I am inquiring for a friend and this is very little to go on but maybe somebody will have an idea? She said when entering a roundabout she went to downshift and the car locked up. She said she was able to poke something in the hole on the shifter and it ran okay for a mile or two but now it sounds like the transmission is coming apart. I realize this is very big but it's all I know at this point does anybody have any idea but they could Point me towards?
