The car manual says to change transmission fluid every 50,000 milesTransmission is working again for now, changed the filter, added a bottle of Lucas transmission fix and the same amount of ATF that came out when I took out the old filter(minus a quart to replace with Lucas transmission fix), ...cleaned everything up before putting things back together.Watched a few videos about it, ... I did not do a flush, just a change of filters and only added what came out, it was about 6 quarts. There are a lot of videos with the grim message, "don't expect changing your fluid to fix your transmission" ... in my situation it's going good,  for now.

Filter and Gasket looked identical to the OEM AC Delco parts I replaced.  The metal insert had some rubber that looked like it was pealing off, that's why I gave the review 4 stars out of 5 as I had to rub my fingers around it to take off loose rubber.  Wasn't too happy about that because any contaminants in the transmission may cause it to fail.  However I was able to clean it off enough to make me think at least it should be good.Trans took 6.7 quarts of fully synthetic Dexron VI transmission fluid after the pan drop.  8mm bolts were removed and then torqued to 124 inch pounds using a quality torque wrench (note I've known people to crack bolts with cheap ones like the ones from harbor freight).  The Fill bolt is 11mm on the passanger side and the engine needs to be running and level (can use magnetic level and attach to pan) when removed... after filling enough fluid should leak out of the fill bolt.  When done don't turn off the engine as you may lose 2 quarts... tighten the bolt while engine is running to 124 inch pounds using Loctite 242.  Note 124 inch pounds is manufacturer specs for what it was built with... service specs is lower about 89 inch pounds.  However, 124 seemed to work fine for me.  Just don't break the bolts or have the car drop on your head and you're good.Finally realize the earlier 4T45 transmissions received a service bulletin 08-07-30-04-0B on May 6, 2009, look it up in Google.  It calls for the replacement of the old square magnet to be replaced with two GM Part # 29535617 magnets.  The bulletin corrects an issue where the old square magnet was under powered allowing the metal to adhere to the solenoid instead of the magnet in the transmission pan.  To fix this they ask you to discard the old square magnet with two round ones and show you where to position those round magnets.  If you're going to drop the pan it's worth the $16 to fix this for the two magnets as it could trash the transmission using the original square magnet.  If you don't have the 1 square magnet in your pan it's probably already been corrected or doesn't apply.
