Engine Control Module (Also known as PCM. ECM, ECU, TCM or TCU) for the 2006-2007 Jeep Wrangler with 4.0L, L6 engine and automatic transmission (A/T). This ECM is “Plug and Play” with our FREE VIN number programming service. Please go on reading below for more information.
SYMPTOMS
These 2006 Jeep Wrangler 4.0L automatic models are commonly having issues with the automatic transmission (Automatic 42RLE Transmission), where it shows erratic or harsh shifting and/or sluggish movements when accelerating after completely stopping, among other transmission symptoms and most of the times, the system gives no error or trouble codes. This applies to Rubicon, SE, Sport, Unlimited, Unlimited Sport, Unlimited Rubicon, TJ, 65th Anniversary Edition Sport, and all other submodels with a 4.0L engine.
If you experience the above-mentioned issues with your Wrangler, replacing the ECM with this one will solve the problem most of the times. If you keep using your vehicle with the described failure, the transmission will unavoidably suffer an internal failure that would require a costly transmission repair.
ABOUT THIS PART
Your vehicle mileage WILL NOT be affected by using this ECM.
This unit has been refurbished and reprogrammed. We are also including the extra service of programming the VIN number of your Wrangler to this ECM for FREE ($100 value). This is what will make it “plug and Play”, which means that you just install it and it is ready to use. No other programming needed. If you wish to add this free service, please just add your Wrangler VIN number (17 characters) in the appropriate form at the checkout page when ordering.
If you do not include the VIN number when you order, we will assume that you or your mechanic will program it and we will ship the unit without that extra service. If the case is that you forgot, just send us a message through our contact form on this website within 24 hours of ordering. After that time, your ECM will probably be already shipped.
IF YOU DO NOT INCLUDE YOUR VIN NUMBER, THE ECM WILL NOT START THE ENGINE UNTIL IT IS PROGRAMMED.
MAKE SURE YOU SEND THE VIN NUMBER CORRECTLY. PLEASE DOUBLE-CHECK IT.
Make sure that the part number shown here matches exactly with your part to be replaced before ordering. If your vehicle is a 2006 Jeep Wrangler 4.0L, automatic and your ECM has a different part number, please contact us with the details so we can advise if this part is compatible.
NOTE: Before ordering any parts for a vehicle that is showing transmission issues, always check first the transmission fluid levels and clearness of the fluid. Sometimes simple things like that solve big problems without the need for replacing any parts.
