Gregk Posted 1August, 2016 Report Share Posted 1August, 2016 Hi guys. I took a risk and bought a non running 1980 928. Long story short, we have found the transmission fluid to be milky pink. From what I can gather, this means coolant/water has made its way from the radiator into the transmission. Again, I heard this is fatal for the 3 speed auto? Because of the water based glues used in the transmission?Can anyone confirm this?I dropped the fluid out tonight and found no pieces of anything in it.Would like to hear your thoughts.Cheers,Greg Link to comment Share on other sites More sharing options...
XLR8 Posted 1August, 2016 Report Share Posted 1August, 2016 Greg, I am sure the boys from Buchanan Automotive will chime in soon. They know 928s better than anyone.I hope it's a simple as fixing that rad/transmission cooler, filling both up and giving her a go ...Worst case is a trans from a wrecker .... better than needing a new engine, or finding oodles of rust.

tazzieman Posted 1August, 2016 Report Share Posted 1August, 2016 Depends how long it's been like that. Mine was caught in time , flushed out and all is good. YMMV.The rad coolers fail from time to time and a separate trans cooler is the best insurance. Link to comment Share on other sites More sharing options...
Gregk Posted 1August, 2016 Author Report Share Posted 1August, 2016 Thanks xlr8. We actually got it running last week and while it was a bit rough to start with, it settled nicely and sounded pretty good. That's when we decided to change all the fluids and found the strawberry milkshake ! Thanks Tazzieman. That sounds encouraging. I was told it hadn't been driven for over 7 years and not started for 2 years. Link to comment Share on other sites More sharing options...
Buchanan Automotive Posted 1August, 2016 Report Share Posted 1August, 2016 Water/coolant in any auto trans from any manufacturer from any country made by man on this planet is not good , all you can do is the logical }A ) get rid of the auto oil cooler hoses going to the radiator heat exchanger & install a stand alone auto trans oil cooler in behind the grille & seal off the heat exchanger outlets , naturally if the radiator is that old ( 36 years old ) , then a new rad at some stage will be needed B ) flush out the auto trans with lots of new auto fluidC ) install a new auto oil filter & new auto oilD ) road test ( if it gets that far ) and go from there Note } Radiators with auto trans oil heat exchangers have been an issue in Holdens , Fords ,Valiant's , Toyota's , Volvo's , Mercs , BMW's, Datsun's etc etc etc etc since I was a first year apprentice in 1972 & yes I have been seeing this for all that time The nice thing about last century Auto Transmissions is that ( MOST / NOT all ) are repairable where as MOST in this century are NOT repairable Link to comment Share on other sites More sharing options...
edgy Posted 2August, 2016 Report Share Posted 2August, 2016 On a side note, that is a GREAT looking example you've got yourself. Link to comment Share on other sites More sharing options...
Gregk Posted 3August, 2016 Author Report Share Posted 3August, 2016 Thanks for the reply Buchanan...already underway.Thanks Edgy. It has just 130kms on the clock and looks like it has rarely been outside despite it's radiator/transmission issues. Link to comment Share on other sites More sharing options...
ANF Posted 3August, 2016 Report Share Posted 3August, 2016 Good luck with the fix, I am just going through same, fitting an ext cooler, not for same reasons though. My rad was leaking and replacement does not have trans cooler.Post up some more pics, it does look nice.cheers Link to comment Share on other sites More sharing options...
Gregk Posted 5August, 2016 Author Report Share Posted 5August, 2016 Ok. Here is more of the story. The fuel had turned to black glue ! I have never seen anything like it. We pulled out the fuel pump and filter and black glue oozed slowly everywhere. So we ordered a new filter and second hand pump. Unfortunately the second hand pump didn't work either which added to the confusion. We pulled out the fuel sender, and long story short could see that the tank had to come out to have any chance of cleaning it properly. If you zoom in on that photo, you can see an insane amount of dirt that fell out with the tank. It was 2-3 inches thick in places, especially around the fuel filler area. So the tank was scrubbed clean and re installed and with a NEW fuel pump we finally got it started. Unfortunately with alot of oil deposited and a bit of corrosion hampering conduction, the alternator shorted and started to smoke melting all the wire insulation! So out comes the alternator, re insulated, checked and re installed.By this stage the car had stopped spitting stuff out the exhaust and was running and idling nicely.Thats when we decided to re new all the fluids. First the engine oil which looked pretty good thankfully.Next we flushed the radiator. Unfortunately by flushing it, we moved all the corrosion that was stopping it leaking and it started leaking like a sieve! Link to comment Share on other sites More sharing options...

90sF1Kid Posted 5August, 2016 Report Share Posted 5August, 2016 It looks like your well on top of it, thus far. Fingers crossed there's nothing too major to unearth later on. Link to comment Share on other sites More sharing options...
Gregk Posted 5August, 2016 Author Report Share Posted 5August, 2016 So out comes the radiator and in the process we find the strawberry milkshake transmission fluid.So here we are, waiting to buy a new radiator (any suggestions?). I've cleaned away all the strawberry milk and waiting for the radiator before adding / flushing new transmission fluid.The rest of the car looks pretty good, brakes are ok, engine seems ok, interior doesn't need any work, so fingers crossed ?

Ozvino Posted 5August, 2016 Report Share Posted 5August, 2016 If you want a genuine unit email Roger Tyson at 928sRus in the USA. The air freight won't be as scary as you think, Roger gets good rates. Please check, check, check, check and double check all of the fuel lines in the car they are likely cracked and very high risk of leakage and thus fireCar looks fantastic. Good on you for saving it Dave Link to comment Share on other sites More sharing options...
ANF Posted 5August, 2016 Report Share Posted 5August, 2016 Go to your local radiator place, should be about $1000 for a new one, 928sRus was $600 I think from memory, by the time you convert to aus $ and add freight will be over $1000. PWR is aus also make them, price buried in my emails somewhere, check when next on my pc if you likecheers Link to comment Share on other sites More sharing options...
Ozvino Posted 5August, 2016 Report Share Posted 5August, 2016 be careful with the aftermarkets is my suggestion - but dont dismiss them Link to comment Share on other sites More sharing options...
Gregk Posted 6August, 2016 Author Report Share Posted 6August, 2016 Thanks guys.ANF, I'll call PWR thanks.And yes, I've heard how careful I have to be with the fuel lines! Link to comment Share on other sites More sharing options...
Gregk Posted 15August, 2016 Author Report Share Posted 15August, 2016 Well after much deliberation I ended up with a locally made dual oil cooling radiator just to get it running. I think long term, I will opt to bypass the oil cooler and get an independent transmission cooler from PWR. Thanks to Buchanan automotive for the advise. So we installed the new radiator and added some 8 litres of transmission fluid (which took about 1.5 hours!!) and went for a drive. Touch wood, the transmission seemed ok. I wonder if this is just a short term victory and it will fall off next drive?Either way at this stage I am happy with a short term victory, so off to get the brakes sorted, 2 new rear tyres and hopefully some classic car rego will be next!Cheers,Greg K.

ANF Posted 15August, 2016 Report Share Posted 15August, 2016 Sounds like a win! Did you go for the PWR rad? Link to comment Share on other sites More sharing options...
Gregk Posted 16August, 2016 Author Report Share Posted 16August, 2016 No I didn't get a pwr radiator ANF. Their best and cheapest option was the radiator on its own and a seperate transmission oil cooler, but I would have had to make brackets to fit it and change the length of the oil lines etc which I couldn't be bothered doing atm. Just wanted to get it running. But their stand alone transmission oil cooler is pretty cheap @? $120, so I will get one eventually when everything else is sorted. Cheers Greg.

ANF Posted 16August, 2016 Report Share Posted 16August, 2016 I have a PWR oil cooler waiting to be fitted, but like you want to get it running again and will then fit it.The fitting that Porsche used on both the engine oil and trans fluid do not make it easy however...... finding something for these fittings is nigh on impossible (well down here anyway).....Cheers Link to comment Share on other sites More sharing options...
Gregk Posted 17August, 2016 Author Report Share Posted 17August, 2016 Yeah right. I haven't even started to look at the options of fitting the stand alone oil cooler. I was hoping it was going to be a relatively easy task! Oh well, makes me feel better that I've just got it running. Soooo many other problems to fix first!!

ANF Posted 17August, 2016 Report Share Posted 17August, 2016 The trans cooler ones are ok to find as long as you go to the right place... the engine oil ones are an odd size that no-one stocks or can even get.The engine oil cooler is not needed as I have been told so I have just looped mine, and this is what has taken me the most time.....

Gregk Posted 3October, 2016 Author Report Share Posted 3October, 2016 Ok. Moving forward to the fuel distributor. It is the original CIS type I believe. We've bought a re -seal kit. Do people use gasket sealant for the stainless gasket? And if so, what type and where is it available in Australia?Cheers,Greg Link to comment Share on other sites More sharing options...
ANF Posted 3October, 2016 Report Share Posted 3October, 2016 You have made some progress/ had some success with the trans?Not sure on the sealant, but hopefully someone chimes in soon Link to comment Share on other sites More sharing options...
tazzieman Posted 3October, 2016 Report Share Posted 3October, 2016 I would call the Buchanans. You don't want to stuff up a FD reseal , by all accounts it's a fiddly business. Isn't shellac the sealant of choice? Any sealant that gets in the passages and orifices will be a disaster.See http://www.porsche928forums.com/download/manuals/CISRebuild.pdf Link to comment Share on other sites More sharing options...
