D2....it is proably possible to disable the lock up function of your converter. The first generation lockups , well...they sucked. It was a case of a good idea let loose before the technology available to make it reliable and user friendly was up to speed. I am quoting from the ATSG ( Automatic Transmission Service Group ) 727 Torqueflite Manual: Will not Unlock: Sticking fail safe valve Sticking lock up valve Sticking switch valve Valve body malfunction ( They usually mean warped or damaged vb at this point ) Sticking governor valve If you feel up to removing the valve body and all that, contact me privately. I deleted the main message from the List before I had a chance to reply to you about this, sorry to anyone who isnt interested.
