Fireman31 Posted November 15, 2008 Report Share Posted November 15, 2008 or blow it out with a compressor You can do that but you have to be extremely careful, using to high a pressure can damage your radiator/aux cooler....in fact most trans builders/shops will recommend against this method.....the aerosol is inexpensive and works very well.
