    Need some trans fluid and have two or three options, Nulon, Penrite and hopefully Castrol. I am leaning towards Nulon even though Penrite is cheaper by 5 bucks. I heard Penrite full syn can cause problems. Don't want DX 3 i want full syn or i would just by the best special.

    The Nulon full syn runs sweet in the 4 speed VE Box. It's the Penrite LV that causes problems for me :(
    The FS seems ok but Nulon runs the best!

    I grabbed Nulon, thinking if it wasn't a good choice i can swap it. Only had two options in full syn. Out of three main stores the only full syns available were Penrite and Nulon.

    Strange how this Full Synthetic label has gotten everyone in. There's no such thing in everyday oil as Full Synthetic, it's all based on Mineral Oil and is a load of BS.

    Do some research and if you read between the lines you'll find out that all the oil companies are spinning us with crap regarding synthetics.

    https://en.wikipedia.org/wiki/Synthetic_oil

    Back on topic, what was ever wrong with normal Castrol Dexron 3 in these average GM transmissions that we all have ?

    My old trans tech uses syn trans fluid. It lasts longer than the old DX3. I use it because he uses it. This trans bloke is the best in the state so i trust him to know his stuff.

    Yes. I run the Nulon full syn in my power steering. It's the quietest VE steering you ever didn't hear :) Yes I'm being serious!

    Just jam the cheapest dex3 or type f in it you can find and happy motoring .just going from Dex3 to type f changes the shift properties of the valvebody. Trans fluid blends are the right right amount of slippery for lubrication without causing slippage and being the right viscosity to fill the correct passages at the right speed through the small holes

    What's the difference between dex3 and type f?
    It's funny how little info there seems to be on the net on transmission fluid compared to engine oil.
    And just from my own experience, the first time I serviced my trans and power steering with the Nulon MV Full Syn the difference in the way the car ran was un #$&@ing believable. Absolutely blew me away.

    I'm just gonna stick with what the trans tech put in, which was syn. I have the Nulon now so will use it. I trust the trans tech because he is the best in the state. It's the reason you used to wait up to 4 months to get in. Now you can not even get in because he is so booked out. I have no doubt you blokes running DX3 have no issues but that's not why I asked the question. I was always gonna run syn just the brand i needed to check as i heard Penrite caused problems and was hoping Nulon was going to be ok.
    I know you blokes on JC know most things but I have been given bad advice before from very knowledgeable members, that turned out to not be the best move.

    We use type f cause it has a higher heat rating and faster more positive shift much like b&ms own fluid they sell for crisper shifting

    And a very small state it is indeed which increases the margin for error indeed. ;););)

    I to basically use only Synthetic oils in all my vehicles except in the trans. But in saying that I to have been conned by all these oil companies that are basically modifying mineral oils and calling them synthetics. The more you look into it the more you'll see that marketing plays the biggest part in the greater scheme of things. Here in Australia we have a huge oil industry, but look at Japan and it doesn't exist, yep no pallets of oil in Supercheap stores over there as the oil that's put in the car will still be in it when they piss the vehicle off to the scrap yard and start the process all over again with a new car.

    My mate across the road is sold on Nulon as it has Teflon added into it which isn't new technology by any means. There was a whole cottage industry around many years ago of selling door to door products like "Swipe" and many others that were basically an additive that you added to your oil that contained Teflon which were to fill all the microscopic lows within the metal when machining and create a smooth finish, thus much less friction. They ran cars across Australia with only Swipe in the crankcase to prove that how good the product was and that oil is all wank factor and a huge money making industry. In many ways they were correct but the public at large were so indoctrinated by the oil companies that they break into that market. Thus brands like Nulon decided to mix the two products together and do it that way, the best of both worlds it seems..............and it worked.

    Type F was for Fords which used different specs to many others, thus many GM orientated transmissions used Dexron and then 2,3,4 onwards.

    From Castrol's Website,

    CASTROL TRANSMAX TYPE F

    Designed for use in older Ford vehicles (pre 1982), with the special friction characteristics of Type F fluid. Meets Ford: M2C33-F and M2C-33G specifications.

    Sheesh boys, I wasn't expecting to spark such debate on a simple question. Probably should have known anything lube related goes viral, lol. I'm not saying DX3 wouldn't suffice, just that syn will be better for me as i don't have to get it serviced every 20k. Instead I can wait 40k. I have run syn for years and it has been fine. I don't care if it's an extra $4 a litre. Considering the Y pipe needs to come off each trans service the longer i can wait to service it is a good thing.
    In the engine i use mineral and what ever is the best special at the time. I just try to get an SL rating or higher.

    Hi Losh,

    No furor intended, just passing on some knowledge that I've learnt from being conned by oil companies. They spend millions in their marketing keeping us ill-informed.

    Is it due to your modified exhaust that you have to remove the Y piece ?, as in standard exhaust there's absolutely no issues with encroachment of components.

    There should be more oil threads, particularly transmission fluid threads because part of the problem is nobody talks about trans fluid lol, which makes them uninformed when they walk into the parts store.
    My take on so called Full Synthetic oils and fluids is they are essentially high quality refined oils made from mineral stocks. Or in other words, they're the best thing you will find for $40 a bottle. And I sure ain't paying $80-100 for the real thing because I don't need it.
