Turbo-Hydro 350 operation

Hi Bill,

Yes TH-350's have a "kick down cable" for a forced downshift at wide open throttle ONLY. You will have NO automatic 1-2, 2-3, 3-2 or 2-1 shift without a modulator or substitute for the modulator.

You can't drive in a normal maner without a modulator or a modulator replacemrnt such as the kit that B&M used to make. I think it was called a Modulink System and it worked like a TV (throttle valve) cable that senses throttle position and would allow automatic operation.

TH-200, TH-700, TH-355-4L etc use a TV cable rather then a modulator and it works fine.

If this is STREET CAR leave the trans alone and buy a Modulink set-up and let the throttle position working against the modulator and the govenor to control the shifting, because tranmissions are smarter then people.
