slow speed.also when in a turn? Not all the time. But enough to be scared to drive my kids to school. Check engine came on when it jumped into drive. Did key trick and got 0700 tcm. Could it be anything else? Fluid/filter, a sensor? Just replace it? I have 96 caravan as well. Are the tcm' s the same model? Swap? Thank you in advance. Any direction would be helpful.
