My advice. Sell the car because that transmission fluid running in your engine is tearing it up. Your bearings are probably about to give up. If you don't want to sell it I recommend either rebuilding or buying a whole new engine and for sure replace the transmission
Thanks for the response,now it has aprox. 500 miles on it since i changed the oil and filter,will just run it and play it by ear.
