What part number for the filter - Impala Chevrolet Cars & Trucks

you should have the detroit/gm engine as to filters for oem numbers call a dealer and ask if off shelf order by make -model and engine http://www.duramaxhub.com/65-diesel.html

I am unfamiliar with the brand so unable to comment on the application but the problem you have is common throughout the filter world and there are several reasons for it...

Factories around the world produce fairly limited types of filters and they buy from each other to make up a fairly comprehensive range to fill up their catalogues and some companies don't even bother to have their own brand and part number applied to them but simply put one manufacturer's filter in their own box.

Some oil filter suppliers don't make filters at all and simply buy in what they need and sometimes they buy from application and cross reference catalogues and sometimes they buy by dimensions - thread size, canister size, etc.
The trouble is, cross referencing doesn't happen in a straight line. Out of the multiple thousands made it isn't unusual to discover many different filters originally intended for different application that are physically similar enough to allow buyers to choose the most profitable option and when they discover a more profitable option or they have a supply problem they bring in a substitute and invent a new part number.
Take the part number of a filter from a catalogue and cross reference it in another catalogue and cross reference the resulting other part number in a different catalogue and then cross reference that in the original catalogue and it logically should produce the original part number - wrong! At least it is mostly wrong and some of those filters being offered as suitable fitments are poor substitutes fitted only by the gullible or the profit-hungry.

Unless fitting a dealer part ensure the replacement is identical to the one you are removing and don't forget to look inside for a valve. Most of this of course applies mostly to spin-on filters rather than the new fangled paper element type though even with those it pays to be careful due to reports of some being made of inferior material.
If two part numbers are offered a wise person takes both on sale or return for obvious reasons...

baldwin filter B7139 replaces carrier number 96-101-33k ( P-96-101-33K)
If you do have a Balwin supplier handy then that number will cross reference to other makes
It is not a special filter as can be seen by going google and typing in---oil filter part number 96-101-33k
there are lots of pages with replacement part numbers and what they fit

all parts manufacturers will have their own number, Carquest Napa Shucks Autohaus AZ will all have this part in several grades and they can each give you their number and the stock number, you can also get a k&n filter that can be reused for life as long as its maintained with the cleaning kit, it will also increase your horsepower and keep filters out of the dump

if the engine is a 2.4 litre the oil filter will be in front of the engine on the left side at the bottom the filter number will be a 3506 usally a fram number but pretty much the same number for several oil filter brands if it is a v6 here's a photo

The filter is inside the transmission and my parts site shows no external filter. Here are the two part numbers (it goes by transmission tag number) I show and pictures of the parts.
BECK/ARNLEY Part # 0440328
Internal Filter; Transmission Must Be Removed And Disassembled To Change Filter

ATP Part # B319 {#4632139010}
Trans. code F5A51

there were 2 engine used in this year, both use the same filter

ACDELCO Part # GF652

there are only three things that really matter on a filter.1 thread pattern.2 seat size this is where the o-ring is. 3 microns, this relates to how small of a particle it will filter out of the oil. try wix.com

TRY A PENZOIL NUMBER PZ-34. IT SHOULD FIT JUST FINE. IF YOU NEED OTHER POSSIBLE NUMBERS SUCH AS A PUROLATOR(L14670), PLEASE KEEP ME POSTED. THANKS FOR USING FIX-YA.

Parts houses have a filter chart for determining the filter number. I believe that a #16 fram filter is used on yours but different "cross-over" numbers from other companies will also fit. Your vehicle capacity is four quarts with filter.
