now it jars the truck. I know when it locks at any speed. But I could see a stock on going undetected. None the less. now that I actually understand what the whole thread is about Like Dew said, a simple upgrade to an 01-02 pcm would be the best/easiest fix.

 

80e?

I didnt look at my tune or anything, I think my tcc tables are a stock segment anyway. But I didnt know my big *** verter was locking at WOT>

 

TTT. My 80e swap in my camaro does this. Anyone know of a fix yet?

 

well...
I used the new adjusted tune after completing segment swaps of each section...
still locks in 2nd and 3rd...
going to try it again with segment swaps on everything EXCEPT transmission sections...then copy & paste on transmission tables...
If that doesn't work...then I'll try it w/o segment swaps and doing table by table conversions...
we'll see...
