Well I was doing some more maintenance to my Tb today. Had done the thermostat yesterday and remembered that the transfer case was approaching that 80,000km since last service. Last time I had used AT2 fluid from the dealer. I think that was in and around 2012/13 and the fluid came to about 16$ for 2 liters. It was not expensive by any stretch. I had the Tb on ramps and pulled the fill plug first, which came easy as I used some Teflon tape on it. Well it drained out more than expected due to the slope. The old fluid was dark but still blue in the light. In went about 2 liters of some left over ATF I had, Co-op ATF SL, which I had used in my old 1500 as it is a multi fluid and suitable for ATF+4. Its Canadian made group 4 and approx. 9$ tax in a liter. I had read much about the AT2 mystery fluid and saw that AMsoil multi ATF is now suitable for use. Well that is just a good quality full synthetic ATF, 7cSt fluid. Well what the [censored], lets try it. Did a decent run in and around the area to get the fluid warmed up and circulated and then put it in auto 4wd and did some runs on the grid road to see how the clutch lockup went. Just fine. No clunks, bangs, shuttering, nothing. It engaged great.
So who knows long term. Maybe it will blow up and I will curse myself for not using the mystery AT2 fluid.
