I never got the t-case to shift smooth at higher speed than just rolling a bit. But what ever the question may rise please post it.

Simp you did it again thank you, you were right about the ground... The capacitor is grounded on transmission as well as the solenoid and I dont know if the ground was bad or the Transorb Diode was bad but now I am able to successfully shift from Lo to Hi on tcase while moving, but I get a...

I have found the TRANSMISSION 5TH-GEAR LOCKUP SOLENOID VALVE it was in a tight place behind that plate. I placed my hand on it and pressed the button on the tcase lever and it did click, I dont know if that means it is working or not, could it be just clicking but not opening?

Thank you for that info let me see if I can find where that is and trouble shoot it... If it is activated by the button on the shifter than it must be electronicly wired...

What swamp donkey has posted in operating manual, it says there is an another safety system called lock up solenoid that prevents tcase to switching gears unless the trans is in N, which mean s that solenoid can be defective or not receiving signal from the transmission, and that definatley is...

Now that raises another question for me, while moving trans in N, forget about getting the tcase shifting, I cant even put it in N, I was able to do that once or twice and when I got to the point when it was shifting Lo it started grinding noise, I even pressed gas pedal and than I heard...

While moving?

I was so hoping that I can shift it while moving, like throw the trans in N than switch Lo then throw the trans in gear again.

I dont have the NSN, the seals help, with the puking only, but hard shifting is continued, I am also still not able to change Hi n Lo gears in motion, while truck is moving, I might be able to figure out hard shiftin if there was a t-case nearby that I can brake into. It does feel like some...

I updated the original post with complete report.

Ok I did solve the problem and analyzed the causes, I will report in soon.

:popcorn: I just did cut off the air supply, put everything back together and waiting for tropical storm to calm down, the one that visits every day at 4 pm, I will test drive...

My range selector act the same way, but some times I have to be there for a minute jiggling around with handles, and I get a grinding sound when I put the trans in and out of gear while trying to align the gears trying to shift the range selector so it will shift, I use to think my air solenoid...

Ok I thought that was a seal, but you are right it has a flap on it, I haven't change that, I just broke into it, do you have the numbers to it?

Yes thank you, I dont understand what the flap is, is that something inside the air cylinder? NSN number for the push lock rod is 2520-01-134-7657 Cage 78500

OK so I had this issue, range selector being hard at shifting from and to low and high, also I had gear oil squirting from dash air switch for front axle engagement. First I found out all 3 t-case breather vent lines were plugged intentionally with small rubber pieces, per advice from forum...
