Yes exactly the same for 2004r and 7004r. you will need to use a 4th gear pressure switch normally open. When you enter 4th then it will close grounding the solenoid. the most simple setup is to run a wire from the + side of the TCC solenoid to power thru a switch. Once your in 4th, flip the switch feeding +12v to the TCC solenoid and it will lock, when the trans downshifts to 3rd or lower, the pressure switch opens and you no longer have ground to the solenoid thereby unlocking the converter.
