I have a 2005 gmc z71 1500 sierra that recently blew out the rearend and transmission practically at the same time.....is this common? Also I have been having trouble with the electronic 4 wheel drive and was wondering if it was possible to eliminate the electronic push buttons and change it over to a manual floor lever type and what would be involved in doing this. thank-you jeff

if you nuked the transmission the transfer case won't work....it is not very common to nuke a rear end and trans....yes you can switch the buttons to a floor shifter but its a ton of work...

It is very strange to lose the rear end and the transmission all at the same time. Like Jro said, it is a lot of work to change to manual 4wd. What kind of trouble are you having with electronic 4wd? It is not uncommon to have trouble with the 4wd actuator. Often times these need to be replaced if you are having issues.

We are thinking when the rear end locked up it broke something in the transmission,rear end is fixed now transmission needs to be done.

The 4wd. has been acting funny for awhile now been told it's probably the electric motor on the side of the transfer case I assume this is what you are calling the actuator? They are anywhere from $400 and up around here depending what you get (junk yard or new) but if that's going to keep recurring it may be cheaper in the long run to change it over.

What exactly do you mean by acting funny? What happens when you press the button to change into 4Hi or 4Lo. Does the light blink and stay on Auto or does it change and light up on the button you pressed? Do you hear any noises?

The light would hange from 2wheel to 4 wheel hi or low while driving,I would start the truck and look at the lights and it would say it was in 4lo shift to neutral press 2wheel button hear the normal sound of it shifting to 2wheel and it would be fine and a bunch of different things like that......had it scanned no codes would come up learned to be very aware of what those lights were on

yes the lights on occasion would blnk or show it was in neutral as well as go out alltogether

Could also be a faulty switch. I worked in the parts department for a Chevy dealership for several years and these switches were a very common problem, we replaced a lot of them. Could be something as simple as that. That certainly would be nice for you because it is an easier fix. Hard to say though. I'm sorry I can't be of more help to you though!

Changed the switch all ready no difference,probably the safest and cheapest in the long run to change back to manual shift.Thanks for the help.

thats a whole hell of alot of work to change it over to the lever....probably would be cheaper to just have a tech fix your 4x4

by actutor do you mean the motor on the side of the transfercase?The prices for that I got from dealers and junk yards

I don't know where you've been looking, but an actuator doesn't cost 400 bucks.

Have a look at these actuators, one goes on the front diff and one on the transfer case, depending on which one of yours is broken.

you cant really put a life span on a part, an actuator could last for an hour or a decade....swapping to the floor lever would involve cutting into the floor...tinkering with the computer..taking parts out..adding linkage...your high if you think going to manuel 4x4 is cheaper then fixing the electronic 4x4

      The Peckish Synapse

      By Grumpy Bear · Posted

      You're better read than that Atlas. 😏   British science fiction writer Arthur C. Clarke formulated three adages that are known as Clarke's three laws, of which the third law – that "any sufficiently advanced technology is indistinguishable from magic" – is the best known and most widely cited.   Stribeck and the pivotable Hersey Number isn't voodoo nor snake oil. That part is physics. It's what marketing and bean counters do with it that is snake oil and voodoo.    Stribeck is the relationship between Hersey and the Coefficient of Friction. Within the Hersey Equation if viscosity and viscosity is 'Dependent' on.......heat.......and.......viscosity index or the temperature to viscosity slope.    Specifically Hersey is the viscosity AT THE TEMPERATURE IN THAT LOCATION FOR THAT SLOPE.   Hydrodynamic lubrication exist when the film thickness in the location is 3X the Ra roughness of the surface. This is irrespective of the hardness of the substrate. To obtain that thickness X viscosity is required for Y velocity at Z load. That's a lot of moving parts. It is also impossible to maintain in an ICE but nearly possible with a turbine under constant load.    What does that mean? Error heavy and operate light. Wear is inevitable but the rate of wear and the milage obtainable are a function of prevailing conditions and HABITS. The only penalty is viscous drag and at fractions so low as to be well worth the effort. Double the life, half the manufacturing carbon foot print. Greed is the only impediment.    The materials generated by SwRI are the RESULT not an estimation or a hypothesis.    Don't delude yourself sir, EV's have as many pitfalls as ICE's. We just don't know what they are yet and it will take longer to sort as MARKETING and GREEDY CEO's have had more time to polish the turd they are selling.

      You can always count on greed to prey on ignorance and stupidity.    Friend bought a 2019 Ford Flex and asked me about using Valvoline R&P 5W30 in it. Told him give the miles on it and the fact it wasn't yet using oil that it was a good plan. He uses a Valvoline quick change shop for his oil service.   First they tell him that isn't the oil the OEM recommends. He told them he didn't care what the OEM thought. Then they floated the, "But it will void your warranty"    His reply was it's a 2019, there is no warranty and informed them their knowledge of the law was lacking.    Then they tell him 'But it will ruin your motor"!.    Mine to ruin he says. Finally they give in and charge him 150% the semi-syn price    Point it the brainwash is so embedded that even the service industry is drunk on their swill. The public is right behind them. Echoing the same lies on every forum and media platform. If the end goal is indeed EV then I'd say that ship is about built.
