Depending on the unit, you can connect directly via OBD to the ACDelco T87A, or operate in BENCH mode (on the bench without opening the control unit) on ACDelco T87 and Bosch T93.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Quickly and safely access a wide range of GM vehicles from 2015 onward: pickups, SUVs, and muscle cars with 3.6L, 5.3L, 6.2L, and 6.6L petrol and diesel engines.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">With these new protocols, you can:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Read and write TCUs safely.<\/li>\n\n\n\n<li>Customize shift timing, pressures, and torque management.<\/li>\n\n\n\n<li>Improve ECU-TCU interaction for smoother and more efficient driving.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><br>Brands included
