74 2.0 side shift

Daily driver. One day on my way home I could not get the shifter over to the 4th & 5th gear plane. Worked fine that morning. When I went to leave I started the car in neutral and when I pushed in the clutch I heard a significant pop. I thought the clutch cable tube may have popped and be blocking the shifter in the tunnel. Took all that apart and it appears to be fine both in the tunnel and at the firewall.

Engine and transmissions mounts appear to be correct and tight

Bushings and conical screws at both the firewall and transmission appear to be fine and tight. I had gone through all of them about 5 years ago.

Had the wife wiggle the shifter towards the 4/5 plane and can see the shift rod is hitting the top of the hole in the engine mount bar.

I don't see how the pop I heard when pushing in the clutch would correlate to the shift rod now hitting the engine bar.

I did drive it to work one more time since it happened. I stuck to the back roads where I did not need to go over 50 mph and everything else is working as normal as it always has.

Thoughts? (IMG:style_emoticons/default/beerchug.gif)

Okay, shot in the dark...How are the splines on the shifter rod? could it have skipped a spline? Also at the trans shifter console. the rod coming from the interior of the trans itself is two pieces. did that shift out of place? It would only need to drop on that shaft a bit to mess the travel up. Hope it's a cheap fix

If the linkage did not move then you should check your shift bushings and rubber motor mounts.

And the firewall bearing. Get Tangerine's.

Do you have the correct solid outer mounts for the cross bar or did you (or PO) replace them with rubber mounts?

If you have the solid mounts, check the sheet metal the cross bar is mounted to and make sure nothing has rusted through. The only way that cross bar can drop is if either one of the mounts failed. That's either the bolt(s) came lose or the metal cracked.

Since your shifter is hitting the top of the hole, either the cross bar moved down or the shifter moved up.

PS: Post some pics of all the mounting points and the firewall area where the shifter exits

Correct solid outer mounts. No signs of cracking or rust even.

I am starting to think the shift rod moved up. The way it bends I am suspecting it did slip a spine. Everything under the engine area looks like it has always looked as far as I can tell. The splines took a little wear and tear when I redid everything a few years ago.

Those look good, how about pictures of the rear transmission mounts?

That looks good too. I think we can rule out any of the mounting points.

This might just be the camera angle, but in your first pictures, it looks like the engine bar is bent.
The long sleeves that have the bolts inside look like they are bent towards the rear of the car.

Did you bottom out and hit something with the cross bar?

Look at the difference in post 12 vs 13. I haven't looked at my cars to see if this is normal but the transmission mounts appear to be at opposite ends of their travel. As though the engine/transmission are sitting cocked in the car?

edit Just realized different angles...

The pic with the speedo drive in it the bolt is more towards the muffler Or rear of the car. The other pic shows the console dust cover and axle, looking forward. It looks like the bolt is towards the rear of the car again. The pics are on their sides, I turned my laptop

Transmission mounts look a little low to me. Could also be the rubber engine mounts. Set the parking brake, start the engine, and have a helper put it in 1st and release the clutch a little while you watch the engine (hatch open). If the engine raises up on one side a couple inches you probably have a bad mount. Not fun to change either.

@Millerwelds

Can you post a pic of where the shift rod bar is contacting the engine bar?
Have you checked the bushing in the shift console? And that the shift coupler at the trans end of the rod is intact to the rod end with bushing?
Helped a guy with a similar probelm but he had the engine swapped end for end. The shift rod way binding against the bar.

Yes it is and has always had that angle to it. The bottom of the bar angles to the rear of the car. There is a large sump (not a tuna can) on the engine that is lower then the bar and I have never caught either on anything. Might have been bent prior to my ownership but always like that since I bought it 12 or so years ago.
