The NV4500 transmission has a fifth gear design flaw, we have engineered a solution to easily upgrade your Dodge's NV-4500 Trans so you'll never worry about 5th gear failure again and will keep your tranny running smooth. Craftsman quality you can see: we designed our retainer to be complete with reinforced, extended splines attached to thick, sturdy walls that will lock the nut to the splines on the main shaft for good. You'll never experience the retaining nut backing off again. We then completed our solution by including an upgraded version of the Retaining Nut - our Retaining Nut has reinforced threads on a thick sturdy steel body and has a double locking screw set for maximum grip, just to reinforce 5th gear. You'll never experience a delay in responsiveness during shifting because our included spring washer will help control reaction under dynamic loads. We're so confident that this upgrade will solve 5th gear failure problems caused by the retaining nut backing off, our product is backed with an Limited Lifetime Warranty. That means if our product ever fails after it has been correctly installed, we'll replace the product 100% free of charge.
