Need help identify 5-speed transmission and where to order parts
I inherited a chopper that seems to have a mix of S&S and Harley parts. The transmission has issues where it gets stuck and wont shift gears. Specifically, it refuses to go from 2nd to 3rd gear. I am not very knowledgeable when it comes to Harleys/choppers but my research led to believe the problem may be bent shift forks, shift drum, or something with the shifter pawl/inner shift linkage.
I pulled the transmission, and the shift forks and drum have visible wear and scoring marks. The springs on the shifter pawl/inner shift linkage also seems extremely weak. Honestly, I am not sure how strong the springs are supposed to be though.
I would like to order parts, but I am having a hard time simply identifying the transmission to order parts. There is only one string of numbers on the transmission case, but nothing comes up online. Also, I am not really sure where the smart people order and buy motorcycle parts. Is the Harley dealership the way to go or are there some alternatives online that people recommend?
Any advice is greatly appreciated. Thanks.

Looks like an aftermarket trap door, however, keep looking, there has to be a part number for the trans case somewhere.
How about a part number on the inside of the top trans cover? It will help narrow things down.
Looks like a 5 speed with electronic speedo pick up, so from 1995 or 1996 on.
What year is the bike title? Pics of the wear on the drum and forks? That 5 speed drum and shifter mechanism can be upgraded to the newer 5 speed drum and shifter mechanism, so if your going to replace those parts, then consider the upgrade.

Like Yankee Dog said its a mixture of stuff, thats an old style shift drum with an old style shift drum detent, I would up grade that, they didn't shift the best and hard to find neutral, Baker makes a nice one but expensive, the newer stock harley ones are nice and will work on your tranny up to 2006, also make sure your shift linkage is all good, shift arm on tranny is tight and shift paw is adjusted

The bike title is registered as a "2001 American Eagle".
If I am reading it correctly, the Engine code comes back as a "year 2000, 4 inch bore, 8 1/2 inch flywheel diameter" S&S engine. The majority of the bike seems to be S&S parts. It appears to have a BDL clutch basket.
I will include a picture of the bike as a whole if that helps at all. Thanks for the information. Between what you and mike said I think I can go in and get some parts. Hopefully my diagnostics are correct.
Edit: I may be using the wrong words. Shift drum --> shift cam? Same thing?

Well the forks don't look as bad as I remember. I am not entirely sure how much wear is tolerable on motorcycle shifting forks.
The shift drum/cam has some deep gouges; they just do not show up very well on camera.
Cleaned up the trans case a bit and I found a logo that looks like it says CCI and maybe the remnants of a part number tag.
I was pretty confident that a shift drum/cam kit and forks would fix my problem, but I am starting to second guess myself. I just don't know all that much about motorcycle transmissions. Assorted photos below.

Some gouging is more visible here
Logo? CCI I think?
This was on the bottom. I
Hard to see but there are fairly deep gouges in the channels.

I'm thinking Rev-Tech 58305 series (CCI/Revtech) transmission.

I don't know if harley trans parts can interchange with rev-tech trans parts.
Nice pic of the drum. I see machine marks in the tracks of the drum, but not any crazy wear. I see some wear on the shift forks but a little hard to tell from the pics. Nothing super crazy.
I would check for worn pillow block bearings that hold the drum, shifter pawl wear and proper adjustment, shifter foot pedal to trans linkage adjustment and or slop, trap door bearing play, and any binding of the shifter forks on the rod or too tight/bent shifter fork rod.
Just reaching for some simple things at this point, but pretty sure it's a rev-tech, so thats a start.
I like the look of the bike!
