96 chevy tahoe 4x4 transfer and transmition problem

Sounds like a 4x4 encoder motor problem.

my 2001 chevy silverado would not swich some time and with a lot of agravation of repeat pushing of the buttons. change out the 4x4 switches in the dash solved the problem, the orginal switches soldering cracked makeing for bad connections "transfer case switch" Auto parts warehouse

is the transfer case shifted into neutral?what if you move it down to low gear?is there fluid?

Depending on if you have a push button, switch activated, or manual shift type 4x4 system they are generally the same. Transfer in 4x4 high can generally be made at any time that you're not traveling at highway speeds or faster by simply moving/pressing the selector switch/lever/button to the position indicated as 4x4 high. If you are wanting to use 4x4 low this transfer has to be made while the vehicle is stationary, wheels straight, vehicle in neutral and brake depressed. Note that the use of 4x4 low is only recommended for the most extreme driving conditions and should only be operated at low speeds.

turn 4x4 switch off put vehicle in neutral then put vehicle in reverse and drive in reverse a couple of feet the put it into drive and it should come off of 4x4 if not then repeat until it comes off

then the seloniod actuator if the front diff may be bad, this is common,heres a diagram to show you what it is and where it is, hope this helps.

Ive seen the motor go bad that turn it to 4 low to 4 high on the transfer case

The key distinction of the Later 4L60-E (1997-2006) from the Early 4L60-E (1992-1997) or 4L60 (1990-1992) or 700R4 (1982-1989) is the six-bolt "hex" rear output or tail housing / adapter pattern. The previous versions featured a four-bolt square bolt pattern at the adapter or tail housing. This is where that made the small change and the 96/97 year was a change over year so you may have the newer housing or the older housing, but if your replacing the transfer case with the transmission your good to go, the electronics are the same. Just the body housing is different. Good luck and hope this helps. And why wold you want to convert the transmission, there are lots of easy simple up grades with out dropping the transmission or valve body. 

Go buy the chevrolet shop manual for the truck. Its worth every penny in the long run and will save you thousands by not going to the dealer for everything, because they consult the shop manual. make sure your tranny doesnt share fluid with your transfer case, you could over fill or underfill it easily.

Fluid Should Be Checked Just The Same As Engine Oil. Should Be Changed At Least Once A Year For Proper Service & Reliability. Should be Driven 10 Miles A Month In 4 Hi To Keep Lubricated. I Drive A 1975 Chevy K10 PKP FullTime 4X4 NP203 & A 1980 GMC Jimmy Lock-Outs 4X4 NP205, And I Drive Them Once A Month At 55 MPH For 10 Miles (On Pavement). Keeps The System Lubed Up & Moving. Have Done This For The Last 15 Years I Have Owned Them. KEEP THEM SERVICED. Low Oil Is A Transfer Case Killer. Also Put The Correct Type Of Fluid In, Each Transfer Case Takes A Different Type Of Fluid, Call Dealer Shop For Correct Fluid Type. Some Take Dextron III Or 10-40 Engine Oil Depends On Transfer Case.
