I have a 2003 GMC Envoy Denali that disengaged the transmission over 105mph. "Disengaged" means the transmission literally floated until the vehicle slowed down to 105 before it'd accelerate again.
Hooked up my laptop to the computer, 10 minutes later throttle control and torque management turned off. Problem solved. It'll bury 120 now and has pedal left. Used to be a dog from a dead stop. Punch the gas pedal it literally sat there. Now it at least leaves a little rubber on the pavement. Obviously I don't give a damn about the MPG which weren't all that great to begin with at 15/21.
I like my Ford’s..
Yeah its in the chip, I should have fixed it by now but I got used keeping ‘er down to 90.. unless some dude in a GMC tries to pass..
