You're not hijacking, it's ok. On top of the shifter linkage where it rotates on the trans to select the gears there is another lever . I assume kick down ? The cable was off of it just hanging there . I wiggled everything loose, lube up a bit and re attached . Should the kick down lever rebound on its own ? It try's. But not to much. Also,the thing under the exh manifold is a trans fluid warmer ? Piped into a/f it looks like .? Do I really need this ? It also has a cooler up,front . Trans lines are rotted is why I ask . Would like to just run to cooler up front .

Sorry to hijack I will get a thread for this truck soon so I don't have to litter all,over . Lol.

That is the throttle valve for the valve body. It is extremely important to have it hooked up and adjusted correctly. Yes, it springs back sort of on its own. They usually have a spring coming from a bracket on a bell housing bolt to return it. Without this cable hooked up, you can burn your trans up. As throttle increases, the tv valve increases trans pressure.

That big cooler is a torque converter heat exchanger. It's purpose is to help warm the trans to operating temp in the colder temps, and help cool the torque converter in warmer seasons. I've ditched many and added a large external cooler in front of the radiator and been just fine.
