Default Input - help on 3.21 gears on JKU

Guys can i please get your opinion or suggestions here...I purchased my 2012 Jeep Wrangler Unlimited Arctic Edition - 4 door new...
As you might know the Arctic package has the 32" Rubicon tires - Auto with 3.21 gears...When new it did not seem to
always want to search or change gears alot ( even on flat ground )...
This past summer i purchased 17" rims - 35" tires - Smitty XRC front & rear bumpers...I know more weight gonna make
transmission want to change alot...Even with AEV same thing...I accepted that no problem...
Real question here i put on my 32" tires & rims for the winter...It's been 2 weeks now i'm going frigging nuts...On a flat
surface transmission ALWAYS seems to want to chane...Looking for a gear...I have to always ride the pedal...
Is this really normal with the Auto - 3.21 gear set up...or just something needs to be reset from dealer...
Really would like input here guys...Thanks...

Did you do something to change you shift points like a Procal? I have 37's and 3.21's and mine doesn't hunt at all.

Yes did the AEV...I thought it did not do anything with shift points...I recalibrated for 32 tires ok...Is there a complete reset on AEV...

use the procal to set it back to factory settings. or measure you tires and reset it that way
