Do check the manual and ask for the specific items only. If you go in and ask for a 100,000 mile service you can bet on top of everything else there will be an extra $600+ pad on the bill.

Ive flushed my trans several times and never had an issue with it. Cooling system on the other hand, I waited too long and the coolant broke down and coated the inside of my system with brown goo. I couldn't get rid of the heat. If towing you should follow the extreme duty criteria. I should have changed coolant at around 40K miles instead of 75K miles. Cost me a radiator, aux cooler, bypass valve. Can get pricey.

Transmission and 4WD transfer case were due at 90K. Make sure to use genuine GM fluids, no aftermarket. I would also flush the cooling system. A true "flush", none if this "run it through the machine and add some magic chemicals" for all of the above !

I do similar at 100K, nice starting over point. However trans likely would have also been done at 50K or less, brake fluid every 2 years, PS fluid likewise. Coolant, every 3 years or so.

GM specifies a specific rear axle lube for the eaton autolocker on the duramax. Commonly known as "grape juice" because that's what it smells like.

For the transmission I'd recomend using Transynd not DexVI. As long as your changing it, why not go for something far superior to DexVI.

Several mfg have Transynd TS-295 certified fluids.


Often the rear diff/transfer case/front diff don't have a change interval specified. doing it at 100K is IMHO a good idea.

And check the brakes, new shocks?

Fount this on the web.

Looks like it recommends between 97 and 105 K:

Rotate tires, if recommended for the vehicle, and
perform Required Services. Check engine oil level
and oil life percentage. Change engine oil and filter,
if needed.

At 150,000:
Drain, flush, and refill the engine cooling system (or
every 5 years, whichever occurs first).
Drain, flush, and fill hybrid low pressure cooling
system, if equipped (or every five years, whichever
comes first).
Inspect engine accessory drive belts for fraying,
excessive cracks or obvious damage (or every 10
years, whichever occurs first).
Change brake fluid (or every 10 years, whichever
comes first).

Flush??? Transmission may be due for fluid and filter change, but the power flushes seem more detrimental. Water pump and coolant may be worth changing and or flushing.
Depending on your truck, and what you have done recently you may want to have the injectors cleaned/serviced, bearings and brakes checked as well as the transfer cases.
After all that if yer wallet is still thick, go fill er up and drive.
Happy motorin

Other than the scheduled maintenance items, if it ain't broke, don't fix it.
