Hi Doc
I have mine all sorted now it runs like a new car. The TCM I got from
bobby@rtpartsco.com
$500.00 inc freight plus it needed reprograming at Jeep....Sunco due to error code in the new TCM P1644 incorrect config.
Error codes that instigated the change of TCM P0605 TCM Rom failure. plus the TCM would not communicate with any of the other modules.
I also tested the BUS Voltage on the DLC pins 6 and 14 @ 2.5 volts which confirms thats working.
My Jeep was stuck in Limb mode.
My local mechanic got a code pointing to internal TCM failure and suggested a new gearbox....5 grand plus ouch ....
I brought the Autoenginuity scan tool with the chrysler enhancment $500.00, can be sourced from Sydney....worked good pulled the jeep codes out and cleared them.
By the way the TCM is not where the USA says it is, its behind the radio right against the inside firewall.
Also Bursons Autoparts told me they could repair and test the TCM, after four days they told me they cant test it and I had to pay the $67.00 and they would not give me my TCM back unless I did.
So if anyone wants a broken TCM for a 2006 jeep....Bursons have one!
