I just got done installing Hooker super comps on my BBC/TH350 setup (yes... I know, its a th350). This is an all-new setup and honestly I don't even know if the trans is any good. I installed a new shift cable and I cannot get park to engage. I do not have the backdrive linkage installed, and honestly I don't think it would fit around the massive super comps anyway. Can the car be driven without the backdrive linkage? Is this why I cannot get park? Or am I missing something in the shifter cable adjustment? Any help would be appreciated!
