This is the best tool to understand my new compushift setup

Ordered the compushift controller for a 4R70W after looking at everything else on the market. I ended up going with HGM simply because of the blue tooth for phone access and the fact that they use a CAN adapter to read data from my EFI system. After the simple installation everything worked flawlessly the first shot. Not to mention the billet controller case is super nice. I mounted it in a place I could see it. Why hide it if it adds style to your ride. Im a for sure customer for life. Customer service is above and beyond.

This place does it right, not just with quality products, but unmatched customer service to go along with a quality product...in my eyes, if you need a stand alone trans controller, there is no other choice, do yourself a favor and start here, this is the only company that offers Wi-Fi tuning help while you're on the phone with them. Truly a top notch operation
