I performed three back to back drain and fills on the Aisin 8 speed in my Regal TourX. Only drains three quarts at a time, very frustrating; I'm going to have to find a more efficient method going forward but that's beside the point.
The first fluid swap I had some Idemitsu TLS-LV I used. I don't know why, but I have a weird habit of smelling transmission fluid before I put it in. Idemitsu smelled like a "light sweet" smell, nothing unusual. The second and third fluid change, I used Maxlife ATF. I had a couple jugs I bought a while back, and a friend gifted me a couple unopened jugs he no longer had a use for. Packaging is identical, all have Toyota WS on the label, so didn't think anything of it. First gallon jug I went through smelled very similar to the Idemitsu and other ATFs I've used.
I was filling from the 1 gallon Maxlife containers into a single qt. bottle for the transmission fills, so that I could get close to what was taken out, before I did the official fluid check procedure. When I got to the second jug of Maxlife (only needed about 3/4qt from it), pouring it into that single qt. bottle, an aroma of sulphur hit me like a freight train. Not gear oil strong, but it was unmistakable. I compared smell between the first Maxlife bottle and the second, and they are so wildly different that I thought I must have some used / counterfeit oil on my hands that my friend had given to me, I don't know where he got it.
I studied the packaging, seals, etc and nothing seems amiss, they were both virgin unopened bottles. I noticed the date code is different, so the only thing I can conclude is these are two completely different formulations. FWIW the one with the label starting in E1420 has the "dark" sulphur smell to it. Any insight on this?
