However, the "kickdown rod" controls not only the kickdown but the line pressure in the transmission. it absolutely MUST be hooked up and adjusted properly on a 904 or 727 or the transmission will shift totally wrong and/or burn up quickly. Don't listen to anyone who tells you to leave it disconnected or to wire the arm all the way back or any other shadetree BS. Follow the FSM procedure and adjust it right.

yea he said it controls line pressure to trans also

The guy doing trans tells me to have someone push gas pedal to floor,and some one else under neath pullin leaver fully towards rear,and rod should just drop in hole,do not force it either way,It should just drop in hole,if it needs moving adjust the end of rod till rod drops in.....
He builds them so I guess he knows what hes talkin about...

No, that is wrong. When I get back home I will scan you the right way to do it out of a FSM.

The kick down lever needs to be at full when the gas pedal is at full throttle. Basically the same stroke as the gas pedal. gas pedal up, lever is forward and relaxed,,,,, gas pedal down at full throttle, lever is all the way back. Basically simple if you have all the stock linkage. Mine is all Lokar cables but works the same. Any yes you can tear up a good tranny if that kickdown is not adjusted right. 727's are a little tougher than most but it can't be adjusted wrong forever.


Cheers!

I'm too lazy to scan the FSM right now, but here is the procedure from an old Chilton's I already have scanned:

What a coincidence, I was just asking about this kick down stuff in a new thread I just made. Any way I'm only interested in theory rather than actual adjustment since I will be altering (if needs be) my present linkage to suit my Edelbrock setup. By the way Heavy the adjustment procedure (for stock) is covered in that ATSG Manual I linked earlier, but not where the lever is at different throttle positions which is what I'm looking for. What Phoenix said basically agrees with my interpretation at this point though.

I do have a copy of the 1979 FSM and to be honest it doesn't say anything about adjusting the linkage at wide open throttle.

Basically it says to make sure the engine is at temperature, open the throttle just to the curb idle notch on carb lever (make sure choke is open). Then from underneath the van loosen the adjusting screw and let the spring make the actual adjustment (the spring yours is missing at the moment Heavy). Note: Manual says to make sure the throttle valve lever stays all the way forward during the adjustment.
