I bought my truck about a month ago. When I bought it, it was heavily modified. I do not know every mod on it yet, but I am having issues with the tranny slipping sometimes and it throws a code. It doesn't have the problem all the time. It seems to happen mostly when I turn the programmer up to the extreme setting or into the race setting. The code would say that overdrive is slipping, so I turned off the overdrive while in either race or extreme setting, but it still throws a code and slips. When the code throws, it acts really weird. Some info would be appreciated! It has the Edge juice attitude programmer in it.
Tranny issue?

Sounds like the trans is just about dead. Put the tuning back to stock and start saving your money.
Does heavily modified include a built tranny or not? Def sounds like your tranny is giving out and you need to ditch the edge...
Heavily modified, slipping trans and edge don't belong in the same post... Your trans is probably done for because of the edge and yours/the PO's driving habits. Time to save some money and get it built!
Here is the kicker, the truck only has 37,700 miles on it.
As for modifications I know, 4" exhaust, aftermarket turbo, bigger injectors, air intake, edge power programmer. That is all the performance upgrades I could notice or have receipts for on the truck. The truck is lifted 8" with a CST lift, has 22.5" Alcoa semi truck wheels, aftermarket driveline, aftermarket rear end, wildwood break system, and sure there is more. There is a lot more mods then I have listed. I am just worried about the tranny right now. It's in the shop, so I will find out for sure today

Almost everything you listed there is detrimental to the trans. 37,000 miles was a good run for it haha
I usually drive around in "mileage" mode or "drive" mode and it doesn't seem to have a problem in those modes. I think it slipped once or twice in "drive" mode (which is 3rd stage). I unfortunately did not buy the extended warranty due to the truck only having 32,700 miles on it when I bought it! Damn it, I thought these Allison's were supposed to be bullet proof?!?
Nothing will heal your trans, it needs to be built. Drive it easy and save your money for a trans. And throw away the Edge.
3K in parts for a good kit. if you can do it yourself and save the money. otherwise it will run 4500-5K. worth it though to put power to the ground.
How important is power to you? If it is get EFI Live tuning for it and have your transmission built by someone REPUTABLE. The Trans will cost you right around 4k + or - depending on parts/kit you want. DITCH THE EDGE!
If power ain't important to you rebuild it stock, use stock tune and have an Allison that will last a long time.

not that bad just heavy like 450lbs heavy. convertor bolts are the hardest thing to get to. where are you located?
Its called "limping the trans". It usually starts with the 4-5 shift and progressively gets worse. Put the truck back to stock tuning until you can rebuild the trans.
