42rh transmission

Since the transmission is a RH the original computer told it when to shift to OD and LU based on Speed and thrittle oressure. By using the kit from PATC, it tells the transmission when to shift into OD and LU rather than using a computer. PATC is at transmissioncenter.net I will be using the same kit in my 65 Dart with a 42RH behind a 273/235
