No cable but now that you mention it there is two nipples on the throttle arm as though a cable should be there, did the cable supercede a rod arrangement? my 280 coupe has a rod that goes to the transmission tightened by the throttle action, incidentally, the transmission on the coupe and the one on the TD are identical looking apart from the arm and rod arrangement, what is the purpose of the cable/rod, is it to do with shift timing? I assumed it was to do with the kickdown, could I retro fit a rod or cable to my TD transmission? I have a spare rod and arm that came with a transmission I took from another 280 Coupe as a spare for mine, I ought to be able to fabricate a linkage from my throttle arm to the rod fairly easily if this is the answer, it could be that the original rod has been removed previously for some reason I will have to make a closer inspection. perhaps this is where I have been going wrong all along ie a vital part of the setup not present ?
