PLEASE READ ENTIRE LISTING AND HAVE YOUR VIN READY BEFORE YOU BUY. THANK YOU. This listing is for a NEW Allison TCM (transmission control module) programmed for your VIN, which replaces all of the following Allison TCMs for 06-08 LLY/LBZ/LMM 6.6TD Duramax and L18 Silverado/Sierra 2500/3500 pickup trucks: A40 (11517030, 25798264, 29545321, 29544772) A46 (25982143, 29546675) T14A (24256864, 19431597, 24256671, 19434407, 24043956) You will receive a new TCM from the above list (typically A46 or T14A, but may be any of the above) programmed for your truck. PLEASE NOTE: The TCMs in this listing are for pickup trucks ONLY (2500/3500 Sierra/Silverado). If you have an 06+ Medium Duty truck (C4500/C5500+) or Workhorse Chassis RV, this listing is not for your vehicle. For those vehicles please contact us with your VIN and photo of your old original TCM and we will help you. IMPORTANT: This TCM requires programming with correct calibration for your vehicle, which is included in this listing: After purchase please send us an Ebay message with your VIN and we will program it. You need only disconnect battery, install TCM, reconnect battery and drive the vehicle -- no programming or otherprocedures will be required after installation. The TCM auto-learns. Any initial idle instability and shift idiosyncrasies are transient and will disappear on its own. To avoid delays in processing your order please (1) 1st confirm that the VIN is valid and (2) send it to us as soon as possible. SHIPPING: FREE UPS Ground. UPS Next Day Air Saver is also available at checkout for $45 if you need it faster. The processing time (1-2 business days) does not change. WARRANTY: If ECU fails within 30 days of delivery contact us and we will exchange it for a new replacement unit, buyer pays shipping. All ECUs must be installed by professional automotive technician into the correct, unmodified, application vehicle that it was ordered for. All ECUs must be returned in same unaltered condition as they are received. Any alteration to the form or function of the ECU, which includes but is not limited to opening or (re)programming it, voids the warranty. This is a part warranty, not an Ebay return policy. Due to buyers abusing the Ebay return system, we no longer have any return policy and do not accept returns. We are not a free troubleshooting ECU loaner service -- you cannot install and use our ECU to determine that your problem was something else, and return it because you don't need it anymore. You are responsible for accurately diagnosing your vehicle's requirements. Please make certain that you in fact need an ECU before you purchase it -- there are no returns/refunds. ECM = engine control module TCM = transmission control module BCM = body control module ECU = electronic control unit, including all of the above
