Installation was tricky for me but,... simple enough to accomplish. My transmission temps gave been lowered between 60-90° from high to low ambient temperatures. In warmer weather I was getting 191-197° in traffic and now it is running 100-112° in cold weather and 120-136° in warmer weather. It Works. GET IT, INSTALL IT.
