Use a can 1 gallon of WD40 to flush it don’t start it just pour it in and let it sit. I just cleaned out a stick transmission this way last week . I tried everything castrol super clean, lestoil , a bunch of degreasers . Stuff was still caked up in there it had sat for 30 years.
I had that black sludge on my hands was into my skin . Sprayed some wd 40 on it like I had a 1000 times to clean my hands and bam it ran right off . So I sprayed it in the trans and it immediately loosened up everything
I was amazed at how good it worked inside the trans. . I mean nothing else was even touching it. I’d say diesel woukd do the same but idk this wd cut through this stuff so fast I think I’d go with that .
