You'll need a Nonlockup valve kit to correct the flow if you plan to use a Nonlockup converter. If you don't want the TCC to lockup just unplug the connector plug on Pass. side of Trans & leave the Solenoid in place. Not locking the TCC in 4th will cause Trans overheating. TransGo etc.. have them. Should find Info you need to know here>> http://www.turbobuick.com/forums/search.php?searchid=1790557
