To minimize the spillage when removing the cooler... find two bolts to plug up the hoses with :D

Works a charm...

Remember, DO NOT EMPTY THE OIL INTO THE DRAIN! How would you like it if someone poured oil in your water bottle :P

i run mine with a inline thermostat similar to this: http://www.ebay.com.au/itm/Improved-Racing-High-Flow-Transmission-Fluid-Thermostat-160-F-3-8-Hose-Barb-/131110824589?pt=Motors_Car_Truck_Parts_Acc

So, how do you fill the oil up again? I take it there is a dipstick to check the level?

If you pull the top hose off and run the motor to empty the trans, wouldn't the cooler itself still be full of oil (and it would subsequently go everywhere)?

Sorry for all the questions.

You fill the tranny through the dipstick tube.

I just pissed oil overwhere. Removed the hoe here and there and tried to get all i could. First i drained the sump though.

Also, i didnt jack my car up as i didnt want it on an angle to drain the oil.

I got a funnel and some hose, put them together, and stuck the hose in the dipstick tube. That is my dodgy assed method.

Alex, I've never totaly drained an auto with out taking converter out. Were u able 2 do that or r u only draining out what is pan and cooler lines. 2lt. doesn't sound much 4 an auto box. I want drain completely if poss. to fill with fresh fluid. I recon the auto would love that and may also sharpen changes a bit!. Cheers.

I removed the pan, you get about 1 to 2 litres, replace this with the same amount as you get out, also clean the filter while the pan is off, mine was filthy. Then take the line off the cooler thats coming from the box, start the car and pump out and measure 1 litre of oil, turn the car off, then replace it, keep repeating this until the oil looks clean.

Took about 8 litres for the oil to become clean.

From what i understand they hold around 12 litres all up.

that's clever... cheers for that

How about a variation... take the cooler inlet hose off, dunk it in a bucket marked 'old transmission fluid', and put this down low, say on the ground. Then, attach a length of temporary hose to the inlet of the cooler, and hold this in your new oil container.

...or, to make things easier on the trans oil pump, you could arrange a gravity-fed setup of a clear plastic bottle inverted, with the hose in the lid. That way you can even meter the level going in... I've never tried this but thought it could work?

Hey guys it seems that nobody has asked yet, but is the trans cooler upgrade as relevent to series 2's? They appear to have a much more substantial cooler than the S1's simple "finned loop" - looks like a 'proper' radiator (same style as radiator), don't know my tube & fin from my plate & bar tho. Just wondered if the tiptronic needs something bigger than that?

I have finally fitted the large (Davies Craig) auto transmission cooler to the Stagea. The part number I chose was 678 which is the largest universal (280 X 216 X 19) I could find with 3/8" fittings. The catalogue specifies for engines "4.2 litres and over"

I will post up some pictures of the installation tomorrow. :D

For Kiwi readers this unit is available (by mail order if necessary) from Silverdale radiators for $149 +postage (saw it on Trade Me).

Go into Supercheap and see if the 678 is bigger than yours. If not I read in a US car magazine a suggestion to go to the scrap merchant and get a huge heat exchanger out of an aircond unit basically for the price of the scrap value. Then you have to make up your own mounts and buy some hoses.

Fitted a PWR cooler last friday. Was a rather easy task. I used the same bracket and just drilled an extra hole in the cooler and bracket the same as SK did.

Felt the cooler today after driving to work-30 min freeway drive and it was warm to touch but not hot at all.

Also looks mean from the front cos intercooler is down low then in the grill on the left you can just see the trans cooler :)

Hi all,

Just thought I'd share that I visited MV auto's in Adelaide about my standard (as far as I know) trans cooler on my S2. It is pretty large, a lot more substantial than the S1's and possibly even larger than the Davies Craig jobbie in those pictures that SK fitted. MV's advice was that it was a good size and didn't require upgrading; only that it would need relocating if I was to fit an intercooler. Which I will do eventually... and a high-stall convertor is sounding more like a good idea as my GCG hi-flow turbo is lacking in stall-launches compared to the stock turbo.

      Strange issue RB25DET wont start

      By jtha7 · Posted

      Ps i found the below forum and it seems to be the same scenario Im dealing with. Going to check my ECU coolant temp wire tomorrow    From NICOclub forum: s1 RB25det flooding at start up Thu Apr 11, 2013 7:23 am I am completely lost on this. Car ran perfectly fine when I parked it at the end of the year. I took the engine out and painted the engine bay, and put a fuel cell with an inline walbro 255 instead of the in tank unit I had last year. After reinstalling everything, the engine floods when the fuel pump primes. if i pull the fuel pump fuse it'll start, and as soon as I put the fuse back in it starts running ridiculously rich. I checked the tps voltage, and its fine. Cleaned the maf as it had some dust from sitting on a shelf all winter, fuel pressure is correct while running, but wont fire until there is less than 5psi in the lines. The fuel lines are run correctly. I have found a few threads with the same problem but no actual explanation of what fixed it, the threads just ended. Any help would be appreciated.

I found the problem though. There was a break in one of the ecu coolant temp sensor wires. Once it was repaired it fired right up with no problems. I would have never thought a non working coolant temp sensor would have caused such an issue.

      Hi sorry late reply I didnt get a chance to take any pics (my mechanics on the other side of the city) but the plugs were fouled from being too rich. I noticed the MAF wasn't genuine, so I replaced it with a genuine green label unit. I also swapped in a different ignitor, but the issue remains. I've narrowed it down a bit now: - If I unplug and reconnect the fuel lines and install fresh spark plugs, the car starts right up and runs perfectly. Took it around the block with no issues - As soon as I shut it off and try to restart, it won't start again - Fuel pressure while cranking is steady around 40 psi, injectors have good spray, return line is clear, and the FPR vacuum is working. It just seems like it's getting flooded after the first start I unplugged coolant sensors to see if its related to ECU flooding but that didnt make a difference. Im thinking its related to this because this issue only started happening after fixing coolant leaks and replacing the bottom part of the stock manifolds coolant pipe. My mechanic took off the inlet to get to get to do these repairs. My mechanics actually just an old mate who's retired now so ill be taking it to a different mechanic who i know has exp with RBs to see if they find anything. If you have any ideas please send em lll give it a try. Ive tried other things like swapping the injectors, fuel rail, different fuel pressure regs, different ignitor, spark plugs, comp test and MAF but the same issue persists.

      My return flow is custom and puts the return behind the reo, instead of at the bottom. All my core is in the air flow, rather than losing some of it up behind the reo. I realise that the core really acts more as a spiky heatsink than as a constant rate heat exchanger, and that therefore size is important.... but mine fits everything I needed and wanted without having to cut anything, and that's worth something too. And there won't be a hot patch of core up behind the reo after every hit, releasing heat back into the intake air.

      There is a really fun solution to this problem, buy a Haltech (or ECU of your choice) and put the MAF in the bin.  I'm assuming your going to want more power in future, so you'll need to get the ECU at some stage. I'd put the new MAF money towards the new ECU.
