Cummins 2005 some jerking from tranny
7130, 9 05r, Dodge 2005 3500 Cummins, Double chipped, Predator 100 hp power performamce and the Diablo, I just had my Trannny serviced and they said everything is great, even though I pull a 16,000 lb Toyhauler. I downloaded the last 2 upgrades to the predator and it seems that going down hills it jerks in and out of overdrive, they told me to turn it down a little on power i did and it still does it unless I go back to stock. ANY SUGGESTIONS WOULD BE APRREACIATED.

try options/troubleshooting/restore original backup, then reload the tune.

RE: Cummins 2005 some jerking from tranny
I am not sure but do not think that is your tc. kicking in and out. I have a tc lock switch and have locked it and still get that bit of a surge going down hill. with mine it usually happens for a bit just as I take my foot out of it. I think its just a case of the engine burning off the fuel that is the rail. Does you truck hang if you rev it up in neutral? and come back to idle slowly and in stages?

Not really,It revs up but comes back down. It just started with the r9.03 program. It is when you start to coast, But not with the original program.
RE: Cummins 2005 some jerking from tranny
well I think it still has to do with the extra presure from the tunes, that fuel has to go somewhere, hope so anyway I really hate the other option of injectors junk

RE: Cummins 2005 some jerking from tranny
I still don't know what is causing my tranny jerking in and out, only when I let off the pedal. The tranny guy told me to turn it down and see what happens, The original tune works great but any program it jerks. Anyone else still having the problem?
RE: Cummins 2005 some jerking from tranny
If you floor the throttle when in park and release does your truck come down to a nice idle or does it come down slowly in steps? Mine comes down very slowly and jerky when I have a tune on. Does it a bit without a tune. I think this might be the same issue that I see when letting off the throttle going down hill. If I can swing it this year I want to replace my injectors which might shed some truth to those that tell me that is the problem.
