Manual AWD switch???

Manual AWD switch???

Postby Onthewater01 [OP] » May 13th 2019, 2:55am

Has anyone ever tried switching the the AWD manually? You know a switch on the dash to manually activate the AWD transfer case? Or is this just a dumb idea?

I have to believe someone has tried this...

It's a great idea... it's been discussed on numerous occasions.. it could be easily done.. but as far as I know it can't reliably be done, and no one has done it. I almost wired mine manually.

The encoder motor that physically engages the AWD uses a PWM (pulse width modulated) signal. There are two main wires that feed it (from the controller).. they are easily accessible in the DS kick panel. It's feasible that this connection could be interrupted though a manual relay.. but it is also likely that continuous 12vdc would burn up the encoder motor. It would definitely give you manual AWD.. but for how long? It is also unclear how the clutch packs would react to a steady signal vs pulse-width modulated signal... but my guess this is probably not an issue.

I'm still waiting for the day when someone connects 12v to an old encoder motor to see how long it will last.

Of course if someone wanted to get clever, I see no reason why you could devise a a manual circuit that duplicates the PWM that the controller sends.

If you want manual 4x4... I highly recommend the bolt-on replacement NP233C transfer case! No clutches to go bad.. no controller to go bad.. no sensors to go bad.. no encoder motor to go bad.. just pull a lever and pure manual 4x4 operation... hi and lo range too. The conversion is fairly simple and inexpensive, completely bolt-on... and 100% rock solid. :D

Pulse width...interesting....like maybe hook up a 110v inverter, then a transformer to drop it back down to 24v a.c., then run it through a rectifier to to clip the sine wave to 12v d.c. pulses???

If you want to lock your tc I think your best bet is to use the encoder motor from the np236. It bolts right up to our np136. The 236 encoder has an electric brake that locks the clutch pack in the engaged position. Figure out how to wire it and I think you’ll be good

I think you are right in application,wrong in theory.I think the 236 case has spring loaded detents on the shift shaft.It may very well have a "electric brake" built into the motor,but I doubt it.I may research it later,just not of high importance to me right now,lol.

Why? The factory system works very well,responds quickly.Modify it,and gonna have PCM code problems. 99% of drivers do not need that type of mod. Any serious off road people will change out the transfer case,anyway. I have a 99 astro to build,if I do anything, I will probably put in an older BW awd t case,would suit my needs up here in the mountains.

Personally, I can see the desire for a manual lockup (considering this question has come up on more than one occasion, and I considered it myself)... but whether it is practical, possible, or even necessary is another issue. I guess the idea of having to spin the tires to get the AWD to engage might bother some. Of course that is the beauty of AWD.. that you never have to manually engage it that split second that it is needed. Yes the ultimate is to have the choice of manual and/or automatic engagement, PLUS with hi and lo gear option. Apparently this is done on other vehicles, but not an easy mod on the Astro.

When I was still running my AWD, I actually had my kick panel apart, the wires identified, I temporarily tested it... had the relays and switch ready for install. But I never followed though.. knowing I might unintentionally burn up my encoder motor when I needed it the most. It was that fateful day when I couldn't pull a load off road with my AWD in the soft sand that I realized not only that I wanted manual 4x4 control.. but I also needed 4-LO range as well. Now with the NP233C... my system is completely reliable, fool-proof, and unstoppable, which suits "my" needs.

But it is NO longer an AWD.

This is my NP233C manual 4x4 (in lo-range) upgrade.. pulling 5000lbs slightly uphill in soft sand on a construction site... NO MORE messing around! Just pull the manual 4x4 shifter lever and go! :mrgreen:

But I think we're on the same page.. if you want "manual" operation.. then a manual transfer case is the better way to go!

I can see a use case for it. Mom's lawn, you don't want to wait until it slips a little before going to AWD, but prefer AWD over 4WD.

Makes sense to me. Would be nice if you would flip a switch or a momentary push button.

Hey!!! I might have just thought of a simple ingenious way to manually activate your AWD... simply interrupt one of the driveshaft speed sensors and see if this fools the controller into activating your AWD for you.

I suppose an easy way to test would be to unplug one, and see what happens.

Save the applause! :lol:

Interrupting the signal from the front prop shaft sensor could work without interfering with the ABS system.
