Been reading the posts here and need some help. Have an 86 Cutlass with a 231. There are 16 bolts on the bottom of the transmission looks like trans # 5. There is no trans throttle cable on the side at all. Located one from Auto Zone but I doubt it's the correct one. Auto parts stores do not have the cable. Where do I locate the correct cable? I looked online but do not want to get the wrong one and deal with returns and time lag.
