Happy Friday Gentlemen, I'm in the middle of replacing the tranny filter and fluid in my 1999 C2500 2WD Longbed w/ 10.5 HD rear, which hauls a sizable Lance Camper, ie, not a daily driver. It has a 152K and I bought it from the original owner (still in contact) and he doesn't remember if he ever changed the filter. The fluid looked old (dark red), but didn't smell burnt and there was no particles in it or in the bottom of the pan. The insides, from what I can tell looking at what I can see, look great. I have a few questions before I button it all up:
Filter Seal- I cannot seem to get the Filter Seal out despite using snap ring pliers; needle nose pliers; and (carefully) a screwdriver. I'm pretty ty sure I have to destroy it to get it out, and am worried about damaging the inside of the boss that's part of the transmission body if I try to pry. Like the pan gasket itself, which I am keeping, this seal seems to be in very good shape. I want to just leave it in there, like the pan gasket. What do you guys think?
Magnet: There's a magnet inside the pan on top of an indentation with squiggly lines (see pic). Is this from he factory? It looks like it belongs there, though I've never seen anything like it.
Pan Gasket: As per the service manual, I'm gonna leave the pan gasket in place, though I do have a new GM one. The filter and fluid are USA-made, but the new gasket is Mexico, though it seems very robust. In any event, the old one is in great shape. What do you guys think?
Drain Plug: Man, this short-shouldered bolt would not come out with hand tools and was a real PITA, esp. lying on my back. I took the pan off and removed it with my impact driver. I did a number on it with the hand tools on my first try, though it still looks serviceable (see pic). What is the minimum I can torque it down when I reinstall it? I do have a higher-shouldered magnetic replacement on its way, and will likely use that one if it's not Chinese crap.
Pan Finish: The finish on the outside of the pan is in such great condition, I almost thought it was aluminum! Man, what finish did GM put on these things??? It's been sitting under the truck in Oregon for 25 years and has 152,000 miles of rain, dirt, rocks, etc. I'm super impressed and would love to finish other parts under there in same as I go along. Of course, if it's some kind of powder coat (which wouldn't last that long anyway) that's probably out of the question. I'm just super curious if anyone knows specifically.
Thank you all in advance. This site is really awesome! P
