So I'm here to help a friend with a s14. The car is automatic. I know sucks swap is in progess. So we had some problems during the swap and we had to install the auto tranny back on. It worked perfectly fine before. I have the car lifted on jacks. When the car is in gear it will just rev. The wheels will turn just a little but it feels like something is holding it back. Yes I checked the obvious. Ebrake is off. Shifter linkage. And torque convertor was installed correctly. Can it be the amount of fluid? The dip stick already show full but I only added like 3-4quarts. I heard when it's fully dranied you need more than that? Any help will be appreciated
