is it possible to install a overdrive shutoff in the transmission. it seems to me that if we could find the right servo we could wire in a power switch. does any one have any thought or experiance with this?

Correct me if I am wrong, but selecting the "3" on the gear shifter in essence turns off the 4th gear (overdrive), does it not?

With a wiring diagram you could cut the proper wire to the trans and install a switch to do this, or 3rd as stated, but why? Or do you mean the lock up convertor?

i do alot of towing with my suburban and in hilly area's the trans shifts in a out of gears. if i put in 3 will it still go through 1 2 then 3? or will it just be in 3 the whole time?

It should start in first gear when the selector is in 3 and then shift into second and then third

Why not just use 3 gear position on gear shift?

i guess i never thought of doing it that way but i will give it a shot and see how it does. thanks for the help

You are welcome.
Let us know how it goes.

well i took the trailer out today and i guess the simple solutions are the best. i was just trying to complicate things.
