Comin home lastnight and tromped on the gas in level 3 a couple times and truck went limp and thru codes P0777 and 0700. I couldnt clear with the edge so I took it this morning to tranny guys that did my jr kit. They got the codes to clear and said to back off on power level and see if it throw the codes again. Tranny felt normal after they test drove. I was under the impression that with transgo jr I wouldnt have any probs in level 3. Now its got me worried to put my foot into again. Anybody have same prob or got any insight?
I know the tranny is not shot cause its shifting fine.

Do you know by experience?
He is Mike L. He know's everything about the Allison
What is the edge rate on level 4? I don't have one so idk....
Oh well with a transgo i would think it would be fine. I have run several hotter tunes than that and been fine. I did however limp my trans like last week. Im about to hit tyler up and order a transparts stage IV shift kit i think
