I am going to drain and refill the Fordo on my 56.There is an adjustment to the band which has to be done with the pan removed.According to the transmission manual you need a special tool to correctly do the adjustment.Can anyone give me an easier way to do the correct adjustment without the special tool? I believe it simply needs to be set with correct amount of clearance to the adjustment screw.Thanks

Mark: Adjust the intermediate band to 1/4" clearance between the tip of the adjuster screw and the servo piston pin. There is also a 1st/rev band adjustment on the outside of the trans on the passenger side. Loosen the lock nut, turn the square headed screw in until it's "snug", and back it out 1 1/4 turns and tighten the locknut.

Thanks John.I thought there must be a more straight forward way to to the adjustment than the "song and dance" method suggested by the Fordomatic manual.

John: On this topic but slightly to one side, on a 57, can the 2nd gear shift to drive be adjusted to occur later? Mine at light throttle shifts very early.. Thanks

Any chance of a pic John or a bit more of a hint with the internal adjustment measurement???

Paul: Adjust the kickdown rod that goes from the bellcrank on the manifold to the transmission. Lengthen it a turn or two at a time and try it until you get it like you want. Dutchy, sorry I can't do a picture. With the pan off, you'll see a round aluminum servo near the front of the trans. Attached to it is a lever that will remind you of a rocker arm. The adjusting screw contacts the stem of the piston inside that servo, that's where you want the 1/4 inch clearance. Pry the adjusting screw end of the lever away from the servo to measure the clearance.

Hello John,I took the pan off today and pulled one of the drain plugs out of the convertor.Do I need to pull both plugs out or will it drain OK from the one?I see the adjustmen to be done.Won't be hard to do once all the fluid stops dripping.Is there anything else I should check while I have the pan off?When replacing the pan gasket do you put sealant on both sides of the gasket or what is your way of doing this so there are no leaks after?What is your suggestion for fluid type to put back in?I was just reading PF Arcands question.Does that rod not just control the kickdown for when you want to kick it back up one gear?I thought the modulator valve controlled shift points?What year did Ford start with the mod valves? Thanks Mark

Mark: On the models without the vacuum modulator, that rod is referred in manuals as the "throttle pressure rod", and that's what it does, along with the kickdown. On the modulator equipped trans (came along in the '60s Cruisomatics) the rod is the kickdown rod, as you say. On those, there is usually an adjustment screw, accessible through the vacuum hose fitting, that can adjust the shifts. I still use type F or FA fluid, you will get varying opinions on this issue. Your converter will drain with only one plug out, but it takes longer since the air has to get into the converter through the front pump.

Thanks John!Any tips on reinstalling the pan so it doesn't leak?

Mark: I just take a hammer and tap the area around the bolt holes back flat, chances are someone sometime has overtightened the bolts and distorted them. Forgot to answer your other post, I install the gaskets dry. If you prefer sealer, use it sparingly.

Hello John,I have finished the trans service and I have NO leaks.I have been adjusting the linkage as per the Fordo manual.I have the rod 3 turns longer than where it just fits and I have the gas pedal as high as I can adjust it.I still can't get it to kickdown when floored if I try to get into passing gear.The manual warns against adjusting the rod too long or it may cause trans damage.How much longer can I go?2-3 turns more?It does make a big difference in the way it shifts now as opposed to before I adjusted the length.What is being changed as the rod length is adjusted?

Mark: Comtrol pressure is being changed by changing the rod length, the longer the rod, the more pressure. Have you checked to see that you get full throttle when you depress the accelerator to the floor? If anything stops the travel before you get full throttle, you won't have kickdown. If you get full travel, adjust the rod some more until you get kickdown. I assume your are looking for kickdown from 3rd to 2nd below 50mph.

Also make sure that you are putting a 1/4" steel rod through the holes on the bellcrank to align the linkage before you start adjusting the kickdown rod (very first picture in the manual posted herein). That is crucial to making sure the geometry overall is correct. If you dont start there, it may never move enough to kickdown.
