This is from my 20 year old 1997 GMC Sierra 1500 with the 4L60E transmission. It has about 85,000 miles total on it. I have flushed this transmission several times over the years but never did a pan drop and filter change till today. Just wondering if this looks normal? To me is looks clean but the magnet is loaded up with a thick layer of gray gunk. How did the "rows" pattern get on the magnet? Once cleaned off it is flat. The ATF has been in the transmission for 6 years and has 12,000 miles on it. I changed it because of age and sitting a lot.
Also included is the original transmission filter. I have never seen one of these and curious how it looks to trained eyes. Tried to get a close up of the filter media. The factory filter is metal on one side and plastic on the other. The only replacement NAPA had was all black plastic. Is this a good replacement filter? I hope so as I probably wont change it for another 20 years so it better filter, flow and hold up well....fingers crossed!
So what do you think:
Here she is still looking new after all these years! I love this truck!:
