I am in the process of swapping a Cummins crate engine R2.8 diesel into my 1997 Jeep Wrangler TJ. The AX15 has a torque rating of 300 ft lbs, the little Cummins puts out 310, so it's close, but I want as much protection for the gears in the transmission, especially 5th gear due to the torque and also the possibility of turning up the power a little and might be at close to 400 ft lbs. Right now I am looking at Redline 75/90NS gl5, this is designed for transaxles to also allow manual transmission use hence the no slip designation. Any thoughts?
75W90NS GL-5 Gear Oil
Designed for transmissions and transaxles - helps to slow synchros for easier shifting across a broad temperature range
