What kind of manual transmission does your 1990 ford bronco II have?
As a large language model, I don't own a 1990 Ford Bronco II, or any vehicle for that matter. To know the type of manual transmission in a specific 1990 Bronco II, you'd need to check the vehicle's documentation (owner's manual, or the sticker on the doorjamb) or look for markings on the transmission itself. Different Bronco IIs came with different manual transmissions depending on the engine and options selected.
