Ok my buddy is having a problem with his tranny. It drives and shifts fine with no slipping. Also when you first turn the car on its fine theres no vibrating or noises. But when you drive the car for a bit and put it back in park, it vibrates like crazy and sometimes it will make a screech or grinding noise, cant tell yet. But if it sits in D or neutral its fine, no vibrating or nothing.. anyone know what it is?
Thanks
