Recently went over 100k miles

[mattjones]

My '08 Tahoe LT recently went over 100k on the odometer, does anyone have any tips or advice on prolonging its life?

Just to give some background on the truck I've done the following in the past year or two:
-Had the throttle body and A/C head unit replaced
-installed an Airaid modular intake tube (to go with existing K&N air filter)
-replaced battery with an Optima red top
-replaced solenoid vent valve

Also, I get the oil changed with synthetic at Jiffy Lube.

Do the driveline fluids like front/rear diffs,trans, t-case.....

Install a catch can and don't touch it.

Can you explain what that is?

Check your plugs and wires
Start changing your own oil

Start changing your own oil

And filter , Jiffy lube sucks.

Bumping this thread, let the truck get a few thousand more miles on it since the OP but now I'm actually taking care of everything. Did some more research and spent labor day weekend changing the spark plugs and wires. My K&N air filter is probably about due so I'm gonna check and replace if needed.

Next project is gonna be changing the transmission fluid--completely. Not just dropping the pan but actually pumping out and replacing all of the fluid. Doesn't make sense to me to replace like 5 quarts while leaving like 12 quarts of the old stuff in there. Anyone have a link to the write-up thread someone did on that? Actually changing the fluid seems simple enough but I'm not really looking forward to getting under there to drop the pan.

After that I'll change the fluid in the diffs and transfer case, that all looks simple enough.

Who doesn't change there filter every time they change there oil?

And yes, Jiffy Lube does suck.

Why replace your K&N? Its washable, good for a million miles.

Here's a couple of threads in regards to DIYer fluid flush.

Ha yeah, that's what I meant.

Also, stupid question: this will be my first time actually changing fluids myself. What do y'all do with the old fluid?

I can think of a number of things to do with the fluid. First thought is that places like auto zone have a recycling deal (not sure if they take ATF though?). Second thought is that it good for getting fire going, particularly those wet/green piles. I have used it in the past to flush out differentials in my atv. The ATF seems to do a good job at getting out dirty (really dirty with the atv) gear oil.
