What gearbox oil are you using?

Could it be due to the weather cooling and the oil thickening?

How old is your slave cylinder? (underneath on driver side of gearbox)

I fitted a new slave cylinder, fresh clutch fluid and had it all bled and it was like I just had a brand new clutch fitted, that's how big of difference it made.

If you havent got it already, try putting synthetic oil in your gearbox. Synthetic oils perform much better a low (and high) temperatures than minerals. I havent had any sticking since i switched to redline light shockproof in my tired old box. Shockproof is not suitable for a recently rebuilt box tho.

gearbox was built from scratch 11 months ago. i'l change the gearbox fluid and clutch fluid n see how it all goes

11months is nothing. It should still be perfectly fine unless your master or slave cylinder is bleeding off a little resulting in poor travel.

Not saying this is the case in your circumstance but I had a gearbox rebuilt for $1200 including in/out labour (VS 5ltr 5speed) some years ago as first gear was popping out and I didn't have the time to do it myself.

I requested everything to be replaced, all bearings and syncro's as the box had a little layshaft rattle. (I've rebuilt box's before I know what sounds are coming from where)

Upon receiving the gearbox it still had the layshaft rattle; I questioned the people and they told me it was a load of crap and couldn't hear the layshaft rattle when it was as clear as daylight. He also told me they send the gearbox's off to a specialist to rebuild. So that was that.

A few months later at a party I met a bloke and we got talking. He mentioned they do the gearbox work for the mechanical shop that I had do mine and that he remembers doing a vs 5ltr 5speed gearbox box BUT it wasn't a full rebuild; it was only to fix the first gear (he said it was just a pin that dropped out) and replace syncro's. I return to the work shop and find they have gone bust...... :)

So screwed.

90% sure it's your gearbox oil guys. I got some Motul gearbox oil put in mine and I started having the very same problem. Switched to Red Line Light Weight Shock Proof and I couldn't be happier. No problems now whatsoever. It's not recommended for newer boxes though.

Talk to a mechanic that works mainly on imports and they all recommend it.

Talk to a 'gearbox/clutch specialist mechanic' and they tell you it's a not as good as everyone thinks. I had 1 good local specialist mechanic show me the internals of 2 gearboxes that he was working on. The gearbox that had Castrol oil was nice and clean, the redline gearbox looked like someone had filled it with grease, not oil.

Each to their own I guess.

    • The oil pressure sensor for logging, does it happen to be the one that was slowly breaking out of the oil block? If it is,I would be ignoring your logs. You had a leak at the sensor which would mean it can't read accurately. It's a small hole at the sensor, and you had a small hole just before it, meaning you could have lost significant pressure reading.   As for brakes, if it's just fluid getting old, you won't necessarily end up with air sitting in the line. Bleed a shit tonne of fluid through so you effectively replace it and go again. Oh and, pay close attention to the pressure gauge while on track!
    • I don't know it is due to that. It could just be due to load on track being more than a dyno. But it would be nice to rule it out. We're talking a fraction of a second of pulling ~1 degree of timing. So it's not a lot, but I'd rather it be 0... Thicker oil isn't really a "bandaid" if it's oil that is going to run at 125C, is it? It will be thicker at 100 and thus at 125, where the 40 weight may not be as thick as one may like for that use. I already have a big pump that has been ported. They (They in this instance being the guy that built my heads) port them so they flow more at lower RPM but have a bypass spring that I believe is ~70psi. I have seen 70psi of oil pressure up top in the past, before I knew I had this leak. I have a 25 row oil cooler that takes up all the space in the driver side guard. It is interesting that GM themselves recommend 0-30 oil for their Vette applications. Unless you take it to the track where the official word is to put 20-50w oil in there, then take that back out after your track day is done and return to 0-30.
    • Nice, looks great. Nice work getting the factory parts also. Never know when you'll need them.
    • Thanks @jtha7 I will have a look around tomorrow but it is a prick of a spot. These are some photos i tried taking 
    • I take it that the knock retard is from bearings tapping a little tune? Thicker oil is a fragile bandaid. You need a much bigger oil cooler and probably the bigger pump being discussed.
