1986 Nissan 720, 2wd shortbed, 5 speed. Door plate says FS5W71B, but I am only finding rebuild kits for the 71C. Transmission is leaking from rear output shaft, grinds into 2nd gear, and will pop out of gear when I let off the gas. 5th gear also has a strange rattle, but doesn't grind into gear. Also occasionally if I let it sit and warm up the engine will stall out when I let out the clutch, but as soon as I put it back in it will idle fine. If I just start it up and go I do not encounter this problem. Also I can't shift into first gear unless I am completely stopped. Once stopped, shifts in just fine.
So what I need to know is will the rebuild kits offered online from companies like cobra transmission that advertise their kit as being a direct fit for my truck work even though they are listed as being for a 71C?
