Y do u need 2 buttons 2 use 4wd on 05 gmc


I have a 2003 GMC it has two buttons to use 4 wheel drive as most all do with push button controls...One is for standard highway driving with 4 wheel drive the other is for 4 wheel drive a low speeds for off road driving and conditions that need low speed less spin driving..not designed for highway use..and must be stopped to engage where 4 speed highway can be shifted on the go..hope this answers your question..good luck..

I have a 86 gmc s -15 and I need to shift it from 2 low to 2 high - it would save gas I believe, how do I do this correctly?


Most shifts can be done on the fly by moving the selector breaking the power by lift ting the foot of the gas for a sec.. To really save on gas have locking hubs fitted to the front wheels and in the unlock position the vehicle is like a 2 wheel drive vehicle. Check the operators manual or down load it from the GHM web site.

I have a 2000 gmc and my 4-wheel drive will not lock in. the actuator and transfer case are engaging but the wheels are not locking in. What should i look forto see what the problem is?


Ihave the manuals for up to 99 but i don't think chevy changed the system ot 2000 . The unit is vacuum opperated and when the drive gear inside the transaxle is engaged the wheels will spin there is no locking hub involved in the system witch means the problem is coming from behind that system . Ineed to read somethings in the manual but the games are coming on so i will get back to you later to day with an answer And what else dose it or dosen't do reguard the 4 wheel what dose the shift indicator light indiacte and are you getting any codes there is a lot of wireing to do with the transfer case and how it interacts with the transmission

Four wheel drive stuck in neutral. Won't go into 2high or back to 4 wheel drive. Transfer case was replaced. Its a 2000 Jimmy.


If you have the push buttons on the dash board you must follow the instructions in your owners manual to return the transfer case to 2wd from neutral. I don't remember for sure but I think you must have the transmission in neutral, foot on brake, press and hold both 2wd and 4wdlow buttons at same time. My father who lives 45 miles from me has the Jimmy, I don't. Hope this helps, Jim
