So when I got my '24 the catch was that is was stuck in 1st gear. The PO thought that the clutch was broken but he was wrong. The car rolls when the clutch is down and drives in first gear. That's the only good news. The shift lever moves around in it's boot very easily, the clutch has no effect on it, and there are no definate spots where it goes it just goes all over the place.

So pretty much you can reach in through the window and move the shifter around in any direction.

I took off the boot and it all looked fine.
The problem is not the clutch.

I had assumed that the problem was the shift rod either being broken, bent or having a faulty connection at either end.

Here's a picture: when I move the shifter around the GREEN rod moves and it moves the RED lever. That's all that I can see moving.

If anyone has experienced this problem or has any ideas of what to try next to dropping the tranny I'm all ears

thanks guys

Im having a similar problem right now, and I think that my shift rod is bent as well, the one you highlighted in green.

Are you able to change gears by manually manipulating the intermediate shift lever? (The red thing on the transmission), and is it properly connected to the shift rod (green). It should be secured with a screw that has a hole though the head in which there is supposed to be a wire to secure it.

Also, look at the diagrams of the intermediate shift lever and its connecting parts on the transmission (you can download the PET which shows all the parts for the car) and make sure that everything is connected and nothing like a screw is missing somewhere.

Also, there is a cover on the right side of the audi transmissions held on by three screws, if you remove that panel you can in the lower part access the shift selector rods, and force it into neutral by the help of a screwdriver that you use to move them. I don't think that's your problem, since if it was, you shouldn't be able to move the shifter to the left and right. If you open that panel, be careful, and don't move the shifter sidewise, or you will end up having to drop the transmission to fix the new problem you use made.

there is a bolt which is in the tranny end of the shift bar (green part) make sure this is tight or it wont be able to change gears either.

you should also be able to change the gears with the engine off, can you?

Is the bottom of the shift lever secure in it's mount?

if it just flops around and is hard to find gears, check my first post!

The bolt was tight, when the shifter is flopped around, the shift rod moves fowards and backwars all of the length of the rod and it moves the shift lever. The lever is the last part of the system which I can see moving.

The easiest ways to see if it can change gear is to see if you can get it into neutral, or if you can get the transmission totally stuck by putting it into two gears. Try to push on the car to feel if you get any difference on whether the stick is at the front or the back.

There is a bolt on the intermedite shift lever on the transmission which is used for regulating where you will find the different gears sidewise that can come loose or fall off. That might give you trouble changing gears, however, I think if that happens, you should have at least two gears to choose from in addition to neutral, as you lose the possibility of actually moving the shifting mechanism to the sides.

Also, you might be able to hear or feel if anything is happening when you try to change gears.

If all fails, and you are very, very, very sure that everything is connected properly, then it's a relatively small job to drop the transmission (1-2 hours for removing, the same for fitting it depending on how easy you can figure it out), a search of the forums ought to give you lots of results on how to do it.

OK, this is the SECOND time this beast has gotten stuck in second!!!

I don't get it. Last time I had to drop it to reset teh stinking forks and there didn't seem to be anything wrong with them. Now only 200 miles later it has happened again!! (lucky, it happened at home this time) It always happend when I am using reverse. The 1-2 fork ends up in second the the main lever not in the forks slot anymore. This mandates dropping the trans, pulling the gearbox and resetting everything then re-assembling. What I can't figure out is how this happends. everything seems to be tight with no slop in any sliding mechanisms.

Any ideas/help?

Aren't the shift forks supposed to be pinned onto the selector shafts?? Sound like you don't have pins, or they're breaking?

If you switched trannies you should have changed the shifter rod also. 4 speed to 5 speed then you will need the 5 speed shifter bar. Worn bushings will cause you not to ship properly.

It is the original (Sep '76) 4 speed transmission.

Terminology that I am using that may not be right SHIFT SELECTOR: the part that moved sidways to engage the 3 SHIFT FORKS: the R.. 1/2 & 3/4 and upll one of them into the deired gear.

What is what has me scratching my head. I have had this thing out twice now.

The first time we lost the 3/4 fork. It had no pin and it rotated and opened a gap so the selector couldn't engage it.

Pulled it out tore it down and installed the missing pin.

Next, I was parking at work, first it seemed to stick in reverse and the lever lost the correct feel. after some "stirring" it ended up in second without the selector in the 1/2 fork.

pulled it out, inspected it re-aligned everything put it together and back in.

This time is the same, backing up, shifter feels odd, pull forward now shifter is limp but NOT disconnected. Car is again stuck in 2nd.

The ONLY explanation I can figure is the thing is partly in 2nd when I go to push it into reverse, then, when the selector leaves the 1/2 fork it pops into second. Of coarse, with the selector out you can't grab it to get back to neutral.

Is there some device that is meant to only allow the trans to move one fork at a time? (the ball detents?)

At this point, I am seriously thinking about cutting enough out of the spare tire well to allow me to pull JUST THE GEARBOX. This would make repairs much easier and faster.

I sort of hijacked this topic in the last few posts from Tom-15 but I suspect that his has the same issue and it is not the external linkage.

Ya, it wasn't the external linkage,

After dropping the tranny, I opened it up and the problem was that the small tab on the shift bar was broken. I had to order one from Germany (pita). After waiting for over a month, it finally came in last week, I installed it and I am putting the tranny back in.

problem solved.

[geddes66]

That's good news. How much did it cost? Exactly what part was broken? I wish I could have found a fault that obvious. Maybe this time I will.
