Glacier has loaner valve bodies which he could send you with a depot, and on the condition that you use clean fluid. If it's really a valve body problem, then you have two choices. Either you could pay the difference, and buy the valve body from him, or you could send it back to him along with your valve body for him to inspect, and repair. Another option is to have Central Valve Bodies check, and possibly repair your valve body. EF members get a discount. I saw this book. I have it as well as the update manual, and the Ford 3 ring binder.
