Transmission Cooler

[satanic]

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

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

[Nightcrawler]

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.

Looking forward to getting greasy! :lol:

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.

[AlexCim]

well, i removed the drain plug in the sump, so i assumed it was the same as a oil sump/change...??

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.

holy crap, well for 60$ for 4L of castrol Transmax Z ill wait until i put in the built auto to do a full flush.

[neostagea]

just a quick one to all those after trans coolers i have just had some PWR coolers come into Supercheap Auto that are priced at the same as our generic one $85 for one that is rated for a V8. If you are after one and have trouble getting hold of one PM me and i will get one for you

cheers

DC coolers are PWR coolers

Pull off the little DC sticker, its a PWR stamped brand there

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.

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.

Just upgraded to an arc trans cooler but after driving its really hot to touch! Is this normal? cause I never checked the standard one to see if it was hot to touch after use.

[chook]

yes, they generate a lot of heat, even when idling, thats normal.

[kidafa]

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

i still dont have one, my trans is waiting on gasket and filter before i can service it(getting genuine nissan brought in) i have a shit kit, and my fluid is as new, over 12months and 30k km on!

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.
