LB7 ECM / Allison 5-Speed TCM Terminals, 5 Pack | 2001-2005

LB7 ECM / Allison 5-Speed TCM Terminals, 5 Pack | 2001-2005

These replacement terminals (pins) fit the ECM connectors on the 2001-2004 6.6L Duramax LB7 and the TCM connectors for the 2001-2005 Allison 5-speed transmission. They are Aptiv (Delphi) 12084912 Micro-Pack 100W gold-plated, unsealed female terminals for 18 AWG wire. Use them to repair a connector with corroded, spread or damaged pins, a common cause of intermittent stalling, no-start, communication codes or erratic shifting.

Key Features

• Aptiv (Delphi) 12084912 terminal
• Micro-Pack 100W series, female, unsealed
• Gold-plated contacts
• For 18 AWG wire
• Sold as a 5 pack

Benefits

A single bad pin at the ECM or TCM can cause problems that look like a failed module. Replacing just the damaged terminals restores a solid connection without replacing the whole harness or connector. The gold plating resists the corrosion that causes many of these failures in the first place. Replace if worn or damaged.

Frequently Asked Questions

Do these fit the LLY ECM?
No. These fit the LB7 ECM connectors. They fit the 2004.5-2005 LLY trucks only at the Allison 5-speed TCM connector.

How many come in a pack?
Each pack has 5 terminals. Order more packs if you're replacing several pins.

Do I need special tools?
Installing a new terminal requires removing the old pin from the connector and crimping the new one onto the wire. Use a terminal release tool and a crimper made for Micro-Pack terminals.

Fitment

Fits the ECM connectors on 2001-2004 Chevrolet Silverado and GMC Sierra 2500HD and 3500 with the 6.6L Duramax LB7, and the TCM connectors on 2001-2005 trucks with the Allison 5-speed transmission (LB7 and LLY).
