Just wondering at what speed should the Ford-o shifts at under normal exceleration and faster exceleration, also what is the normal or top speed cruising that it would normally kick down?

I seem to remember the factory shop manual talks about up shift and down shift points along with the kick down adjustment.

Are your shift points really early or late? Mine tends to shift up very early under light excelleration. Haven't tried to adjust it yet. Due to a lot of slack somewhere in my 57s driveline, I avoid using the throttle kickdown, so can't comment on it..

If you pm me an email addy i can scan and send the specs out of the service manual. Mit lists wot upshift points, downshift, etc.

Rob - Did you ever check to be sure your 4160 carb can get to WOT? We recently had a thread on here with Moz about getting his Holley throttle lever to work with the Fordo linkage.

PF , ..Guess its why Im askin' I dont really know if its early or late shifting?

Ron , I'll email you , thanks

Steve, Yes I am getting WOT ,you helped me out with that one. I do find it hard to understand the geometry of the bell crank and how it works on the kick down, I have been turning a blind eye in the hope that it "just works"   Ive had enough problems working it out on the Cuda !

Had a bit of a play with it yesterday arvo and made sure things line up with the 1/4" rod thru the hole. I extended the kick down [ok its not just a kick down!] 3 turns. On a moderate exceleration changes gear around 30 mph. at this point I can "feel" the change its not a harsh clunk but I feel going much more the shift will become hard. The other thing is that it wont "kick down" above 30 mph.

I wondered at what should the maximum speed be before its capable of shifting down?

I have a copy of the Fordo Manual I can give you.

Do Y Blocks Downunder run upside down? Gravity Sucks!!

Rob - Got home and into my "blue book" on the Fordo - borrow one or buy one for a reference book when you get a chance. Can't scan it here - but you need page 24.

'56 car 272/292:

3.22 axle 

upshift 2-3 at min throttle = 12-20 / at max throttle 60-67

downshift 3-2 at min throttle = 14-7 / at max throttle 67

3.55 axle  

upshaft 2-3 at min throttle = 11-18 / at max throttle 54-61

downshift 3-2 at min throttle = 12-7 / at max throttle 61

Here is the chart out of the manual for shift points.

I went through and set everything again and moved the pedal about 4" away from the floor its a a maximium, lined up the bell crank hole etc I set the "kick down rod"  [sorry for not using correct term] so it slides back in its pin then 4 turns out making it longer and so far getting close to those shift points. At WOT doesn't seem to hold and changes [up] probably more around 40-45 mph. Its not kicking down either . I found the kickdown mechanism very stiff, can someone easily explain how the kick down mechanism works at the bell crank, Got me stumped?
