    All,
    I have removed my gearbox sump to inspect, clean the pan and replace the gasket, and just because i wanted a look!

    After i removed the sump, 3 ball bearings, 2 springs and a spacer fell out! I replaced my pants and started to have a look.

    Thankfully they seem to be retained by the sump when it is reinstalled and before i fix the new gasket and refill with costly oil, can i run this by you?

    I think the spacer sits in the recess of the sump cover itself, the springs sit on top of these and the ball bearings are held against the recesses on the shafts when you look up into the box.

    If you have done this yourself you will know what i mean!!

    (sorry having problems attaching photos)

    Cheers

    ;) Correct!
    Jumpy little peas..

    One tip though if you refill with synthetic oil. Sonething I didn't know myself.. You NEED to change it after 1 to 2 years. The forks cannot withstand the chemicals of these oils over time. I was explicitly told by the Ferrari specialist to change every 1 to 2 years. Currently using Shell Gear HD 75w90, but I will go over to mineral again since I do not feel any difference in shifting and I have the 2nd gear issue when cold like most Mondials.

    Good info thanks mvt. I have opted to go for Millers LS 75w90. Not too cheap, more reassuringly expensive!
    Cheers

    Hey MvT, ever used Redline oil? We had terrible issues with the X19 going into reverse and also feeling very notchy overall. Then we changed to Redline oil, Increadible!! I would never have believed an oil could make a change such as it did. It feels like the gearbox was rebuilt, gearshifts are almost telepathic wow!
    One snag the X19 does not have a limited slip diff and the Ferrari does.
    Any thoughts?
    Regards Bell

    Hey Bell,

    When I changed my gear oil a couple of years ago, I used 4 quarts of Redline 75w90 NS and 1 quart of Redline 75w90. I followed recommendations of some of the 3X8 guys on the Redline. I use Redline 5W40 for motor oil in the Mondial. I'm impressed by their product generally and so thought I'd give the gear oil a try. The logic behind the decision to use 4 quarts of NS and one quart of regular is that the NS is not ideal for limited-slip differentials. I've read (though never experienced first-hand) that some guys get differential chatter in a tight corner without the friction modifiers that are in the regular 75w90. They suggested though, that if you use all regular 75w90, the second gear synchro stiffness is worse.

    Hi Antwan, sorry Matey, I don't want to hijack your thread but this might be interesting to you also.

    Mac, I get limited slip diff chatter also and that is using the gear oil that Ferrari recommend, surprisingly it is not an LSD oil at all. I also noticed that all the dealership 328 and 308 cars make the same noise when turning slowly. Could Ferrari be using the wrong oil?

    Back to the original topics.

    Three balls, springs, and spacers. They go into the holes at the edge of the transmission. There are pictures of where they stack up. Search and you will find, it's a common topic.

    Interesting what Jon says on the 75w90! Bell I've never used Redline. Read about it, but I get nuts all info on oil recommendations. I went to the more expensive Shell stuff (yeah I know. want to keep the TAX domestic;-), but it is not giving me what I want/expect. And only using an expensive oil to change every year I find grazy. Perhaps I should give a try on Redline, which Redline as I see 21 choices of Redline Transmission oil :eek:

    Hey Bell no worries. Just got in from swinging spinners in the garage. Reconnecting the gear linkage and setting the length, position.

    Redline although it has great reviews is very expensive. The oil I have gone with seems, on the face of it anyway, to be a quality oil at a more reasonable rate. Have you noticed also that the redline stuff seems to be sold at exactly the same price wherever you go for it.

    I'll give it a few months with this.

    Ahh, really! After reading all the threads on redline, I just had the gear oil changed to all NS. Had never seen that it was not appropriate for the complete replacement due to the lsd. It is the type oil recommended by the redline website. This is the first I've seen that it will cause some "chatter" problems. Soo, what does it mean?

    Hello Gerald

    I just replaced the gearbox oil in my 85 QV with Redline. It made a huge difference. There was no longer any stiffness in shifting from 1st to 2nd. None at all. Even when the engine is cold. Previously, a huge amount of effort was required.

    My car has 65000 miles on it, and now the transmission shifts very smoothly.

    Here's exactly what I ordered: Red Line Synthetic Oil - Gear Oil for Manual Transmissions - 75W90 NS GL-5 Gear Oil

    Good luck

    Sid

    Hi Sid,
    Thanks for the reassurance about your result with using all NS. It is what I expect to find when I pick up my 85 QV tomorrow. I only noted my surprise to some posts regarding not completely replacing the gear oil with all NS.

    I do look forward to seeing if 2nd gear engages smoothly the first time when pulling away from the garage and for smoother gear changes overall. I'll also be attentive to see if, when and where "chattering" occurs and if it is at all bothersome. As I am far more a grand tourer than a boy racer, perhaps it will not be noticeable.

    Gerald

    Hi Gerald

    I didn't believe the hype about the redline oil. However, since I was going to change it anyway, I decided to give it a try.

    It really did work. And still works - although I only have about 200 miles on the car since I changed the fluids.

    Also - no gearbox chatter. The only chatter I have is coming from my A/C compressor - I think the compressor bearings are going bad. That will be my next job.

    Sid
