You should align the TCM with the locating pins on the module mounting bracket, install the TCM by seating it fully into the bracket until all of the retaining tabs have engaged the edge of the module edge, connect the TCM electrical connector to the TCM, lock the TCM electrical connector securely to the TCM by pushing the retainer toward the electrical connector until fully seated, programmed a replacement TCM with the proper software/calibrations and reset the transmission adaptive pressure values.
