I have a 2009 jeep sahara rebuild i had got a deal on a 2010 rubicon drive train after install trans is in limp mode to to shifting code. My question is what program is best for this budget build or even if i have any other options if any.
 
Transmission limp mode could be the tire size doesn't match the info in the ECM or the gears are different then what's programed in the ECM.
