Jeep JL 392 8HP75 & 4xE Hybrid TO ATLAS

Jeep and Ram have several versions of there 8HP transmission, we have seen 5 variations to this series of transmissions so far. The differences are spline counts and lengths as well as bolt patterns. 

Jeep JL 392: These Jeeps have a full-time transfer case with an 8HP75 or 8HP75PH transmission. This transmission has a 43-spline output shaft and an adapter that is part of the stock transfer case. This adapter kit couples to this transmission and allows you to install an Atlas 23 spline input to the 8HP75/8HP75PH transmission. 

This kit is also used on the Jeep Hybrid which has the part time transfer case.
