I wanted to bring this one back from the dead since I am still in search of knowledge when it comes to torque converters. Grant it t.c. aren't cool and it isn't something you build in your garage. But what they do and how they do is way cool in my book so I have been trying to following what's out there as far as how they are made and what parts go in them. This is the lastest newsletter I have gotten. It might be a good read for those who might be interested.

It also sounds like you have other issues going on too with the 2/3 shift. I suggest starting a new thread to address these issues. You'll get more input that way since this thread is more of a theory of TC build and design weakness.

CampSpringsJohn: I looked at slim613's avatar too, I am pretty sure it says "Rope her" in keeping with the logo. Regardless, it it could be considered misognistic and he may want to consider changing it unless he is ok with that reflection on him.
On the other hand I totally approve of FordPride's and Pitcrw6's avatars...

Tim, you are right. My eyes aren't as good as they used to be. I apologize to slim613.
As for the other avatars you mention, I agree!

I'm sorry to hear you are having problems. Personally I think your issues with the TC are in the pump. That is just my guess. There are 4 components that effect the TC lock up: PCM, solenoid pack, pump valves/PWM valve & drain valve and the TC. Now you said "CHIP" have tried with stock pcm tune?

the only other issue i have is the TC and yes i have removed my php hydra chip and just ran stock no tuning at all i thought it was that and removed it and it still does it so then i swaped PCM's that didnt work either

How did you check the harness?
That's as useful as rotating the tires. It has no bearing on this problem.
I'm leaning towards an engine problem.

This tells me it is an engine problem, not a converter problem. Why do you think it is a torque converter problem?
How did you check the harness?
How do you know they are good? I've seen several people assume that things are good and then can't diagnose what's wrong because the "know" these things are good.

What valve are you leaning towards?

I didn't caught that but either way it may read I do not approve of it. I too have a wife & daughter and was brought up to respect woman. One the reasons I like FTE is the liked minded family type place I like to go. My 6 yr old daughter actually read posts here on FTE because this is a place I feel safe with her. So all I ask is that he rethink the whole joke because I don't appreciate it either.
