Manarius Posted February 22, 2007 Share Posted February 22, 2007 I highly HIGHLY doubt that any car back in the early 90's came with synthetic anything with regard to fluid. Quote Link to comment Share on other sites More sharing options...
nipper Posted February 22, 2007 Share Posted February 22, 2007 JUst good old fashioned red blooded tranny fluid. I can look in the morning to see what my owners manual say, but its mineral based nipper Quote Link to comment Share on other sites More sharing options...
Snowman Posted February 22, 2007 Share Posted February 22, 2007 I'm pretty sure they didn't even have Dexron III back then:rolleyes: . I seem to remember the dipstick on one of my old loyales saying Dexron II. Same as with my 1987 Yamaha outboard. I found a couple cases of TCW-II 2-stroke oil sitting out back at work, and I wasn't sure I should run it in my engine, but then I remembered that that's what they had back then.

Petersubaru Posted February 22, 2007 Share Posted February 22, 2007 I have heard that soon, (if it isn't here already), will be the dexron IV ..supposedly better cold flowing properties...

ericem Posted February 22, 2007 Author Share Posted February 22, 2007 Does dextron IV work in my particular year vehicle? But i thought synthetic fluid came out A LONG time ago, just a little expensive. And Dextron III must have been available at the time, because subaru recommended it.

porcupine73 Posted February 23, 2007 Share Posted February 23, 2007 Synthetic engine oils were available back in the 70's. Not sure when syn atf's became available. There was some endwrench article saying subaru doesn't recommend synthetic oils. It doesn't say the recommend not using them though. Some of the manuf's pushes toward better 'cold flow' and thinner fluids are for better mileage/cafe reasons. Quote Link to comment Share on other sites More sharing options...
svxpert Posted February 23, 2007 Share Posted February 23, 2007 the first yr is 2007 in Canada.. the States??? the 5EAT uses synthetic ATF Quote Link to comment Share on other sites More sharing options...
ericem Posted February 23, 2007 Author Share Posted February 23, 2007 This is why i ask, becasue i heard the new gen subaru's use sythetic. So why not use the same stuff in my tranny Quote Link to comment Share on other sites More sharing options...
porcupine73 Posted February 23, 2007 Share Posted February 23, 2007 The 5eat's may run synthetic (idemistu), not sure if it's full synthetic or just partial synthetic, probably similar to nissan-j. But it is not the same as dexron iii, synthetic or dino. Different dynamic frictional characteristics no doubt. Quote Link to comment Share on other sites More sharing options...
Richard1296 Posted February 23, 2007 Share Posted February 23, 2007 My 90 Legacy's owners manual calls for Dexron II. Dexron II is no longer available and has been replaced by Dexron III and Mercon/Dexron compatible types. I use plain old Mercon/Dexron in my 90 Legacy and the 2000 OBS. If ever I was to repair or replace either transmission I would use a synthetic though. And I'd add a small transmission cooler to supplement the factory cooling.

Manarius Posted February 23, 2007 Share Posted February 23, 2007 This is why i ask, becasue i heard the new gen subaru's use sythetic. So why not use the same stuff in my tranny Your transmission was designed with dino oils in mind..not synthetics? Quote Link to comment Share on other sites More sharing options...
nipper Posted February 23, 2007 Share Posted February 23, 2007 Use a blend to be on the safe side. Not all trannies like synthetics. Transmissions need friction to operate. After many many many many miles of dino, i would stick with dino. Nothing may happen, but why chance it. Also i dont thinkthe costs warrent it. nipper BTw the car came with pinkish fluid when new, if that helps :-p Quote Link to comment Share on other sites More sharing options...
ericem Posted February 23, 2007 Author Share Posted February 23, 2007 Transmission had a full rebuild and all seals were replaced, and it has been tested not a SINGLE leak at all. Im dumping in my normal ATF screw it $10 is cheaper then $40 for synthetic. Quote Link to comment Share on other sites More sharing options...
