The car has about 125K on it, I got it at 113K. I have not changed the transmission fluid or filter. I looked under the car without jacking it up and could not see any leakage. After a bottle of Lucas transmission stop leak and 2 quarts of transmission oil, it all but stopped whining and mostly stopped slipping in a drive around the block. I am thinking the next drive I take should be to the transmission repair shop. I do what I can, but I'm not an ace mechanic!
