I have a 2001 2500HD 6.0.

 

I want to change the tranny fluid and filter. How much fluid does it hold?

I've changed fluid in a manual tranny, just refilled it to the top of the fill hole. Is it the same on an auto trans?

I bought a filter from the chevy dealer. He said there was a gasket too that was available for $60 !! Is this gasket necessary?

 

 

any how-to's on here on exactly how to change the tranny and filter?

 

thanks all !!

There is a filter from what I heard in the transmission, os in order to change it, you have to drop the pan, which then you would put a new gasket on after wards. I think it takes 11-12 quarts of tranny fluid, I had mine done via a flush from the machine.

I just changed mine ATF yesterday....

 

I bought a WIX filter from Oreilly for about $20, I think

 

Used Pennzoil Mercon VI, and it took 5 1/2 quarts....I have a 2wd, so I don't know if that is different from the 4x4

 

It was pretty easy, as far as transmissions go...nothing in the way, and the pan just dropped right down. Filter just pulls down from the valve body...

 

While I had the pan off, I installed a drain plug for about $4 from Oreilly....I generally change the fluid in the pan about 20K miles and the filter every other time....

 

The gasket on mine is reuseable, as long as it is in good condition....just wipe it down and put it back in...no runs, no drips, no errors!!

 

 

Gonna do the rear end tomorrow with 75/90 synthetic....bought 4 quarts...hope that is enough...ha

The rear end used just a tad under 3 full quarts....I used Castrol Syntec 75w90 synthetic. Was super nice with the drain plug...

 

Then I changed the antifreeze...what a dammm mess with no petcock....oh well....GM saved $.30!!!

      This is a really late reply but I just found this thread. They won't sell the hinges. I've gone 7 rounds with them. Their solution is to buy a new cover. I'm about to buy a new cover and it won't be a Bakflip. It also won't be from realtruck.com.

      2 speed transfer case optional now?

      By Chuck FB · Posted

      Yes, and also pulling heavy trailers or a large camper up steep grades as well as descending grades such as the more rustic off road camping locations and using engine braking with that low gearing as well as soft ground can just suck the power . I realize pickups these days tend to have an over all lower first gear ratio compared to automatic transmission pickups from years back so that has helped a lot in its ability in high range but there comes a point if in four wheel drive the torque runs out at the wheels, certainly with a gas engine. They don't put two speed transfer cases on pickups for a cool factor, they have a function if one needs that massive torque to the wheels that high range can't deliver.

      Notes 7/18/2026   3,400 miles on this batch of Mobil 1 Euro 5W40 since the GDI pump replacement. Alcohol runs very clean when ring seal is tight and the sump isn't getting hosed with fuel. Checked oil level at fill up today as is my practice and grabbed a white Kleenex to look at the color. What color?  I was going to change it but.....

      Gas Prices

      By Chuck FB · Posted

      Interesting, I suspect I would have fueled up in Lee Vining as the day prior I would have filled up either in Laughlin or near there and maybe again before I entered Death Valley and once out the other side late that evening as I kept on driving into the night up near Lee Vining. Next morning I most likely fueled up in LV before heading over Tioga Pass into ( as I refer to it as "Yose .... Mite" 😁 ). And again that was 19 years ago but the price then must not have jumped out at me like the 5 bill a gallon theme of nutty cult hippy country Big Sir or head so far up their rear Aspen. I'd be curious to know where the highest prices are in the lower 48, I probably would not be far off to guess somewhere in Cali forn ie. Coldfoot and Prudhoe bay may have those prices beat but that is a whole other world up there and when prices are more normal elsewhere that is about what they can be up there I believe in no mans land. Anyway interesting that the 395 corridor is hosing people and the thing is, its tourist season and its not like there are a lot of competition options when driving up that highway from what I could see. Yup, big ole Boaterhomes and various other RV's ahead and behind me at the Yosemite entrance gate and they have to get their fuel somewhere.
