id change those plugs ASAP, thats just stupid to run original plugs that long imo. To me plugs are just another preventative maintenance item. As for the trans fluid, you might as well ignore and wait for it to blow if its been holding together that long.

LOL! Yeah, I'm gonna change them the first of the year. The old trans fluid might be what's holding it together. I plan on doing a 6.0 80e swap next year, so I'll just ride it out.

Mines pretty young at 103,000, but has some pressure put to her from time to time. I've owned it since 45k. At 70k the fun started with a turbo install. This weekend's gopro showed 18-19psi and 21psi on shifts with a 76mm.
I've broke the stock driveshaft and replaced 1 tie rod and a couple hoses that was mostly my fault for melting.
*** edit, should have said I got a 4.8, I fail!

Damn some of these mileages are crazy! I have 288k on my o7 classic, so I don't feel too bad. 4k ago I changed the original sparkplugs out, did a trans drain and refill (original fluid & trans), and diff service. I still need to do another trans service, and find out why I have a steering shimmy.
