So after spending $2k to get the Kj's trans solonoid block replaced two weeks ago the issue is back again.... Same symptoms as last time. I don't know what code it threw this time as we were outside of Lithgow with a 4hr drive home so I just pulled the battery +ve lead to reset the computer.
Luckily the issue didn't come up the rest of the way home but I'm in a bad place with the KJ at the moment. Evil thoughts of trading it for a Prado or Pajero are circulating around my head....
