Our warranty is 1 year unlimited mileage limited to Repair of our Unit, Replacement or Credit. Shipping fees and some programming and processing fees may not be refundable.

Any and All Problems with the vehicle must be repaired and resolved before re-installation. We are not responsible for damage to our product due to improper installation or existing issues unresolved that damage the ECM Engine Computer. Be sure Charging system is Good. Many times we see problems with the transmission shifting. They are often caused by harness failure or shorting. This is a common problem with the Wranglers. Any low voltage events can damage the ECM. Any shorts such as inverting battery or short in Power or Ground, short in Alternator can affect the ECM. Wiring Harness shorts are common problem. The Engine shakes and the Mounting Brackets rub against the Harness for years until insulation is compromised or damaged which can lead to voltage loss or shorts.
