Hi everyone, thanks in advance for your help. I have a 2006 TJ diagnosed with a bad PCM. Dealer ran the part number and it shows it is for a 2005 automatic. My vehicle is a 2006 six speed are the PCM interchangeable I know there is a big price and availability difference between the two dealer technician says they are programmer does not give details as to the transmission of the computer. I am assuming they are interchangeable since I purchased the vehicle with this PCM and apparently not the original. Thanks again for your help.
