Wow, thanks for posting this stuff. It's going to help a lot of other people I'm sure. I'm planning on putting in a new torque converter in a few months. Now I know more about what to look out for. Thanks

Just as an "oh, by the way". Most vacuum modulators won't take 6 turns from the factory setting. About 3 either way is max. Much over that and it'll either lock up, or pop the diaphragm. And that came from one of the tech instructors at GM.

Thanks for the tip on the modulator.
I chose the Jegs solely on budget due to having a new baby, and not as much money to spend on toys
I actually now will be replacing the governor next because WOT is no longer wanting to shift from 2nd to 3rd once the car heats up (20-30 mins of driving) If I let off the gas it shifts fine

I am happy with the way the car is driving with the new converter, it seems to help get it off the line better.
I don't know exactly how to test it but the car will rev to about 1500RPM without really seeming to engage much, then it starts pulling through the brakes at about 2000-2100 RPM.
There seems to be more "Oomph" / Throws you back in your seat with hard acceleration and drives normally under slower acceleration.
Hope this helps everyone!
