well im bookin my baby in for a major service and im not happy with the gearbox oil in it.. i had a heavy oil in it when i first bought it but as posted then it was crunchin when changing down into 4th and sometimes when going in to 4th on the way up if givin it some.. as im aware its the synchros however then i had a lighter oil put in to allow for the synchros to open quicker...

but ive been told to try one of those redline shock treatment's as many people have stated that they help fix that problem..

So after all that bs, my question is what a real good oil to use and or does that redline stuff work and which one.?

any help would be appreciated..

Cheers,

Corey

+ 3 for red line shockproof...

There are three types... heavy, light and superlight from memory...

I used the light one.. as mention above its the blue coloured one.

Expect to pay for it tho.. i think i paid 120 for 1 us gallon... or 3.8 litre in our terms.

yea it does

something about the particles going into the gears making it smoother..

not exactly sure on the technical info behind it

But it came high recommended from a trusted mechanic.

so i put it in, and it is as sweet as ever.

    • Hope you aren't too sore after that one, might take a day or 2 to notice yet and I guess it is a loooooong drive home. On the bright side, tube frame front end is a thing at superlap, right?

    • The chart of front pressure to rear pressure (with one being on the x axis and the other being on the y axis) is not a straight line on a typical proportioning valve. At lower pressures there is a straight line with one slope, and at higher pressures that changes to a lower slope. That creates a bend in the line at that pressure, called the knee point. If you do not change the proportionng as the pressure gets higher, you will suffer excessive pressure (at one end of the car or the other, depending on which way you look at the proportioning action) and then get lockups at that end. The HFM BM57, from my memory of previous discussions, is based on the BM57 from a different car (to a Skyline), with a different requirement for the location of the knee point and the distribution of pressure front to rear, and so is not a good choice for an upgrade on a Skyline. Here's a couple of links to some old posts, one from here, one from elsewhere. A lot of it pertains to adjustable prop valves, but the idea is the same. There are plenty of discussions on here about this issue from al the many years of people wanting a cheap/accessible option. https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/ https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/  
    • Yeah dunno why johhny posted that here with no context, just post on FB/insta bro where he put it up?  Laine had an off at T4 during Thurs prac, he's ok, car is less than perfect, they are done for the weekend, he can fill in the rest. Bando also binned it like 100m up the road.   
    • I feel there must have been a FB/insta post and the weekend did not start well at all I hope everyone is all okay
