The transfer case is a full-time/part-time NV242 from an XJ Cherokee. It sports a Currie SYE and Tera 4:1 low range gearing. Phil is a firm believer in full-time 4WD for winter driving. In our opinion, this versatile T-case is one of the best ever offered in a lightweight Jeep. The AX-15 transmission in front of the NV242 has gears from a diesel truck that give it a 4.3:1 first gear instead of the standard YJ 3.8:1. Phil changed to the AX-15 from the original Peugeot tranny to get rid of the problematic HydraClutch throwout bearing and use the later hydraulic slave cylinder.
