Actually an typo in the bulletin. Errors seem to be common, even when correcting other errors. This TSB replaced a prior incorrect one
There is another TSB about flushing the transmission cooler and piping (not the transmission), and the flushing machine uses T-IV (no detergent) and GM says it's ok for the vibe, but that little to none of the T-IV remains in the lines after and what little does, doesn't create a problem.
I haven't yet been able to find the total fill capacity of the Transmission system. Was wondering as I'm going to do a full replacement by opening up the transmission cooler return line, after dropping the pan and replacing the oil in there and continually filling it as it flushes. The stuff aint cheap so I'd prefer to have an idea.
The last car I did the same procedure on used about 2 1/2 times what was in the pan, before the fluid starting coming out fresh.
