Stellar Automotive Group 4L60E Internal Harness w/Lock-up Solenoid – Compatible for GM 1993-Up

Fix no torque converter lock-up, erratic shifting, and common solenoid codes with this complete internal harness and lock-up solenoid assembly from Stellar Automotive Group.

The factory internal harness is notorious for chafing, broken wires, and corroded connectors — causing intermittent solenoid signals, no TCC lock-up, harsh shifts, or limp mode. This direct-replacement harness includes a pre-installed upgraded lock-up (TCC) solenoid with improved wiring and sealed connectors for long-term reliability.

Perfect fit for popular 1993-Up models including:

• Chevrolet Silverado, Tahoe, Suburban, Camaro, Corvette
• GMC Sierra, Yukon, Jimmy
• Cadillac Escalade

Common issues this harness resolves:

• No torque converter lock-up or shudder
• Harsh or delayed shifts
• Slipping in overdrive
• P0741, P0751, P1860 solenoid/TCC codes

Easy installation – drop the pan, unplug the old harness, plug in the new one, and reinstall the valve body. No soldering required.

Note: All parts are distributed, not designed or manufactured, by Stellar Automotive Group.
