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.

Does exactly as intended. An absolutely amazing product. Simple to install, directions were very easy to follow and if you need visual help there are many how to install videos on youtube. Took transmission temps from over 100C down to 65-70C and actually improved shifting.

Works great on my wives 2015 gmc sierra with a 6l80e transmission. This is a must for your transmission and is worth every penny. The transmission temperature got really high before allowing transmission fluid to flow through. This deletes the trans thermostat. I used this when I rebuilt the transmission. Keep temp about 30 degrees cooler. The warmer o.e.m temp is too hot and burns up the torque converters the you get the transmission stutter. Great product and easy to install.
