    Transmission gearbox leaking...

    Finally found the culprit that causes a stiff gear linkage after a hot run.

    The forkin’ transmission is leaking. Changed the tranny oil two years ago and I think there ain’t much left. Nice old and enlarging spot on the gravel under the tranny. I never noticed before.

    So I’m gunna put new Redline MT-90 and this stuff, into the tranny and wait and see.

    This Wynn’s product (I purchased two), is unavailable in Oz (I can’t find any), so this is from Europe.

    I’m also going to apply a line of metal paste to the bottom join.


    Wish me luck. I’ll post later.

    I'd be doing the job properly if it were me. When i say 'properly', i mean remove the gearbox, disassemble and reseal the casing.

    External patches and stop leak (thickening additives) are bandaids and with a car that is in such nice original condition it would be almost sacrilege to just whack some bog on the outside of the box and put some sawdust inside.

    I doubt it's coming from the join. My money is on of the seals: driveshaft, inputshaft, selector rod.

    Penrite 85w-140 if you want to gamble with a thicker oil - I rate it

    It does happen, but those other are definitely more likely.

    It is the join. Confirmed.

    As I do only 2,000 klicks a year now, (with 135,000 on the odo after 25 years) not sure if I wanna spend to professionally fix it at this time, even though I like it purrrfect. Will check leakage after fix.

    I'll give this a go and advise.

    bty: The Red Jett will be for sale in 2022. That is after 30 years of a one owner's seductive affair with it.

    Hang in there.

    Phil.

    Oh what have you done to me Cozzm0?

    OK, you put me to shame. The leak has got worse over the last four years. Huh, I already knew about it.

    OK, who ever get's the Red Jett in five years better remember this.

    I'll get a quote from a reputable garage, most likely go Von Bibra Nissan Gold Coast. Lots of experience.

    Thanks Pal, you prolly cost me $600.00 bucks!

    K'mon Phil, i thought you were a DIY guy ?! You can pop the case off with the box still in the car, but it makes the whole job a lot harder.

    Ah-hem… I was a DIY guy. Now gettin' long in the tooth and sick of skinned knuckles and bruised arms. I wish I had a hoist. That would be lotto for me.

    No, I'm gently rockin' the Jett towards its 30th birthday and then seeing who wants to look after it.

    I am perplexed that there are no PURPOSE manual gearbox stop leaks in Oz.
    I gave the Wynn's option a miss… Postage - was 40 quid from Europe.
    So looking at this one. Check it out:

    Note that after the words, Blue Devil, are 'do it yourself'… Ah, all my life is just a circle…
    The reviews, on Amazon, were all avg. 4 stars.

    Looks the goods…

    Well, tranny oil changed today. As this leak has been, I think, causing my linkage to tighten after a hot uphill run.

    However, I got about three litres out and in good colour. Minute filings around the sump plug magnet. Nought to worry about there.

    Replaced 3.6 litres of Redline MT-90, along with 120 mill of BlueDevil transmission sealer.
    http://store.gobdp.com/transmission-sealer-00236/

    Took the Red Jett for a hot run to Canungra (Gold Coast Hinterland) and back. All is well.

    However, I think the linkage stiffening, might be because I removed the heat shield, which would sit below the shifter and cook it up.
    Wrapped that piece of pipe (was once where a feline roamed), with header wrap.

    Let's see now...

    It was a weight reduction thing I did. Spoke to Colin Chapman about it...

    OK, verdict is now in. The BlueDevil product has fixed the tranny leak. No more there.

    This stuff was like water and clear. I can recommend it. Can only be sourced from the US.
