I used to use the gov pressure is about the same as road speed to test gov press but I found these tranny's to be off just a little but they actually use the trans output shaft sensor to determine gov press. The factory will have lock-up even in 2cd gear on the newer ones but you could just do it in 3rd or od and use a certain speed to be above for lock-up. Same with od as it will have to be in 3rd and above so much speed for od to engage. Good luck with it , Ron
