i was driving along and the car started to drag,shut off and wouldn't go. i managed to get it to a Auto Zone to check the engine light, and two codes came up. p0700 and U0100, they have to do with the tranny, has anyone had this problem before and what might i need to do to fix it, i would like to know how much money i am looking to need to fix this problem. the first code says, transmision control system malfunction, second code says lost communication with power control module. if anyone has any imput please help... Thank You in advance
