End of shift tube - 1985 Ford F150

Not hard to replace. But you can't buy them., unless you get the entire steering column. Just did a Ford, same set up. Junk yard part is cheaper.

FIX YA HAS BASIC MICROSOFT ICONS FOR ATTACHING PICTURES TO SOME PROBLEMS ON MY PANEL SHOWS SECOND FROM END FOR TROUBLE SHOOTING VISUAL PROBLEMS. COOL TWENTY BUCKS AT AUTOZONE CAN GET SERVIVE MANUALS AND THE PUBLIC LIBRARIES. SHIFT TUBE DOESN'T COMPUTE CORRECTLY DO YOU MEAN TAIL SHAFT FOR AUTOMATIC?

Most likely, either the shift tube is damaged/broken or the screws have backed out of the lever at the end of the shift tube that the shift cable connects to. If the shift lever feels really "floppy", then you probably have a broken shift tube. You will probably have to pull the steering column down to get a good look at the shift tube to see if it is broken and to see how much play is in the shift tube bushings. Also look to see if the lever at the end of the shift tube is loose (shift cable lever).

A little word of caution: If you take the steering column down, be sure to disconnect the shift indicator cable first so it does not get broken. There is a tiny screw in the plastic braket that must be removed then the cable loop will simply slip off of the nipple on the shift tube arm.

Anyway, you will need a T-30 torx bit to work on the shift tube, the shift tube bushings and the lever at the end of the shift tube.

I made you a graphic below to help you understand what I am saying. Please note that it is NOT necessary to remove the steering wheel to do this, but you will need to remove the upper steering column shrouds if the shift tube bushings are loose.

At the end of the steering column, under the dash is a steel bracket that the inner portion of the shift cable is attached to. There are two t30 torx bolts affixing this bracket to the shift tube in the steering column. These bolts commonly come loose. You will have to stand on your head under the dash, but tightening these two bolts will solve your problem.

Inside the engine compartment is your throttle cable.
On that cam looking thing on the throttle body where the throttle cable is attached,just behind that is another cable with a little round ball of lead on the end.
That has become detached from the throttle linkage housing.
IT' S HAED TO FIND SOMETIMES,BUT LOOK DIRECTLY BEHIND THE THROTTLE CAM HOUSING FOR A LITTLE TUBE THAT PROBABLY NOW LOOKS LIKE A TUBE WITH A LEAD BALL CABLE COMING OUT OF IT.

The shifter linkage has a two piece plastic / nylon bushing at either end of the gear shift tube that goes from the gear shift lever to the transmission. As the bushes wear through normal usage the gear shift becomes sloppy. The bushes at the gear shift lever end usually wear out first.
You may have to drop the exhaust pipe to access the underside of the gear lever as there is not a lot of space to work in above the exhaust.
To replace, remove the securing nut and through bolt where the underside of the gear lever U section attaches to the tube. Pull down the tube and the worn bits of the bush will come out. Place the new bushes in either side of the tube and put tube end back between the U section. Replace the through bolt and nut. If still a little sloppy, you may have to do the transmission end bushes as well.

There is a small string-like cable incased in a plastic tubing that runs from the instrument cluster housing that the indicator sits in, the opposite end is looped onto a hook on the shifter on the steering column. Follow the plastic tubing till you get to the end. There should be a tiny adjusting gear with threads. Turn the gear until your indicator aligns with the correct gear. (Note: you must disassemble the column trim to see the tube)

Standing in front of the car walk around to the passenger side and look in to where the gear shift arm comes through the fire wall you will see a gear shift tube bellows with a clamp and bolt coming through and at the end you will see the "gear shift guide control"(7) there is a "gear shift control mode" (6) that clips over a round ball at each end one clip faces front and one back ,one towards the middle of the car and one closer to the passenger side of the car , this had come undone at both ends and dropped off, by replacing this the problem was solved.
The part numbers ( 7 ) and ( 6 ) are from a shift linkage diagram pages 21 and 22 found on the internet through http://www.daewooclub.cook/forums/showthread.php?tid=1002
I hope this is of help to someone else out there
