I drained my A/T cold and replaced the exact amount that came out (4 quarts, 12 oz.) with Castrol Dexron VI and Lubegard Red at 24K. I now have 26K and have felt no negatives (or positives) since doing it. I'm happy to have replaced approx. half the OE fluid with fresh stuff. I plan on doing this every 25K which should insure a constant supply of fresh additives...I think this is a better plan than flushing....

I have a 2016 cruze limited and the frist time I drained the trans 5.8 quarts drained out. Frist I put 4 quarts back in shifted through all of the gears and got the trans up to temp and put a total of 4.2 quarts before fluid started dripping from the fill plug. Is this right? After this the trans seems to shift a bit harder. Should I put the rest of the 5.8 quarts i drained out?

Yes. Why would you not out back what drained out?

After reading all the post on cruzetalk alot of people said to fill the trans till fluid starts dripping out of the fill plug on the drivers side of the trans while the cars is running. That's what I did 3 times and always ended up pouring in 4.2 quarts. Why would GM over fill the trans by 1.6 quart at the factory?

It's highly unlikely they did. Of it had been overfilled by 1.6 quarts it would have been venting it out, or churning and aerating it causing shifting issues, vibrations, etc. I've never seen a factory filled unit over filled by more than even a few ounces, let alone almost 2 quarts. I'd highly recommend you get someway to assess you fluid temp and set the fluid level properly. Fluid is meant to be approx 194F(90C) when level is set.

No I hear what you are saying. I do have the scan tool to check the trans temp and everytime I got the trans up to temp and yes 90C I would pour in 4.2 quarts then fluid would start dripping out of the full plug. The three times I have drained the trans and made sure the trans was up to temp everytime I was only able to put in 4.2 quarts till oil started to drip out of the fill plug. Also I have read a post on this site from a amsoil person and he said that 5.6 quarts of fluid came out and refilled the trans at 4.2 quarts. I get that you should measure the amount of fluid that comes out and put the same amount back in but than what is the point of fill plug on the driver side of the trans because that would be wrong right?
