1. If you did not clean the ATF cooler after removing the transmission, and you are installing an overhauled or remanufactured transmission, clean the ATF cooler (see ATF COOLER CLEANING  ), failure to do this can cause a repeat transmission failure.
2. Install a new O-ring (A) on the torque converter (B), then install the torque converter on the mainshaft (C).
   NOTE: Make sure the torque converter is fully engaged on the mainshaft, the stator shaft, and the ATF pump drive gear. Failure to do so will result in severe transmission or engine damage.
