Mercedes 722.6 Shift Solenoid Upgrade and Transmission Service (NAG1)

Video Description

►The 722.6 5-speed automatic transmission, also known as the NAG1, was designed by Mercedes-Benz and was used in a host of vehicles. This transmission was factory equipment in a host of Mercedes vehicles for over a decade and even found its way into several vehicles from Jeep, Dodge, Jaguar, and Porsche models during this time. Installing Genuine Mercedes "Blue Top" shift solenoids in place of factory-equipped "brown top" solenoids is a common upgrade for faster and firmer shifts. Delivering increased shift pressure and speed through high-flow solenoids, the "Blue Top" solenoids pair incredibly well with an aftermarket transmission tune. To upgrade the NAG1 shift solenoids, the valve body must be removed from the transmission. While it's apart, a full service is recommended. This guide assists in installing "blue top" solenoids but also walks 722.6 owners through a complete 722.6 service, including solenoid replacement, conductor plate replacement, overlap sleeve replacement, and fluid and filter replacement. In this DIY, Danny Kruger, FCP Euro's Mercedes Expert, leads us through the removal of the valve body, the replacement of the conductor Plate, and also the replacement of the torque converter clutch lockup solenoid (also known as the TCC solenoid) as these are common weak points of the 722.6 NAG1.
