Yeah, - yer probably right...
However, I am somewhat curious, - just how long will the engine go anyhow?
And what of the automatic tranny in this truck? - do they ever die, or just keep going and going too?
PS, - I did make the mistake of replacing the filter inside this tranny a couple of years ago - big mistake... (and waste of time).
I devised a scheme to hook 2 pieces thin/cheapo garden house to the ends of the flared fitting lines that attach to the oil cooler on the radiator to drain it. That worked well - draped the 2 hoses down into a 5-gal Homer bucket, started the truck, and it all pumped out nicely into the bucket. Wahoo. (used 2 hoses on both oil cooler lines because I didn't know which was pressure, and which was return).
Dropped the pan, wiped it all out (so where's all the dirt/sludge that I was expecting?) ....
Got the new filter (which was really huge, and quite elaborate), installed it, and put the new gasket on, fitted the pan back on, and started loading it back up with juice. Trying to get a stable line on the dip stick, and scratching my head, - what's going on here.
I decided to peek underneath, and HOLE LEE F*** - total pink/red water fall around the sides of the oil pan.
Long story short, - F-ing Shucks sold me the WRONG gasket, and they were now closed at this point (Sunday evening), and I need to go to work in the morning. Sumbeech.
The new (wrong gasket) had some sort of steel circular standoff spacers around the holes inside the gasket. Well, the oil pan on this truck also has some raised sheet metal spacer deals pressed (swedged?) into it around each of the holes. The end result was that there was a gap between the pan and tranny that I guess I didn't catch.
Anyways, was able to salvage the old gasket which was perfect (and back on the truck, and dry as a bone to this day).
After all of that, the real kicker was this. After I cleaned up, I picked up the old filter which I left sitting on a cardboard box to wick out all of the tranny fluid. I put it up on the bench, and carefully cut it apart to see how it was constructed, and to see how much gunk/shavings might be in it.
I was shocked. Nothing, nana, zip... There wasn't anything INside the filter element, or the OUTside of the filter. Besides, the thing is big enough, and arranged like a vacuum cleaner bag which was is enough to hold all of the junk is every automatic tranny that I ever owned in my entire life, and I turn 49 next Sunday!
So all that work for nothing. Well not really I guess, - I did learn something. I learned just how well built the tranny is in this truck, and that I'll never do that again, and tell everyone with a truck like mine that it's not worth the bother to drop the pan and change the filter. Just get one of those quickie lube places to do a fluid exchange on the tranny fluid at least one in the life if the vehicle (like I did a few years before I attempted this).
