I've got a 06, 3.7 4wd Dakota that all of the sudden went Into limp mode, I can unhook the battery and reset everything and it will drive fine for a short distance then goes back to limp mode, before it goes to limp mode it'll try to shift to 3rd, the RPM will go up then down then up and back down and that's when it goes to limp mode, I'm getting p0700 and p0733 codes. What could be causing this?
