just had my trans rebuilt and he said the old housing had counter weights is what he called them on the tail. he said the one he took off my car didnt have them so he wasnt able to put them back on but he said they are supposed to be there and that i should look into getting it fixed. i was wondering if someone could help me with this. on where i could get them maybe from a dealer or something or if they HAVE to be on there ????
