This is going to be really hard to describe, but here goes!! When I am running the edge on # 3 and getting on it really good it shifts really different. The RPM's will just sit at 3,000, but the trans is not slipping, and then it feels like it is defueling to shift. I have it set to defuel on on locked shifts, so it should not be doing that at all. I have talked to a couple of people with LB7 and they have told me that they had the same problem and it turned out to be the Edge itself. Everything else seems to work just fine. What is going on here? I rode with a guy in an 06 with the LBZ and 6-speed trans, and it shifts totally different. It shifts like I think mine should. Has anyone else ran into this problem? Let me know if you all need some more info, again, it is hard to describe!! Thanks for the help in advance!!

Any ideas, I would like to make sure that I am not hurting anything. I think I might call Eric and Merchant Auto and see what he says!! Please help if you have input!!!!!!

MINE DOES THAT TOO! I don't know what the deal is. When I run it in 2 it shifts fine but #3 it almost sounds like it's slipping but I haven't limped it yet. Let me know what the cure is for yours.

i think mine does as well... 1 it shifts fine, 2 hesitates a bit in between shifts, setting 3 it lags a bunch . i think i'm still having glitching problems with my A2 to though as well... does anyone know if its more of a problem with the Juice modules or the Attitude Monitors that cause the problem????

How many mile do you have on it with the program installed?
Mine took like 300mile before it was perfect.
Also check your fuel filter. It might be plugged and not giving you enough power to shift.
Hope this helps

If it is getting up to 3 grand and sort of hesitating then it sounds a lot like the fuel filter. Also, try the PPE race valve to replace your stock fuel pressure valve. The stock valve has a spring loaded sleeve on it and sometimes it gets stuck which allows fuel to push back into the fuel tank. The truck will go into limp mode when this happens. The PPE race valve is about 40 bucks. I did this and put a new fuel filter on and it was like night and day difference...it runs great now

i just had to update my A2 again, and left the defuel settings to only 4th & 5th gear, and only had the chance to mildly run it do to the weather change up north here, but it seems to have a firmer shift nowin the lower gears


might want to play with the Defuel settings on yours and see if you notice a positive difference.
