How to Change Trans Fluid in a Manual CTS-V's TR6060

[@isnowyazn]

For anyone looking for a cheaper Alternative, Mobil Delvac 1 and Castrol Transynd 668, are both really good high mileage options, which supposedly don’t shear down that much, while giving a good viscosity for all kinds of driving. I do think that the older Castrol Transynd for 295 and 468 (Dexron III/Mercon V spec), probably worked a bit better, since they’re thicker overall, compared to the newer 668 formula… I mean, I’ve grinded 2nd and 3rd once in a while when my trans temps climb past 200+ F, but it could honestly just be my stock TR-6060’s synchronizers… I plan on eventually getting a hybrid carbon fiber synchronizer (OEM) upgrade, as well as better shift fork pads and bushings, since all of the stock gearbox parts seem to be problematic for harder driving… How sad.

Would there be a way to snake a funnel attached to a long plastic tube down to the fill plug somehow? That way it could just gravity drain and I could fill it from up top?
