Dexron 3 is the way to go (ATF). I used it for 3 years without an issue and it always provided silky smooth changes. I should mention dont use any additives as they are good in the short term but after 20,000 k's they cause probs in your bearings .
not sure if i have the same box but it is a w series box witch i have had for several years,when i run w80/90 i had trouble getting second when it was cold so i dicided to try the w75/90 from an ourtown oils newcastle as it was a lot cheeper then penrite.since changing to this grade of oil i have never looked back and fully recomend it in both t50 boxes and w series boxes as second is obtainable no mater wether its cold or not all gear changes are smooth with no wines or howles over the past 5years or so,also the 2 boxes have no noticeable metal flakes or signs of bad wear in any of the oil changes i have done this w series boxs was behind a 140 bhp holden 6 that coped a beating and the t50 was behind a 2tg that travelled 120 km daily for 2.5 years and also coped a beating. so again i recomend the w75/90 to anybody, but in the end its your joice ps w75/90 is not atf w70/90 is. the w75/90 is a slightly heaver grade or thats what im told. also dont mix w80/90 with w70/90 as this willnot work as it causes a cemical imbalance and will altimatle destroy your box or lsd diff
