Ok Dave, I promise if I have to go in and replace the solenoid pack I will get the transgo, if for any reason to avoid the whole lying in a ditch problem.
In other news, I went under the Jeep today and found the harness. It seemed ok but I pulled it off, sprayed it with some electronics cleaner and upon inspection it appeared ok. I sealed it back up and it seems ok. I went ahead and put the 87 octane tune back on, since that didn't seem to make a difference. While I was at it..... wait for it........
I pulled the TCM plug and snipped the torque management wire! :woot:
I love the way it WOT downshifts now when passing, etc.
Overall everything seems fine now, time will tell if the code comes back. If it doesn't I may have to pull the valve body and put in the transgo anyway.
