• Scan, record and clear all codes before removing the original unit.
  
• Replace all seals.
• Install new filter kit.
• Flush and inspect cooling lines.
• Transmission cooler must be replaced regardless of condition.

• Engine or transmission damage as a result of improper installation is not covered. (i.e. dry sump engine w/o proper oiling equipment, Wet-sump engine used in rear engine layout or used for track conditions without proper oiling equipment installed).
• Verify that accessories and exhaust will fit your application before installation. Oil pans, starters, intakes and accessory drives may have to be changed out for an appropriate unit in order to function properly. (i.e. many newer engines do not have power steering pumps, this may have to be added by utilizing a specialized accessory drive, Dry sump corvette or camaro type engines will require an aftermarket dry sump system, Many late-model engines may require several accessories and Ecu/Tcm programming in order to work correctly, motor and transmission mounts, custom drive shafts, adapters, custom exhaust equipment, etc.).

We do not provide that type of support at this time. Late model engines and transmissions must be programmed before starting for the first time, failure to perform this procedure can cause damage and is not covered under your warranty.
• Make sure your harnesses are correctly installed, verified by a certified technician, before attempting to start your vehicle.
