The 350 used a cable for downshift only. They would have been installed on all T350's no matter what the engine. I have a few brackets off 250 engines for the kick down cables. Mostly later model stuff. I will send you a picture of one so you know what they look like. I have been running a 250 with t350 for a few years with the cable hooked up. They work just fine with out them, you can manual down shift. The internal pressures are not effected by the cable unlike a T400 which must have a down shift switch. Joe
