I have a 2005 dakota 3.7L 4x4. My check engine light came on today and i scanned it and it popped p0700 "trans control system malfunction" and p0740 torque converter. Have any of you seen this before? I just bought this truck so I have no idea how it's been treated. Any help is appreciated.

I've seen this code on the forums quite a few times. Go with this plan for starters:

  • Change the transmission fluid.
  • Change the two transmission filters, use OEM filters, not any aftermarket brand.
  • Clear the OBDII codes.

Then see if the codes come back, and go from there. Some guys just live with the issue, clearing the codes which come back every so often. That is assuming that there are no other symptoms with the Transmission of course.

FYI, you have a 42RLE transmission.

Welcome aboard.
