I have a 16 silverado 1500 5.3 6l80 that started to shutter so I replaced the torque converter. After doing this I replaced the fluid with ac delco dex 6 and ensured the fluid was at the right level. I drove the care for 5-8 miles to test it, the next day I pulled out of my driveway and the vehicle was bucking and not engaging the transmission as if it did not have fluid. I checked the dip stick and it was at the correct level, I then dropped the pan and noticed the a lot of black sediment at the bottom of the pan(no shavings or big metal chips). The filter appeared to be clogged, so i changed the fluid and filter and then was able to drive around 40 miles before this happened again. Does this sound like a i need to rinse and repeat this process until the sediment that was jostled free during the converter swap is gone or is my transmission done for?
