Fire, etc
So it turns out it had nothing to do with lack of low-range or overworking the transmission.
When I had Robson Racing installing my ARB locker I had them also change my ATF, only when they put the pan back on they cut the gasket. It only leaked once the vehicle was brought nose-up so it went unnoticed for awhile. The slab where it had trouble was high-angle and the leak drained directly onto the Y-Pipe leading to the fire.
The good news is I replaced the gasket and all is fine, I also hooked up the 2nd interlock solenoid for the transfer case (long story but it has to do with having 2001 and 2004 parts on a 2003 vehicle) and high-low shifting works great now.
I'm waiting on a computer interface to arrive (any day now) so I can reset the ABS codes and get my traction control back, which will make the Eaton TrueTrac in the front Diff a lot more useful.
Also adding sway bar disconnects, my articulation was not very impressive with both swaybars connected. Hopefully in about 2 weeks the quick disconnects will be in place. I'm also investigating a coilover conversion but also found out today that I need a new valley gasket which will take some of the money I was planning for suspension so who knows.
Looking forward to the next outing.
