hi
well i will have to retry it agin ,but as i recall if i have my trany in 4 od with switch locked position and just hit the od button it will stay in 4 od unless i turn off lock up switch, or drop my mph below 28 mph where my psi switch automaticaly turns of the lock up !

 

RUSS ROTH, Yea thats what Terry did for me too. Asked what I used it for, What mods I have and what mods I plan to add in its life. All the way down to if I pull live stock or other (shift firmness control haha.) If I remember right, I told him I want to be able to handle 700hp. Dont know if i'll ever get there but its nice to have the trans that will take me if I want!
