TCC is commanded to lock
Unlatched (Up)
When Bypass LED is NOT illuminated,
TCC is commanded to NOT lock
PLAIN ENGLISH EXPLANATION:
The AlliLocker operation is simple. Leave it in normal mode until you want control of the torque converter clutch (TCC). When you engage bypass mode (left rocker switch) the TCC is completely controlled by the push button on the right (it is a latching push button). If you press it down it locks the TCC and stays locked until you push it again which raises the switch back to the open/unlocked position.
IMPORTANT NOTES:
• This product is intended for closed course race use only. Do NOT use on public roadways.
• Always disengage the bypass switch and unlatch the lock switch when not in use.
