Re: 91 trooper stuck in neutral
Possible range selection detent switch not working causing to get stuck some times in one range only and wont shift to other range 4wd light in dash just keeps flashing for about 10 seconds then goes to previous state this then can jam up 2wd 4wd lever that you then cannot move.
there are 3 switches 2 on trans/transferr case, 1 on front LH diff axle tube actuator (shift on fly). can cause damge to the electric actuator then on transferr case.
suggest you get a dealer to look at or some one that knows this system. is also vaccum operated on front diff shift on fly unit and there were 2 different systems fitted to these vehicles push button 4wd on dash and lever next to gear lever which i take is yours

the transmission and the transfer case are two different parts. the transfer case takes the shaft power and splits it to the front and back. depending on the cable or electric motor that shifts the transfer case gears. you could have a problem with just an electric motor or cable and or the transfer case it self could be the problem. try putting the truck into neutral before trying the high and low to make it easier to work and hope it goes. the second thing is are the rear wheels working in 2wd or in 4wd or is just the front wheels working in 4wd.
4wd auto: you can shift into this mode at anytime. it is good for conditions where you might need 4wd.
4wdhi:: you can shift into this at speeds up to 30mph and both of these back to 2wd while in gear.
4wd lo : stop vehicle and shift truck into nuetral ok to be rolling around 3mph shift into 4lo then put in gear same when shifting back to 2wd
Place the transmission in Neutral and try to get it back in to 4 hi or 2wd. You can also place the transmission in neutral and then turn the engine off and try to get it in to 4 hi or 2wd and you should hear the transfer case electric encoder motor shift from 4 lo to the other gears. If you don't check the fuse in the fuse panel, it may have blown. Good luck and keep me posted.
Ok here is a long shot but sometimes it will work. Put the 4wd position switch to 4wd Lo, put your transmission in reverse and back up for about 50 yards, stop and put your transmission in neutral, then shift the 4wd to 4wd hi, wait a few seconds and shift the 4wd to 2wd hi, Sometimes the t-case will get stuck and this is how you reset the computer. I have known people that really got their t-cases messed up because they thought that shift on the go meant that they could shift the t-case into 4wd LO while moving but shift on the go is only for 4wd hi the gears will not mesh up fast enough for 4wd LO because the ratio is 1 to 1 . I hope this helps you.
make sure your 4WD switch is working.and fuse is okay.because your 4WD is control by 4 electric shift motors in which drive a rotary cam which moves the mode fork and range fork inside the transfer case to select between 2WD HIGH A4WD - 4WD HIGH AND 4WD LOW RANGE.a shift motor sensing plate on the shift motor monitors the range in which the transfer case is operating a transmission range sensor monitors the gear position of the transmission.which must be in neutral to shift into low.a pair of solenoids one for 2WD one for 4WD.mounted on the upper right firewall route vacuum to the vacuum motor which engages and disengages the center axle disconnect collar in the front axle assembly.a 4 x 4 shift motor relay module contains two GEM controlled relays which shift the transfer case shift motor between 2WD and 4WD modes.a solid state clutch relay activates the A4WDclutch inside the transfer case.
