TEST # 7 (Regular Method)

GROUND THE D WIRE AT THE TRANSMISSION

^ Shave a little insulation from or pierce the D wire near the transmission connector. Reseal with silicon.




^ Connect one end of a jumper wire to the bare wire you just shaved or pierced.

^ Connect the other end of the jumper wire to ground.

^ Road test for lock-up (can be done on lift).

^ If you're not sure if lock-up occurred, then hold a steady speed of 60 mph (on the lift) and lightly touch and release the brake. You should feel lock-up disengage and re-engage.
