    Just finished a belt job and started it up.
    The good news is that the engine is running.
    The bad news is when I put the car in reverse it moves forwards not backwards.
    I disconnected the shifter bar under the car but nothing else. It was a pain to connect and adjust it but I must have disturbed the gears while reconnecting?
    Any help would be much appreciated.
    Any forums that address this issue?
    I have a difficult time searching and finding issues like these in the titles.

    I don't think there are any issues with your gears. My bet is that you have an issue with the linkage. You might want to go back and recheck your install of the linkage and its adjustment.

    OK
    That is what my friend said too.
    I'll look at it again

    Simply a case of the shift rod being connected out of synch with the gear selector. You have to manually feel for neutral now at the shift block and re install the shifter bar. It’s not a difficult job.

    The way I normally reinstall the shift rod is to
    1. Free off the threaded adjuster and lock nuts, (re)apply anti-seize
    2. Make sure the gearbox is in neutral
    3. Thread the shift rod through the x-member & sump loop and reattach the shift linkage at gearstick end
    4. Check the gearstick is sitting in the neutral position
    5. Reattach the linkage at gearbox end and check again that the gear stick is still sitting in the neutral position - if not, make a coarse adjustment to the threaded adjuster
    6. Select the gears in the car from Reverse to 6th to check they all select
    7. Fine-tune the adjustment with the threaded adjuster on the rod to ensure the gearstick does not bind on the shift gate preventing the gears from fully engaging at the end of the stroke.

    Note that the adjuster on the shift rod only adjusts the gearstick fore & aft position, not side to side.

    This process has always worked for me.

    If you are still having a problem you will need to check that the attachment points at each end have not somehow become twisted or if there is a problem elsewhere in the mechanism.

    How do you know or set the gearbox in neutral with no shift linkage on? Just do not park near a cliff!

    Well, I try to always make sure to put it in neutral before I remove the shaft,

    if you have the shaft off you can move the selector rod by hand, or with grips.

    When I removed the shaft I put it in third and by the time I got the threaded link removed it was in fourth.

    Just an update on the threaded adjuster and shift rod.
    I tried to adjust it twice and was unsuccessful. Then went to a Ferrari mechanic for help. He and I were able to fine tune the threaded adjuster so all gears work including reverse. I couldn't have done it myself. Very finicky and the slightest adjustment changes everything. Make sure that the lock nuts are firmly tightened when you get it right otherwise even a slight change in the threaded adjuster and it will throw it all out of synch.

    Have you looked at replacing the bushing in the shifter box? These normally wear and will cause some vibration noise in the cabin with the shifter touching the gate.

    FYI
    Here is an awesome video showing how to disassemble and grease the shifter.

    Gearbox has a detent holding it in neutral. Move it to that position.
    Shifter has a centering spring. Move it to that position.
    Attach to each other. Done.

    Well no. There are rotational and length adjustments.

    It literally is as simple as that. I have never had any issues doing it that way. I think the problem is that some people twist the rod as they are tightening the lock nuts and messing up the alignment.

    Well that would require disassembling it the wrong way to start with.

    If you are working off the detents for the angular alignment then the adjuster screw only adjusts fore/aft. I suppose if you are ham-fisted, then yes, you can also misalign the stick to the gearbox plunger.

    "Note that the adjuster on the shift rod only adjusts the gearstick fore & aft position, not side to side."

    Your statement, not mine.

    Hahaha. Are you having a slow day? Or studying law?

    I was trying to say keep everything in alignment rotationally & considering this a chat room and not a court of law it’s perfectly fine.

    you are not the only person who knows how these cars work, maybe that bothers you, but it shouldn’t. You are still respected around here by a few people, despite your prickly attitude.

    If you provide incorrect information that confuses the issue and I correct it don't blame me.

    Just based on the fact I ignore well over 99% of the posts here strongly suggest it is you who seems to have issues.

    I just had a slightly different problem.
    Had a good drive yesterday, the car behaved well. Went to take it out for a tun before the weather but the car would not reverse- when I put it n reverse the car moved forward. This really weirded me out. Fine yesterday- no reverse today.
    I let the car idle for a while in neuteral to warm up the transmission and while i was waiting took the gate off. the spacer under the dash assembly is broken. I moeved a piece that had fallen immediately to the left of the shifter and it worked. I put it back together with the broken spacer as best i could and it works fine now.

    I'll orer up a new spacer: https://www.ricambiamerica.com/car-diagrams/ferrari/v6-v8/355-group/f355-m5-2-1996/outside-gearbox-controls/159389-gasket.html

    Update- new spacer installed - part number found on the forum (Part number help | FerrariChat) easy job- all good.
    For whatever it may be worth, the guy at Ricambi America told me this was a common 355 problem.
