My 525iT's slushbox was allegedly rebuilt "recently" as of a couple of years ago. I hate automatics, but this one works fine and I don't have the resources for even a stock 5-speed manual swap, let alone the 6-speed it deserves, so it's best to take care of it in the meantime. Were it original, I'd go "f--k not with", but I figure it hasn't been too long since its last change, so I bought two gaskets and a filter... now what about ATF? Any recommendations? All I've ever needed ATF for was steering fluid, and just went with whatever was cheap, but this is a fussier machine.
Is that the GM A4S270/310R ?
Black label on the pan or green label?

GM trans? Dexron
Don't forget to drop and clean the front O/D section oil pan. The gasket for it needs to be ordered separately, doesn't come with "kits"

ditto, Dexron. Spring for the extra bucks and get full synthetic i.e. Amsoil, Mobil 1, Redline, etc.

I hadn't actually looked at the label, but assumed it's Dexron. I was asking for a product recommendation. Yes, I separately ordered the front gasket.
Is the likelihood of transmission seal leaks from switching to synthetic comparable to that with engines? I'd like to give it high-quality oil but damned if I have to replace the input seal shortly after.
Well, might just have to roll the dice on that one. I believe all current flavors of Dexron which are backwards compatible with the Dexron III, which was the original spec for your trans, will be at least a synthetic blend if not full synthetic. Depending on brand, some Dexron III's back in the day could be synthetic/synthetic blend. If the input seal is an occasional drip, then so be it. On the down side, a pronounced leaky front seal could be a bigger problem as in the 535i/735i ZF 4hp22, which usually leaks because the torque converter journal bearing walks forward and pushes the seal out. Let's hope you don't have to deal with such a scenario in the dead of winter. On the upside, it's an easy fix once the trans is out.
