100k Mile Scheduled Maintenance

[nickgreensco]

Hey guys, my 2009 Chevrolet Silverado 2500HD 6.0L Vortec hit 100k recently and instead of taking it to the dealer to have the maintenance done I was thinking about doing it myself. Y'all have some input on what NEEDS to be done and what doesn't. I've heard a few different things but I'm getting ready to go shopping and need to know what to put in the cart. Thanks in advance!!

Just the basics, new spark plugs, change out the transmission fluid, transfer case fluid, both differential fluids, I'm guess it is a 4x4? Change out the belts, that is if you have one for the engine and one for the AC compressor like I do on my 2002.

You can change out the spark plug wires if you want, I haven't and got 147k on mine. I will probably when I hit 200k.

Give it a good look over and see if the shocks are not leaking. If they are then replacement is due. Not much else, the usual engine oil change and air filter if it is time as well as the coolant since you are at 5 years.

Some suggest changing out the brake fluid. It couldn't hurt and isn't expensive. Power steering fluid as well. That is easy to do with a turkey baster.

That is pretty much it.

Nick got it covered.

Don't forget to grease all your serviceable joints and linkages.

Ok that's what I had in mind. However, I heard from a few people that I shouldn't change out my transmission fluid bc it will never run the same again.... How true is that? Or are there just certain precautions that I should take when doing it. I was told just to top it off. But I know it's recommended to flush it at 100k miles.

If you transmission fluid is still a reddish color you shouldn't have any issues. Drop the pan, change the filter and top back off. You can even pull the cooler line running from the transmission cooler in the grill and do a fluid swap that way. It will take 14 qts of fluid to get all the old out and replace it with new.

Now if you have really dark burnt fluid, well, then you are on borrowed time anyway. You can either just let it go and wait, or chance it with just changing out the filter and the four to five qts it will take to top it back off.
