well i guess it was coming but at the 320,334 mile mar my 02 duramax finally had something break ( besides having to replace the injectors 4 times nowwhich is not cheap). but i went to drive it to work and it wouldnt start then i put the charger on it and it fired up for a couple minutes, went to put it in reverse and it goes no where. feels like it doesnt engage into reverse at all. i cant be mad though i would say i got my moneys worth.
Time for a new truck? Sounds like your giving up on it... Lol

what cab configuration? It sounds worth fixing for a race truck built ally and a 7.1 stroker and twins. if you sold it cheap and in i would seriously consider buying yes thats quite a drive but if its THAT good of a deal lol. Also could be fixable, does the engine run fine? you can get built internals for the ally for about 2,000 uninstalled
It could be just something eletrical... That tranny looses reverse when the gear selector goes out

oh im not giving up on her, still a great truck. Now that they finally made a aftermarket injector for the first gen durmax i wont have to worry about the injectors going bad every 40,000 anymore. i havent even looked into the tranny problem yet, i dont have the time and i have so many projects going on. so until i get to it shell stay parked in the driveway.
Very doubtful it is an internal part on the Allison go bad. Check the NSBU (neutral safety back up switch) those can get corrosion and go bad, causing some issues. Congrats on getting it 320k though. The LB7's do have some injector issues. You should check and see if some LLY or LMM injectors woul work. Those have no issue with them.

The newer injectors use less voltage
so I dont think that would work.
