Rossler 4l80 with every upgrade possible from them. Built to handle over 1500 hp. Precision industries 3000 stall billet converter and TCI controller. The tranny only has about 100 miles on it and about 8 quarter mile passes with only 800 hp. Tranny works great cost new for all parts was over $8000 selling for $4500 open to offers or trades for viper parts.

 

I'll take $500 off the price if anyone doesn't want the controller.
