The Adapter
The Novak TH400 to Jeep NP / NVG transfer cases adapter is very compact at only 1.4-inches in length. This adapter assembly is the shortest Turbo 400 adapter in the industry, providing a combined transmission and adapter length of only 25.9-inches.
The adapter itself is cast and machined of a high-grade aluminum alloy, featuring thick flanges and a heavy cross-section.

TH400 Versions
These kits are for all years and versions of the popular HydraMatic 400, including Chevy, Buick and other GM, AMC Jeep, etc. and work with 2wd & 4wd versions.

Transmission Output Shaft
Every kit comes with a new output shaft for the TH400, whether for 2wd or 4wd transmissions. 2wd versions work equally well as 4wd versions. The Novak output shaft is of an alloy steel, precision splined and hardened for a superior interchange. This shaft connects the TH400 output directly into the existing 23 spline NP transfer case input shaft for the strongest combination.
Installation requires disassembly of the transmission main assembly, and we recommend the services of a transmission professional. The basic installation is 3-4 hour bench job and may include simple gasket and seal replacements. Some choose this as the time for a more thorough transmission master rebuild and update.

Transfer Case Input Gears
The included Turbo 400 output shaft splines in directly into the OEM Jeep input gears, and transfer case disassembly is not typically required.

This kit also works with the Dana 300 Transfer Case Swaps (from the CJ models)
