    Did Ford have different valve bodies for column shift vs floor shift on C6 trans? Someone halfway put a car together and I am finishing it. The trans which was rebuilt and appears new, inside and out did not have the floor shifter attached. Guy I bought it from said he had a piece of linkage missing. I scoured the car and came up with a piece of linkage that looks right. But instead of pushing the linkage and therefore shifting the gears, it just binds up. Upon inspection I have determined that the shift detent out of the trans is upside down? Possibly?? I have always messed with 4 gears and dont really have any autotrans experience. Anybody have any tips for me? Or should I just give up and start drinkin????

    If I read you right the manual shift lever on the outside of the trans is upside down. The valve bodies are basically the same, some trans had the detent spring bolted to the case and some were bolted to the valve body. That would not affect the direction of travel on the shift lever unless they have mixed up some parts from one style to the other? There is a nut on the inside of the case that holds the shift lever linkage on to the shaft, you can use a 7/8 wrench and remove it. The shift lever should have a flat on each side to go into the linkage, pull the shaft out an rotate 180 deg then reinstall with the lever on the outside either up or down depending on what type shifter you are using( push or pull). Tighten the nut and reinstall the valve body. Make sure the end of the manual lever is inserted into the corrett slot in the manual valve in the body itself along with the kickdown lever in its proper position. Is kind of hard to diagnose without visual inspection on my part but this might help you see it for yourself.

    Thanks Old Guy!!! I did drop the pan and discovered just what you said. I didnt have the car high enough in the air initially, so was not able to get enough working room to actually remove the shift lever. I did go out and get some 6 ton jack stands and now the car has the altitude to work under. There is a flat piece of metal that is bolted in that has a roller on one end of it and a small opening to allow to catch the end of the inside shift mechanism. While trying to remove the 7/8 nut it popped out of its place and is being a pain going back together. Any words of wisdom on that one??
    Thanks for your help!!!

    What you will probably discover (same way I did) is that the transmission you have came out of a colum shift application. And that depending on the vehicle it was originally installed in, it could have any of several dozen different shift linkages installed in it. The linkage is particular to year, and model of vehicle with different lengths, angles and bends in it. When you finally get one that moves in the correct direction, you then have to lengthen or shorten the trans linkage to get the correct ratio in relation to the length of the shifter arm for the shifter you are using.

    i.e. if the bottom of the shifter handle moves 3/16ths of an inch between each gear, and the trans linkage moves 1/4 inch between each gear, your shifter will not indicate correctly and the detents will not relate to what gear you are really in. Often, it is easier to use an aftermarket cable operated shifter than it is to try and get the ratios correct.

    Good luck!

    Linkage Problem

    With the trans in the car it is a real PTA, patients and perserverance is the only advise I can give. A little constructive cursing might help too. Xtra set of hands from a buddy may work too.

    You need to install the shift lever for a floor shifter - it will point about 160 degrees up from where the one you have does.
