Hi Chris,
can I ask you how did you solve the problem? I have the same error P0730 on wrangler jk 3.6 year 2012 with 35 tires, the third gear does not enter and the car goes as if it were in neutral. thank you very much
Hi, welcome to JKO. You are replying to thread that has not seen any action in over 3 years.
Have you used a programmer to set your JK's tire and gear ratio? The easiest way to do this is get your hands on a Bluetooth OBD-II module off Amazon. I use an OBDLink MX+ however, I would not pay what they are charging for them these days. You will also need the OBD JScan app for your phone.
