Away!
Well, vehicle has a clean bill of health.
Both diff fluids were changed
transmission fluid and filter changed
Brakes replaced
front transfer case motor replaced
valve cover gaskets replaced and heads inspected visually
Coolant leak was a plastic fitting by the firewall for the heater core
The Limited Slip Differential clutch material are worn and need new friction material (on order and will be replaced, super common in Alaska apparently).
Drove it 30 miles and so far no dash messages and everything seems to work as it should, even the transmission isn't slipping anymore... Need to drive it more as the 1-2 shift is still super firm. I have a new valve body in case the current one needs to be replaced. The shop suggested I drive it around for a while and when he gets the stuff for the LSD he will call me and if the valve body needs to be replaced he will do it at that time.
We traded work, so cost was $0!
Best $1500 I have ever spent on a vehicle.
Great news!
