Ive recently picked up a 86' 300zx non-turbo trans (5speed) nd I have the 77' 280z bellhousing on it. but with the bellhousing on it will not shift into any gears except 5th (Possibly reverse if its a dogleg or whatever they call it). So what could be a problem? The shift rods clear the rod holes in the bellhousing and everything. but it wont shift. with the bellhousing off though, it shifts fairly well. any help would be great as I need this car running for going to work.
