Its not a full transmission repair. Its just the valve body, which is a part in the transmission. This is a common part in all automatics, so I'm guessing the average Nissan tech shouldn't have a problem performing this procedure. 2000-2001 Maximas had a similar valve body TSB as well which firmed up the shifts.ekaxel said:Before you get all excited, that is one TSB that replaces an external part without even removing the transmission. I don't see any hint of disassembly or internal repair.
