I need some brainstorming on a problem

I have a 1999 dodge it has quadzill adrenaline, and fass fuel pump. The valve body is high pressure and it has a georand torque convertor. My problem is that my torque convertor is jumping in and out. This only happens when I am driving at a steady speed down the highway. It doesnt happen when I am accelerating or when i have my manual lock in switch on. the trans temp is always under 150 as well. When i changed my oil last week i disconnected the batteries and when I hooked everything back up everything worked fine for a two weeks. Today it started jumping again so I just used my manual switch on the way home tonight. I have a hard time believing that it is shot if it "fixed itself" for two weeks. Please just throw out any ideas that you might think of.......please help me haha thank you.......................bob

1999 2500 24v cummins..... built vp44 with fass fuel system with oversized lines, quadzilla adrenaline, built auto and convertor, 5 inch to 6 inch stacks, intake.

1994 dodge 12v cummins...(my project truck) Built auto with shift kit, afe intake, marine 370s,#0 plate, afc forward.

Here is how you tune it:

But what i would do is call goerend first, to make sure im not telling you anything wrong and goerend number is (563)-778-2719

Timbo Apps might be a better choice than hacking up the wiring and adding on a bunch of stuff...

Typically the problem is the carbon track wears out making it very unstable for the voltage hence lock and unlock the TQ conv. I found if you replace with a Timbo the problem is over...



No crazy voltage calibrations to do... It just works...

I look at it this way the truck work all these years without the hack and modification why do it need it now? It don't the fact is something is wore out and needs to be replaced... Don't cover up a problem with a hack or wiring mod...
