Upon reading the above post and seeing that someone has never used a pressure gauge on the trans I've come to the realization that I've been misled by the FSM and the Carl Monroe book among others...... gauges are for incompetents, a waste of time, are of no use and just for shade tree hacks who have no clue. What was I thinking. Much better ways to diagnose I now see. Good luck:thumbsup:. :rolleyes:
