This connector integrates TCM power, ground, CAN bus, and solenoid control circuits for Toyota’s automatic transmission systems.

Key Specifications

Why Transmission Connectors Fail

Toyota transmission harness connectors are exposed to ATF (automatic transmission fluid) contamination, thermal cycling, and vibration from the gearbox. Terminal corrosion or fluid ingress causes harsh shifting, transmission slipping, limp mode, or P0700-series fault codes. Replacing the connector restores clean TCM signal paths and eliminates phantom transmission faults.

Variant Guide

• Black Female / Black Female 15CM – Black housing (standard configuration)
• A Grey Female / A Grey Female 15CM – Grey housing Type A configuration
• B Grey Female / B Grey Female 15CM – Grey housing Type B configuration

Select the color and type matching your OEM transmission harness connector. Cross-reference OEM 90980-12362 with your vehicle’s wiring diagram.

Installation Steps

1. Disconnect the vehicle battery
2. Access the transmission connector (may require partial transmission removal or drain)
3. Use a terminal extraction tool to remove terminals from the original housing
4. Transfer terminals to the new housing maintaining exact pin positions
5. Reconnect and use Toyota Techstream to clear transmission fault codes
6. Perform a transmission adaptation reset if required

Frequently Asked Questions

Q: What Toyota models use OEM 90980-12362?
A: This connector is used on Toyota Camry, Corolla, RAV4, Highlander, Land Cruiser, and Lexus ES/IS/GS with automatic transmissions. Cross-reference your vehicle’s wiring diagram to confirm fitment.

Q: What fault codes indicate a failed transmission connector?
A: Common codes include P0700 (TCM malfunction), P0715–P0720 (speed sensor faults), P0730–P0736 (incorrect gear ratio), and U0101 (lost communication with TCM) on Toyota Techstream.
