Consumers of aftermarket products are protected by The Federal Magnusson Moss Warranty Act The Act states that if something breaks on your car and you take it in for warranty repair the dealer must honor your warranty unless they can prove that whatever modifications you have added to your car actually caused the problem Please keep in mind that towing in anything higher than level two and hard driving in levels four and five are not recommended While as a consumer you have strong legal protection with regards to your vehicle s warranty there is also a practical reality that different automotive manufacturers and dealers have greatly varying views on aftermarket products in particular those that produce horsepower such as performance enhancement chips modified intake manifolds or aftermarket exhaust systems There are dealers and manufacturers out there that will use the presence of a horsepower upgrade to void your vehicle s warranty They will do this regardless of whose product you are using Any aftermarket company that does not acknowledge this is misleading you The bottom line is that while the law protects the consumer and provides for enforcement of the warranty it is very difficult for most people to hire an attorney and fight a voided warranty Edge recommends that you always disconnect and remove your module and monitor when you take your vehicle to a dealer for warranty work in order not to interfere with Diagnostic equipme

Pulling up a hill for several minutes at 1400 is far worse As you drive your truck in the various power settings keep your eye on the EGTs Depending on how you drive and where you drive you may find a particular power level is more suitable to your power needs The Juice Module and your Transmission The automatic transmission has a fluid filled clutch like device called a torque converter This device uses the spinning motion of the motor to drive the transmission which drives your wheels As the truck speed stabilizes the torque converter engages a mechanical connection which locks the two halves of the torque converter so the output shaft 1s going the same speed as the input shaft This mechanical linking of the two halves is called Transmission Lock up If the motor produces too much power this mechanical lock up can start to slip When this slippage occurs the Juice module reduces the power output to allow the transmission to function properly This is a great future that provides an extra level of protection for your vehicle Please keep in mind however that if you run in level 4 or 5 the additional power is so great that it is possible to overstress a stock Allison transmission if you drive too hard Edge on your Side Edge takes a great deal of pride in the quality of our customer service If you 12 GM Juice Attitude Manual Edge Products LLC have any questions or concerns about your Juice module please feel free to cal
