Zumbrota Drivetrain RMTNSG370-10 NSG370 Remanufactured 6-Speed Manual Transmission

The Zumbrota Drivetrain RMTNSG370-10 is a remanufactured NSG370 6-speed manual transmission engineered for the 2007–2008 Jeep Wrangler equipped with the 3.8L V6 engine (2WD). The NSG370 — short for Neues Schaltgetriebe ("new manual shifting transmission") — was sourced from Mercedes-Benz and built at the Stuttgart Transmission Plant, representing Jeep's first-ever six-speed manual gearbox. Zumbrota Drivetrain remanufactures each unit to OEM specifications, delivering a reliable, like-new replacement at a fraction of the cost of a new OEM assembly.

Zumbrota 3-Step Remanufacturing Process:

• Step 1 – Pre-Inspection: Each core is inspected for case cracks, excessive wear, and OEM-specific problems before remanufacturing begins
• Step 2 – In-Process Inspection: All component parts are measured to confirm they meet OEM specifications
• Step 3 – Post-Build Inspection: Completed unit is verified to Zumbrota's exacting quality standards — shaft straightness, gear wear, and synchronizer performance are all tested

Additional Quality Processes:

• All seals are replaced during remanufacturing
• Units are dyno-tested for operation, shiftability, and noise level
• Exclusive hydro-blast rinse and sandblasting procedure restores cases to OEM finish
• Front and rear cases included with integral bellhousing

Warranty: Backed by Zumbrota's standard 2-year/unlimited mileage warranty (applicable to 3/4-ton and lighter applications).

Note: A refundable core charge applies at time of purchase. The original transmission must be returned to complete the core exchange. This unit requires Chrysler MS-9224 specification fluid — do not use standard gear oil, as the NSG370's bronze synchronizer collars are sensitive to lubricant composition.
