    I am posting this here for Bill who asked this through the comment form.

    I have a 2005 chrysler town and country van. At 104,000 miles the check engine light came on, code p0700, transmission problem. Took it to the mechanic who said it needed a new solenoid pack. He replaced it, then 4 days later check engine light again, and same code again. Any suggestions on what to try now???

    Thanks!!!

    Your technician did a great job isolating the solenoid and solenoid servo pack on the first pass at this. The problem with this, though, keeps on being the check engine light and the P0700 fault code. The issue is that this is a general transmission fault category that tells the technician there is a transmission fault somewhere and that he should be looking for it. The code is generated and stored by the Transaxle Control Module that watches the sensors and actuators in the transaxles. If it finds a fault or a fault is indicated anywhere within the transaxle the P0700 fault code is logged. Your technician’s next step here is to plug in a diagnostic scanner to find the specific fault. Those faults are not stored in the TCM but in the PCM (Primary Control Module or engine computer) and the scanner is the only way to access them. Until the technician does this, there is no way to know why your Town & Country’s fault indicator keeps sending the P0700 code.

    The troubling part, though, is the check engine light. The TCM is not supposed to be able to activate the check engine light. It is only activated by the PCM. This indicates that there may be a problem that is over and above a transmission fault. Again, the only way to find any specific problems — engine or transmission — is with the diagnostic scanner. It will likely cost you about $100 or so for the engine check, but you will have to invest in the diagnostic scan to find the answer.
