did you replace vacuum switch on top of transfer case? They go bad and worst case they send ATF into every single HVAC actuator (big job replacing) and the front axle actuator.
No ,didn"t replace the vacuum switch don"t know much about these things or 4x4s.Wife bought this thing without me and the first thing I had to do was to re build the frount end ,ball joints a frame bushings pitman arm and iddeler arm. 4new tires, the rear had 2deffert sizes ,you know what that means.
The oldes one drives it and I haven"t figerd out how she killed the engine and trans at the same time.
Used the jack and block of wood ,didn"t take the left mount loose barly worked it through .

Today changed the spark plugs, 3x platinum, set gap at 60, old plug were 80+. Put exast manaflod on bolt up y pipe.
also freed up the flair nut on the egr tube and reused it.
