So I got this 02 s10 crew cab with a 4L60E auto in it rn but I want to manual swap it cause from the research i've done gm never made the crew cab manual and i'd love to have one of the only manual crew cabs. I guess what i'm really asking for help with is, am i only allowed to use the nv3500? like is that the only one that would bolt up with the 4.3 or is there any other transmissions that would bolt together?
