Brought in in pieces, couldn't test drive. Battery dead. Rat turds under the hood
P0719 TCC/Brake switch "B" circuit signal low/short
Problem
Shifts good, computer will not send signal for lock-up. Brake switch always "closed" on scanner, even with switch disconnected. Truck runs very cold, about 165F. What temp. does the computer need to see to enable lock-up? Thank You.
