I have a 72 GMC K15 350 3spd np205. My questions are, what is the tranny called? Is there more than one model? What maintenance is required if any? Does it require any fluid replacements? Is it fairly strong? Ive been beating this thing for about 8 years and its still going strong.. I have had some linkage issues, replaced a clutch, the usual. Ive been planning on swapping in a th350 but this has been so good to me thus far. Thanks for any input!!
