The Chrysler NSG370 is a six-speed overdrive manual transmission sourced from Mercedes and built in the Stuttgart Transmission Plant. It is Jeep's first six-speed manual transmission and Chrysler's second after the Dodge Viper T-56.
The NSG370 does not use standard gear oil for lubrication. This transmission utilizes bronze synchronizer collars resulting in sensitivity to lubricant make-up. Only a fluid characterized by Chrysler specification MS-9224 should be used in order to avoid premature wear or failure of internal parts as well as voiding the factory warranty. Pennzoil Synchromesh is one such petroleum based lubricant.
Common synthetic alternatives to the factory Mopar-branded conventional lubricant are Royal Purple's Synchromax and Red Line Oil's MTL. The synthetic alternatives often improve shifting performance while decreasing internal wear and noise. Transmissions from Jeep wranglers Length: 23.5" (I6), 24.8" (V6).
