I finally finished most of the mods to my 2013 JKU yesterday, which included 4.56s and 35s. After setting ratio and tire size with my procal the trans still goes into limp mode, stays in 2nd gear, and gives me incorrect gear ratio codes. I redid the programming several times, unhooked the battery for 20 minutes, cleared everything with a scantool, and messed with it for 2 hours with no luck. It honks the horn and everything like it's working, but it isn't. Tomorrow when I've got some time AEV tech support is gonna help me troubleshoot it, but I was just wondering if anyone has had such an issue? I'm a bit worried about what I'll do if AEV can't get it to work, seeing as my JK is un-drivable now...

 

Looks like a simple fix. Apparently I've got the wrong procal and it was boxed wrong so they are sending me a new one. Problem should be solved tomorrow. Great support from AEV in my opinion.

 

Glad you got it worked out... AEV is always good to deal with!

 

Another good service by AEV guys, couple of buddies here are impressed with their service either.
