[Diy_efi] tcc lockup help needed

[Bruce]

Unless the TCC is specifically designed to be operated in that mode, you're
asking for trouble.   The oem tcc linings tend to be rather soft so it
doesn't chatter when being applied.  This softness, translates to shredding
of the lining, and filling the tranny with said shreds (when slightly
abused).  Not a good idea.
   In general the TCC is just meant to eliminate the slippage of the
converter when in cruise mode, to help with mileage.
   If you dead set on running a full time TCC lock in high gear, then just
use the brake switch and 4th gear tranny switch in series with each other,
and ground the lead normally going to the ecm.  Thou, I wouldn't.
