727 TF Linkage

[Woodsman]

ok, 71 Cuda with 727 TF on a SB. Before asked im sure it is a 727 and have a slap stick with Locar linkage. I really have two questions if someone can help, The first one is something i was told and don't know if its right, can you manually shift the trans and not hurt it at all? without a kick down cable hooked up? Its been told to me that when the previous guy who bought this was told by the original owner (not 1st owner) that as long as he shifted it manually nothing would happen to the trans, It does NOT have a manual valve body in it, seems to shift great and fluid always looks and smells good, no slipping, about 100 miles on since i had it so i tend to belive it but do need to ask?

@nd part is the locar cable i need to replace, its really no good, frayed and bad and would like a detailed way to adgust the kick down cable correctly so there is no more manual shifting that has to be done? Any answers i would apprciate, this is all i know about it, and does work well but not sure if its safe to do, hence a new cable set up and hooked up corectly. thanks to any and all for help.

First, the kick down uses a linkage rod not a cable. Second the kickdown rod regulates the fluid pressure in the transmission and is very important to the shifting pressures and the overall life of your clutches if not connected. It WILL cause damage if not hooked up. What type of carb and manifold are you using? How about a couple of pictures?

you need a new cable or if there is room you can shorten the housing & effectively make the cable longer so maybe you can save it .
You want the cable to move the lever fully at wide open throttle , this adjusts the pressure while shifting , shifting manually May save the trans as long as you are off the throttle when you shift
