How many of you have checked adjusted the movement on the inside of the transmission on the valve body? Mine needed adjustment there also which I did when I had the pan off.

Never understood why anyone would want to change from the stock arrangement. It's worked for me over the past 45 years. You just have to follow the instructions on how to adjust the throttle linkage in the FSM for your car. I guess to each his own.

You would understand if you replaced the stock engine and the linkage would not even connect let alone adjust. Not all of our cars are the same as they came from the factory. Craig

Here's the important part that everyone leaves out. Once you've adjusted/modified the Lokar linkage and lever for the correct arc travel distance as the throttle moves from idle to WOT, it's time to adjust the cable for proper main line pressure rise upon throttle opening. So, you've got the hole drilled in the lever. You've figured out the throttle bracket sweep distance and the correct detent lever sweep distance. Now, attach a pressure gauge to the line pressure port, second one back on the right. http://www.moparts.org/Tech/Archive/auto/19.htmlNow, at hot idle adjust the cable so pressure rises, off base pressure, just as you tip into the throttle, in gear. Don't run yourself over. A cable too tight and it'll have a hard garage shift, late/rough upshifts, and an early passing gear down shift with a delayed upshift. A cable too loose and you'll get early upshifts, no passing gear downshift, and possible slipping that'll destroy the transmission. There is only one correct adjustment position for the cable and only one correct lever to throttle travel ratio. All other adjustments are done elsewhere on the transmission. Shift points are a function of the governor, and line pressure is properly adjusted on the valve body. Good luck

Even using the FACTORY setup , for instance my 1 piece kickdown rod/linkage on my 71 Bee Like the initial poster says , pulled forward all the way on the kickdown lever down on the trans per Chrysler tech using a spring and a tool straight from all the manuals and adjust from there by the carb linkage or how Hotrod and A & A Trans mention this with the kickdown lever down by the trans http://www.hotrod.com/articles/the-lowdown-on-stock-torqueflite-kick-down-linkage/As the kick-down linkage/cable pushes the kick-down lever rearward, it increases line pressure inside the trans and initiates a downshift. “If you adjust the cable so the lever is at the front of its travel range at idle, the line pressure will not increase properly as the throttle increases,” Jason Muckala of Motech Performance explains. “This makes the trans shift too early, and it can cause the clutches to slip and destroy the transmission. I’ve seen people install springs to hold the lever forward, but it’s not supposed to stay in that position at idle.” This photo shows the lever full forward; in this portion of the lever’s arc you can feel no pushback from the lever, an indication that no increase in line pressure is occurring. Somewhere in this range of the lever’s arc, you can feel a slight resistance from the lever’s internal spring. This is where the line pressure begins to rise, ultimately causing a downshift. Properly dialing in the lever’s range of motion is critical to shift performance and transmission longevity. Says Jason: “For the FIRST HALF OF IT'S TRAVEL RANGE, there is very little resistance and the LEVER DOES NOTHING. AT THE HALFWAY POINT, you can feel where it starts to hit the valve inside the trans, AND THATS'S THE POSITION THE LEVER MUST BE IN AT IDLE.” At WOT, the kick-down lever should be positioned at the end of its range of travel. This ensures accurate shift points and a proper increase in line pressure. Factory kick-down linkage setups can create scenarios where the kick-down lever will not move all the way back at WOT, or scenarios where the lever moves all the way back and hits a hard stop before WOT. Now you can begin to understand why it’s important for the bellcrank on the throttle shaft to move in perfect sync with the kickdown lever on the trans in a 1:1 ratio.

Here's my 5.2/5.9 Magnum TV cable that replaced my clunky 3-piece throttle pressure linkage setup. Just had to make a small bracket for the arm of the carb, and weld it to the throttle cable bracket. Also used the Magnum TV lever and mounted the cable to the factory ear on the 727, just as it was on the 46RE it came off of Anyway you could show a picture of the transmission hookup?? Nice setup!! I have a 67 383 727 TF with the stock setup and would like to change it to your setup. Thanks!! Any part number for the TV cable??

Any part number for the TV cable?? that would be the only correct cable type setup to consider using in my opinion. just make sure of the geometry correctness at the carb linkage connection and at the transmission lever.

little hard to see. you have to get the linkage parts off a donor truck or van. there are 2 sets in the pic. Since there appeared to be 2 different kinds, I didn't want to have to go back, so I got both. I used the shorter set. one loads from the top the other loads from the bottom of the linkage.

This is one of several places I disagree with the author. Of course there's dead travel in the lever on the bench with no pressure on the internal valves, but when the engine is running there's pressure pushing on the valves and the lever. The fact that properly adjusted factory linkage places the lever full forward at idle, and the fact that very little throttle input will cause the trans to upshift, proves that lever travel of way less then "half point" initiates a pressure rise. At WOT, the kick-down lever should be positioned at the end of its range of travel. This ensures accurate shift points and a proper increase in line pressure.. Another point of disagreement; in many cases when the linkage/cable is adjusted so that the lever is full back at WOT, the light-throttle upshifts will be late and at WOT the trans might not upshift at all (road speed shift point exceeds engine rpm capability). Bottom line, any anomalies when using the factory linkage are user-induced...plain and simple, the linkage works when not worn out, dicked with or mismatched parts are in place.

I have a few pieces worn out sort of speak
That's why I pulled up another old thread after working on my 71 Bee
The pivot holes are elongated on my 1971 one piece kickdown adjustment

For the THROTTLE PRESSURE LINKAGE (not kickdown linkage) on my 69 440 Charger, I modified a TV cable and lever off of a 5.2/5.9 Magnum. Works flawlessly, cost me $8, and a thousand times better than the stupid 3-piece garbage that came on these cars. Much cleaner too and can be adjusted in 10 seconds if need be i did miss the picture of your setup!
