IF ANYTHING ON THE REPLACEMENT TRANSMISSION APPEARS DIFFERENT FROM YOUR ORIGINAL UNIT, CONTACT US BEFORE INSTALLATION. INSTALLATION, PROGRAMMING & RELEARN REQUIREMENTS
Professional installation by a qualified automotive repair facility is required.
Before and during installation, the installer must:
- Compare the replacement transmission to the original before installation
- Verify transmission identification, RPO codes, GM numbers, connectors, and output configuration
- Verify proper torque-converter installation and engagement
- Use the correct GM-specified automatic transmission fluid
- Replace applicable seals, gaskets, filters, O-rings, and one-time-use components
- Properly flush or replace transmission cooler and cooler lines where applicable
- Confirm proper cooler flow before operating the vehicle
- Perform all required TCM programming and vehicle setup procedures
- Perform applicable transmission adaptive reset and relearn procedures
- Perform applicable GM Fast Learn procedures when required
- Follow GM-approved fluid filling and fluid-level procedures
- Correct all related engine, electrical, wiring, cooling, sensor, and control-module faults
