After i've connected the cooler, i'm thinking of running it with the outlet into a bucket for a few seconds to flush it just in case. Is there any risk with doing that?

Will it flow in neutral or will it need to be in drive?

It will flow in neutral and FAST. 

Make sure you add some weight to the hose so it wont spit/fly everywhere, trust me, this is from experienced :). One crank/idle for 2-5 seconds and i could easily get around 0.5ltr or more out.

What colour is your ATF? If it is dark brown rather than bright red consider using the opportunity to change the fluid (which you cannot do by draining or dropping the sump). You may need 12L or so to do this.

I've just done the 4lts in the pan a couple of times, so it shouldn't be too bad but i havent checked in a while. I had assumed that pumping it all out would be risky for any running that occurred after the last of the fluid was out. Do you think pumping it all out would be safe?

What I do is pump out about 2L turn it off and add 2L down the dipstick and repeat until the fluid comes out clean.

Did that and it worked well. The fluid didnt look great so i pushed 8 litres through. Now crossing fingers to see if its enough to stop the overheating.

How easy is it to install a Trans cooler? I need to get one for mine.

Easy as. There is a tutorial in the DIY section above. Its for a C34 but much the same.

      RB20DE NEO smallbox clutch.

      By Kapr · Posted

      For once a good news  It needed to be adjusted by that one nut and it is ok  At least something was easy But thank you very much for help. But a small issue is now(gearbox) that when the car is stationary you can hear "clinking" from gearbox so some of the bearing is 100% not that happy... It goes away once you push clutch so it is 100% gearbox. Just if you know...what that bearing could be? It sounding like "spun bearing" but it is louder.

      Yeah, that's fine**. But the numbers you came up with are just wrong. Try it for yourself. Put in any voltage from the possible range and see what result you get. You get nonsense. ** When I say "fine", I mean, it's still shit. The very simple linear formula (slope & intercept) is shit for a sensor with a non-linear response. This is the curve, from your data above. Look at the CURVE! It's only really linear between about 30 and 90 °C. And if you used only that range to define a curve, it would be great. But you would go more and more wrong as you went to higher temps. And that is why the slope & intercept found when you use 50 and 150 as the end points is so bad halfway between those points. The real curve is a long way below the linear curve which just zips straight between the end points, like this one. You could probably use the same slope and a lower intercept, to move that straight line down, and spread the error out. But you would 5-10°C off in a lot of places. You'd need to say what temperature range you really wanted to be most right - say, 100 to 130, and plop the line closest to teh real curve in that region, which would make it quite wrong down at the lower temperatures. Let me just say that HPTuners are not being realistic in only allowing for a simple linear curve.

      I feel I should re-iterate. The above picture is the only option available in the software and the blurb from HP Tuners I quoted earlier is the only way to add data to it and that's the description they offer as to how to figure it out. The only fields available is the blank box after (Input/ ) and the box right before = Output. Those are the only numbers that can be entered.

      No, your formula is arse backwards. Mine is totally different to yours, and is the one I said was bang on at 50 and 150. I'll put your data into Excel (actually it already is, chart it and fit a linear fit to it, aiming to make it evenly wrong across the whole span. But not now. Other things to do first.

      God damnit. The only option I actually have in the software is the one that is screenshotted. I am glad that I at least got it right... for those two points. Would it actually change anything if I chose/used 80C and 120C as the two points instead? My brain wants to imagine the formula put into HPtuners would be the same equation, otherwise none of this makes sense to me, unless: 1) The formula you put into VCM Scanner/HPTuners is always linear 2) The two points/input pairs are only arbitrary to choose (as the documentation implies) IF the actual scaling of the sensor is linear. then 3) If the scaling is not linear, the two points you choose matter a great deal, because the formula will draw a line between those two points only.
