Yup. Sticker right on the side of the thing says so.

I run GM Synchromesh. Much nicer fluid and makes shifting smoother.

My owners manual says that the T56 doesnt require ever changing, but I will feel a whole lot better changing it every now and then. Do you guys change yours and if so how often. Ive heard around every 15K-20K.

I don't think you'd need to change it that often. I changed mine when I bought my car (12k miles) and I had to change it again when I put a new clutch in (18K miles). I'd say probably every 50K, if that.

If you're one to miss shifts and grind gears, you might want to change it more often.

I just had my tranny rebuilt due to worn blocker rings (2000 had the old paper type), and the tranny fluid and tranny were still immaculately clean. This was at 60,000-65,000 miles and the fluid had never been changed. That said, I would agree with the 50,000 mile change.

what about royal purple? the previous owner put that stuff in there... to be more specific it is royal purple syncromesh tranny fluid... it was put in there when the transmission was rebuilt last year.

Tranny fluid doesn't get much better than RP.
