Description

Adapting the GM 4L60-E (later version) Transmission to the Jeep Dana Model 300 Transfer Case and Full-Size Jeep New Process Transfer Cases

Upgrade your Full Size Jeep drivetrain with this premium 4L60-E, 4L65-E, or 4L70-E to NP/NVG transfer case adapter kit—engineered for maximum strength, compactness, and seamless integration. Designed specifically for Full Size Jeep Wagoneer, Cherokee, Grand Wagoneer, J10, and J20 builds, this adapter is only 3.0" long, resulting in a total transmission and adapter assembly length of just 24.5".

Precision cast and machined from high-grade aluminum alloy, the adapter features thick flanges, a robust cross-section, and added gussets for long-term durability in demanding applications.

Transmission Compatibility:
This kit fits all 4L60-E, 4L65-E, and 4L70-E transmissions (both 2WD and 4WD versions) with the hexagonal six-bolt tailhousing—common on 1996 and newer models. Early 1997 and previous transmissions with a four-bolt pattern and non-removable bellhousing are not compatible.

Easy Output Shaft Integration:
Each kit includes a hardened alloy steel output shaft, precision-splined for the strongest possible connection. This shaft links your GM transmission directly to a 23-spline NP/NVG input shaft—providing maximum strength and a direct fit. Both 2WD and 4WD versions of the transmission are supported equally well.

Installation Notes:
Professional transmission assembly is recommended, though skilled home mechanics can accomplish the installation. Expect a 3–4 hour bench job, with the opportunity to replace seals or perform a full rebuild if desired. Transfer case disassembly is generally not needed, as the output shaft splines directly into the factory Jeep input gear.

Integrated Speed Sensor:
For seamless engine management and factory gauge compatibility, the adapter assembly integrates a Vehicle Speed Sensor (VSS) for the 4L60-E’s computer system. The Jeep speedometer cable or VSS can connect directly to your original gauge panel, maintaining OEM functionality.
