I have a 2007 Chrystler 300c 5.7 hemi nag1 5 speed automatic, The other day I was driving around town and I noticed as the car down shifted from 3rd to 1st it had a noticeable shutter, (only down shifting though when acceleration there is no slip, whine, or jolts ) I checked the trans fluid and it was reading 110 mm, when it is supposed to be reading around 75 mm. I drained all the fluid from the pan and replaced the gaskets and bolts and put the correct amount of fluid in the car. I drove it around the block and it drove perfect. I let it sit for a few hours went to run some errands and the shutter is back. I have no idea what it could be at this point I need help! If you know anything please comment

Could be a bad dipstick tube o-ring letting water in. Pretty common problem on early NAG1s.

Curious, how does one test one's motor mounts?
Pop the hood make sure you’re on pavement, put it in drive, and press the gas a little while holding the break if the engine jumps you need new mounts, it will have a little slack but it will be noticeable. you can also inspect them underneath your car, inspect the rubber boot and see if it’s cracked or in my case gone 😂
