Did a drain and refill at 50,000 miles, life indicator showed 73% remaining but I had a lot of tcc shudder around 50-55 mph which is a big part of my driving time on rural roads.
Got almost 4 quarts to drain out (sat about one hour). Manual shows 8 quarts capacity so you get about half of it this way.
Drain oil looked more like moderately used engine oil, not terribly dark but not much of the typical red dye color of Dexron.
You can pump 3 quarts in without the engine running but need to fire it up to get that last one in - of course the fill port is adjacent to the left exhaust pipe, LOL.
This configuration is done so the trans can be filled, tested, and sealed at the powertrain plant. They have drybreak fittings and the assembly plant doesn't have to do any oil fill or checking which is always a big headache on the vehicle assy line. This was first done at GM with the 4T40 on the Cavalier back in 95.
Personally I'd much rather have a diptstick and fill tube. Not sure if any other mfgrs have gone this route or not?
