1983 QV - Cannot select 1st Gear and Reverse

    Usually after a run it is difficult to select reverse gear from 1st as I manoeuvre the car to get it back in the garage. Reverse gear feels notchy and it needs a bit of a slow shove. I usually leave the car parked in first gear. This morning when I started the car I had difficulty, at first, getting it out of 1st gear. It was very stiff then it felt like something maybe broke and now the gear stick moves scarily easily into 1st or Reverse but when I let out the clutch nothing happens.

    It seems that 2nd to 5th gears are still operating normally.

    I removed the rear ashtray and I can see that when I move the gear stick the selector shaft moves in and out and rotates so the problem must be rearwards from that point.

    Any ideas what might be causing this? How bad could this be? Could it be something to do with the linkages or is it more likely to be a problem inside the gearbox?

    The reason I ask is that I have a choice of independent Ferrari engineers near me. One about 20 miles from home the other about 80 miles from here. I would trust the local guys to repair the selector linkages but I would rather use the more distant guys if the gearbox needs to be rebuilt.

    Do you think it would be ok to drive the car to either garage or should I get it towed to avoid any further damage?

    Can you remove the gearbox from a 3.0 QV without removing the engine?

    Thanks for your help, any advice is greatly appreciated.

    It sounds like a misalignment of 1st/R forks inside the gearbox. Maybe one of them is loose on the linkage shaft. Better take a look at it to see what is going on.

    I guess it is similar gearbox as the 328, so it might be an easy fix just dropping the pan, and given that nothing is broken.

    Hi Conan. Thanks for your reply. If I have managed to break the selector fork could that be repaired without removing the gearbox?

    Not sure. You need to slide the shaft out enough to remove the fork, if it is the selector fork or the synchro sleeve fork. Hopefully, it is only a misalignment or loose fork. In neutral, it should look like this, the selector forks should almost touch eachother and line up exactly.

    Someone correct me, but I do not think removing the shaft can be done without lifting or pulling the engine.

    But do not do it first, check what it looks like inside the gearbox first.

    You don't need to lift or drop the engine to remove the shaft. I would start with the followings:
    • Remove the center console and go under the car by the shift shaft to inspect both bushings (Table 33, Item 28 below) in the shift shaft linkage for any play in them.
    • If they're good, the next thing to do is drain the gearbox oil and drop the pan.
    • Inspect the folk for proper alignment. Then have someone in the car shift thru all gears while you observe the alignment and movement of the fork thru the gears. Refer to my video on YouTube (link below)
    Hope this helps.

    I had the same issue at one point and all we needed to do is drop the pan and re-tighten the selector in the correct position. Then please don't forget to refill the gearbox oil :D

    And make sure the synchro sleeve fork, detent ball and selector fork line up well to allow the gear shifter to line up well in the gate. It is not too difficult, but may take some time to get it in optimal positions.

    You ultimately want to hear the R and 1st exit with a click regardless of how close you try to pass the gate cut-out to 2nd or 3rd, if this makes sense.

    At 40 years old, you would expect the bushings (2x) to need replacement. The one under the shifter housing is really hard to access. In the US, this whole thing would run $1,000.

    Good news. I got the car back yesterday. They replaced the bushes in the gearbox linkage. All the spares were available and cheap. No drama. They had to remove the gear selector fork from inside the gearbox which meant they had to replace the gearbox oil. Apparently the oil was in a really bad state so it's probably just as well this happened, it has been on my 'to do list' for quite a while. And with a new gasket, there might even be a few less drops of unidentified liquid under the car :)

    The linkage is often an issue :) I love the color of your Mondial Mauro, never seen it in real life! Were in or region in Italy you reside? We often are in Regio Emilia. Perhaps we can catch up one time it's always nice to meet other Modial owners.

    Hi MvT. The colour is Azzurro Metallico. The car was yellow when I bought her but this is the original colour. If I'd bought the car new in 1983 I wouldn't have chosen this colour but I am very pleased with it now. We live near the small town of Bagni di Lucca. Just the other side of the mountain from Maranello. It would be great to meet up. :)
