2001 Chevrolet Blazer Question: automatic transfer case hard shafting

 

Question

I have a problm with my automatic transfer case on my vehicle. It was in 4LD, and I could not get it back into 2HI, without playing with it for a very long time. I taken it to Fire Stone to have it looked at, and was told that it may be the computer that controls it, but thier can not be sure. I was advised to take it to a dealership to be looked at, because the computer is very costly, and they would not want replace it if it didn't need to be.
Have anyone else run into this kind of problm, and if so was it costly to fix?

    FIRESTONE GAVE YOU A B.S. ANSWER IN ORDER FOR YOU TO TAKE IT TO SOMEONE MORE QUALIFIED IN THESE REPAIRS.
    THE TRANSFER CASE SHIFT SOLENOID IS THE MOST LIKELY CAUSE. THEY ARE PRONE TO STICKING COMMONLY IN COLD, HUMID AND SALTY (NEAR OCEAN) AREAS. IF IT IS LONG PERIODS BETWEEN ENGAGEMENTS, IT CAN DEVELOP A THIN LAYER
    OF RUST ON PISTON OR IN SALTY AREAS THE ELECTRICAL CONTACTS WILL CORRODE. THE OTHER COMMON PROBLEM IS BINDING, IF YOUR ON AN INCLINE WHILE MAKING THE SWITCH, THE GEARS CAN BIND. SIMPLY CHANGING POSITION FORWARD OR BACK CAN CHANGE THIS EFFECT. GOOD LUCK.

    Be sure that you have the same size tires on all 4 wheels - I know this sounds elementary but I've seen it and it makes it really tough to shift out of 4WD
