I got my Quadzilla stealth on Friday and decided to stack it with Edge Hot Juice set on four.Well on levels one and two the truck ran like it never did before.I thought if two was this much fun I'll try it set on four.The truck ripped through the first four gears but on the 4-5 shift it was like it was in neutral and the engine lost a bunch of power.I pulled into a parking lot and hooked up the quad tuner,cleared the code and unloaded the program.Did I hurt anything?The truck runs and drives fine but I still wonder if I damaged my tranny.

 

That is pretty much a safety feature so you should be fine.

 

So did you piggy-back the two?

 

Well, as far as long term damage I'm not sure. But as for what was going on --- too much power. The stock Allison is only good upto 400-450 hp at the flywheel, when you go over that the overdrive clutchs start to slip. Go to atsdiesel.com and read up on the transmission basics of the allison and look into some of their performance upgrades before you do that again!
