I recently purchased my grandfathers 2004.5 Cummins 4dr long bed and have been doing the much needed maintenance after 242,000 miles. Needless to say it didn’t always get maintained and I just replaced the stock injectors and started to service the trans. That’s when I found about 4 inches of a snap ring in the pan. So now I’m weighing my options and I plan on putting it back together with a new filter and fluid as I need the truck for work. But I’m looking to swap in a manual instead of replacing the auto with another. I’m located in Oregon and willing to travel. Hoping someone on here might have the trans, interior ,shifter, hydraulics etc. I plan on using my tcase and getting rid of the garbage 2 piece driveline. Or just looking for advice on what route to take, I’m mechanically inclined and do have help when needed. Any input on sourcing parts would be much appreciated!
