Can Catalytic converter’s being removed Cause transmission issues

Hello, for some reason, your transmission is seeing that it's not safe to shift when accelerating. If you remove your catalytic converter, you can change exhaust back pressure dynamics and cause other concerns -- so whereas I can't say removing the part will influence this, I can say that it's always essential to get the vehicle back to a factory delivered condition and recheck operation before trying to go around that to troubleshoot. www.repairpal.com/repair-shops
