I am wondering which would be the best choice of filters to use on my 01 duramax, fuel, oil and tranny. And which website has the prices. Thanks for your help.

There is no "best" for all persons for all applications.

Your efforts should be put into better defining your use and maintenance plans, and then picking products that support and compliment those plans. There is no need for a super-duper extra-expensive filter if you're going to change it every 5k miles. OTOH, I would not run an el-cheapo filter for 25k miles. You must match your products with your expected use; it's like that in nearly all things in life.

There are many good choices out there including OEM, Baldwin, Donaldson, Wix, Purolator, Fram, Amsoil, etc. They are all "good enough" to more than well protect your equipment when used in "normal" circumstances. Many can perform well in extreme circumstances.

Under "normal" use (following the OLM), the filters are secondary to controlling wear as it is the oil additive package that protects a piece of equipment. Only during extended oil changes does filtration play a major role. That in mind, don't fret over minute details. Choose a quality brand name filter and be done with it. There are now tens of thousands of UOAs showing excellent wear protection from just using normal conventional oil and filters for OCIs up to 10k miles. Using a premium filter and synthetic oil gains you nothing in such durations.

I did not read the above, but will agree with the opening statement.
What I will tell you is that I use a Wix fuel and oil filter, for the trans only Allison.
If I cannot get a Wix, NAPA Gold is next in line.

What I would tell you to find the filter you want, go with the majority here. Also if you go to Wix's web page they have some info from Filter Manufacturers Council. Or www.filtercouncil.org
http://www.wixfilters.com/productinformation/index.html
In the bottom right of the page there is a several links. MSDS/Tech Bullitens/and TSB's
That will link you into FMC's web page.
Also the pic on Wix's web page shows a good filter design.
Metal end caps on the media itself, and inner metal ring, a coil spring in the bottom.
The type of material used for the bypass makes a difference in longeveity, case thickness determins the strenght, along with the top of the filter.

To add to all that, the micron rating will also tell you how much it is filtering. (I do not remeber off the top of my head at the moment) But their are two ratings, one should be the smallest possible particle the filter can catch, and the second is the smallest particle is normally catchs. Something like that.
Keep in mind, a 2 micron filter will catch well almost everything, but say a 10 micron may be better because it takes longer to plug up.
At any rate that is my rambling.

I use Allison filters for the tranny and Wix / Napa Gold everywhere else. I have little doubt that there are many other good brands out there. However, I stay away from Fram, since they seem to have shoddy manufacturing / QC (I have found several of the filters with grit and dirt on the business end of the filter).

Most name brand filters are good filters. We put together a package with some of the best availble for all years of Dmax. A Baldwin oil filter, Allison Spin-on and your choice of Racor or Wix fuel filter all in one package for 1 low price shipped in the US. Canada we need to add some shipping to your orders.

You can also upgrade the Baldwin oil filter to an Amsoil EA full synthetic oil filter for 6.65 more per filter. We carry Baldwin and Wix Air filters for all years to add on also.

Sticky on Micron ratings at the top of this Maint section. Its good reading as are many of the stickys.

Fram, like many products nowadays, is a "get what you pay for" product.

Fram's OCOD (orange can of death) "normal" filter filters OK, but not fantastic. It's the construction that leaves a lot to be desired. However, their top of the line stuff is actually made really well, and filters quite decently.

I like Wix because I get them bulk online from Fleetfilter (actually they are the Napa Gold equivilants). Their construction is very robust and filtration is good, for a very fair price. But that does NOT mean they are the "best" for anyone other than me. They fit my maintenance plan, price point, design and build needs, etc. There are many other good filters on the market. I just put a PureOne oil filter on my Dmax this past weekend because I got it as part of a promotional deal when I bought some oil; Pure One are excellent filters as well with a very good beta ratio. So are all the Mobil 1 filters, etc. Amsoil makes simply awesome filters, but for my "normal" use, they are overkill and not worth the extra money from my perspective. Amsoil EaO's are fantastic for extended OCIs past 15k miles; very cost effective when you push them out to really long OCIs.

I simply have the dealer do those changes and install OEM filters. Saves me running around getting stuff together, crawling under the thing and then have gallons of old oil to haul (or worse yet spill) and dispose of. Best thing, as I've stated before, it may cost a few bucks more but it's helping keep some guy on the payroll.

I use OEM fuel and air but stick will the Allison for the spin on. I did buy a WIX fuel for a spare to carrry with me.

Don't forget the FUMOTO valve to help with changing oil in the future. (Got this valve and WIX filter from Dirtbikindad393) :)

Use K&N oil filters #3003 for Duramax these have the nondrain back valve in them. Allison spin ons for tranny, fuel filter new design at duramaxstore.com I forgot exact name but great price here what service too.

Each to his own, but I don't trust other people working on my truck. I have seen far too much lousy work and abuse of vehicles in the hands of mechanics. They gernally get paid by the job, not by the hour, and many slam out the work as fast as they can with little or no concern for your vehicle. I don't mean to slam all mechanics, since there are a few good ones out there, but in my experince, the butchers far outnumber the good ones. Did the lube guy inadvertantly put 5w-30 in the engine, did he clean and put back the magnet on the Allison spin on etc. These are examples of things that will come back to haunt you a long ways down the road.

By doing my own maintence, it forces me to look over the truck and keep an eye out for issues before they become a big problem. No one will spend the time to do as good a job on maintaing my truck as I will.

Just my $0.02.

Perhaps so however I know the guys doing the work. That helps I'm sure.

What I always tell people, if you know a good trustworthy mechanic, treat them well and hang on to them like gold!

Glad to hear you have someone you can count on.

I do my own changes, but you can't go wrong with OEM filters.
