A friend just bought a 68 charger 383/727 combo. The car runs & drives real good. He drove the car home from the seller's house which was 450 miles away without any problems at all. When we started checking the car over, we discovered there is no kickdown linkage for the tranny. Someone pulled the kickdown lever on the tranny all the way forward & put a spring on it to keep it there. My friend said he did not get on it at all on the way home & babied it. Is this tranny toast, or if he puts a kickdown set-up on it (Bouchillon kit)& sets it properly will it be OK? He said when he was checking out the car, he was so excited, he just didn't notice that the linkage was not there.

The "kickdown linkage" really only increases line pressure.
If it was babied then there is a good chance it's OK.
Really, though, if you don't know it's history the seals and clutch material is going to be pretty well shot unless it was rebuilt at some point.
I just did a '73 727 with 60k orignal miles. While it looked VERY nice inside there was evidence that the bands and the clutches were starting to flake after 35 + years of use and the seals were hard and brittle as well.

Max pressure is all the way back.
Then why would you put a spring to keep it there? Some of the stuff you find on these cars will make you go nuts

As you know, it just "kicks down" the gears when you boot it (old term!)...let us know what happens!!!

WRONG The kick down linkage is a misname for the throttle pressure control linkage which more than anything else controls pressures in the transmission throughout the travel of the throttle and controls shift points with out clutch slippage.

SORRY GUYS!!! That's what I was always taught - my apolgies for bringing BAD info to the game!!!
But my appreciation for the better info. Funny, becuause I knew it increased line pressure, but thought that's what held it in gear longer...isn't that what it would do in the end??

If you drain the fluid... adjust the bands!
Just did the regular maintenance on my original 67 727, which started screwing up the 1-2 shifts. When I got the car someone had disengaged the linkage too, no idea how long it was run like that.
Adjusted the bands and the linkage, changed fluid and filter. Installed the smallest Transgo towing shift improver kit with conservative setting (drilled the holes to the medium size they suggested). Have a perfectly shifting transmission.

...my tranny isn't toast!!! I put the Bouchillon trans cable on my tranny, adjusted it properly, changed the fluid & filter (even though it was red) & adjusted the bands. I test drove it for over 100 miles the past weekend & it shifts perfectly now without any problems! I also got my emerg. brake cables set up on & working good(another post). 
It's nice when things go good 
Thanks for the input everyone!
