It keeps blowing the fuse for the transmission,when i put it in gear the fuse blows and the car is stuck in one gear,it is the 4 clcyle with the slap stick to change gears.

Check your wiring in the circuit going to the actuator. You may have a short due to a rubbed wire with iunsulation missing.

isolate the reason for the dead short that keeps blowing the fuse. Look for a broken wire under body on a actuator or a wire that has rubbed through on the transmission .

Question are you putting in the correct size fuse ? Look in the owners Manuel it will tell you what amp fuse goes where. May be as simple as that always make sure you put the same amp fuse back in very important.

GMC and Chevy has issues with the dash controls on 4WD models

u will have to find out what all is on that fuse and find the short

check all the fuses before you do anything else. After all a fuse provides power to the electronic box that controls the transmission. Other than that I would not advice on a more complicated troubleshooting since there is no way for you to test a bad transmission computer, even mechanic shops don't know how to test them. The only thing they would do is slap a known good one and see what happens.

Sounds like you have a wiring problem. May want to begin by determining which circuit is causing your fuse to blow. If you are not mechanically inclined, I recommend you take if to a trust worthy repair shop.

hmm. lt look like there are poor joints in your wiring specially the groung wire. check the diagram of your auto. check the unit diagram for which the fuse blows. usually the fuse blow when there is a short circuit. if you look around you will find it.
good luck

there could be chaffed wires that r grounding

dead short in wiring, maybe or fan moter is stuck or will not turn causing fuse to blow? can you smell wiring getting hot> or brushes shorting in fan moter.
