95 chevy k1500 i put the truck in 4 wheel drive and heard a grinding then the truck moved alittle bit and lost reverse. Then lost all forward gears. could it be the transfer case or tranny

Hi Alex W, chevy k1500 A/T box? 4L80? sure 4wd,
get it checked out in a real shop?
we can not do the checks here, nor hear it
we would use and electronics, stethoscope to find
it zero risk to human body.
not told you, will it grind, parked , and makes noise
in all PRNDL selections, 2H mode.
or shift to 4wd neutral does it make noise"
my guess is only moving it makes noise!?
if yes tests can be dangerous to the tech and others.
is transfer case NP208 transfer case?
see this N here/
we can shift to N to see of noise ends.
a loose chain in the box below can make noise for sure using 4wd on dry pavement.

NI is for towing mode, see in the users guide. yours.

check for metal on the drain plug magnet and if you find any pull the transfer case

Failed Transmission Again

Part with it

Get something else

Maybe American (Rear Wheel Drive Only)

it is only suppose to go in 4 wheel when in park. when it is in drive the transfere case is spinning ,and it will damage it

is the drive shaft rotate when in gear?rear shaft or front rotate??

the rod you mentioned is called linkage, yes it's posible, snow may have jammed up under the car and is stopping it from properly engageing, or the grinding could be internal in the transmition, jack the car up, put jack stands under the frame,block the tiers, and take a real good look at were the linckage conects to the tranny, good luck

Do you have the tranfer case in gear?

Is your 4x4 light coming on? Does the shifter move smoothly into position? I have a 95 that I have just about had every proplem imaginable. Need morre info. John.

U are going to have to have the trans torn down and replace the reverse clutch drum.

the connections near the front axle that activate the motor to engage the system aren't melted? That's a comon problem for that body style. If there good, sounds like it could be that motor itself. To figure out if it's you motor or transfercase, jack up the rear end, have a friend inside shift into 4 wheel drive, or try to, and put it in gear and apply some gas. If the front driveshaft is turning then it's something with the front end. If not, farther back in the system.
