Hi all. I am having an issue with my sons 1984 camaro transmission. The motor and trans combo came out of a running driving car but I have a B&M shifter in the car. My problem is that it will shift just fine when we put it into OD but if you manually shift it into Drive, 2nd or 1st it acts like it is in neutral.....anyone have an idea what could be the problem. It has sit for a couple years, fluid level is ok and shifts normal in OD. Any help is greatly appreciated.
