hey guys. i have a 96 k2500 with the 5.7 4L80E tranny. its stuck in 2nd no matter what i do. even if i drop it in 1st on the column. i have read that 2nd is the default if the tranny losses power to the solenoids. i just replaced the input speed sensor and that dint do anything. im going to replace the ignition switch next. i want to take the connector apart and clean it up but i don't know where it is under the truck. i poked around under there when i changed the sensor but i couldn't seem to find it. any help or opinions would be greatly appreciated. thanks.
