push button to manual floor shift transfer case conversion 1998 Chevy k1500

- converting electric push button 4x4 to a manual floor shifter without changing the transfer case or doing any kind of wiring, all mechanical.
The reason for doing this is because the electric motor on the transfer case quit working and the 4x4 switch in the cab would not always work.
It was cheaper to convert the truck with components that shouldn't ever go bad or wear out than to just replace the overpriced chinese electrical components.
This truck is a 98 k1500 with a 5.7, 4L60E, and an Np243c t-case. it is also a short cab.
other information: the front electric axle actuator does not work if the electric motor on the t-case is not plugged in, (at least ours did not seem to) this is why we also needed to convert the front axle actuator to a manual setup. ( the posi-lock kit)
The scrap plate that holds the blue shift lever from falling off the transfer case is just a hair away from touching the peg that sticks out of the transfer case, (just used some washers)
This whole project cost about $180, we paid $30 for the stock chevy shift linkage at a junkyard and used hardware and some bar stock we had laying around to create the linkage, the posi-lock kit was about $150 off summit racing. The cost of the electric motor and the 4x4 dash switch is around 180-210 depending on where you get them, yes it would have been easier to just replace those components but the manual floor shifter should outlast the truck.
does anyone else put mashed potatoes on garlic bread
Great video!!! Cured my anxiety attacks dealing with the electronic transfer case!! Thank you guys!!
Very good video gentlemen ! You totally explained as well as showed every step necessary ! Hats off to you two, it will help all persons having trouble with their 4x4s and not wanting to get rid of their trucks ! Again good job !
Nice! The electric switch on mine keeps throwing codes. Will definitely try this. Awesome art too.
Nice video! I'm looking to figure out how to manual swap everything on my auto 99 Tahoe and this helps a lot. Seems like it would be easiest for me to buy a manual parts truck and just switch everything over.
Great fricken job guys... saving this video for my next project
Damn thank you guys I’m building an 92 xj using a 4x4 5.3 using one ton axels with hub locks
They got off topic pretty quick with the posi 😂
Sweet vid great for ideas. Might be doing this on a 96 jimmy.
😀 finally found what I'm looking for great video
Excellent 👍 thanks
I put vise grips and rope on mine long ago.. 😂
Interesting.
At about the 7:28 mark it shows the linkage underneath the truck and you say the plate bolted into two of the encoder motor holes is holding the shift arm onto the transfer case output shaft. Is the plate just snugged up against the output shaft using washers for the correct spacing?
I have a transfer case not engaging with the encoder motor for some reason, yet I get no blinking light 'error' on the 4x4 push buttons. I took the encoder motor off and noticed that I could manually lock in the transfer case with a wrench. I almost bought the Posilock but instead rigged up a carburetor cable under the hood that I lock in whenever I think I might need it. My '98 Blazer is at the point where I'm going to put a lever on because it's done nothing but let me down when I really needed 4x4. The engineers that came up with that terribad combination vacuum/electrical 4x4 system should be court martialed and shot. (I'm sure it made GM tons of $ from clueless fairer sex customers which is probably why that system was put in to begin with.)
No mash potatoes on my garlic bread, thank you.
I believe that neutral is for flat towing a vehicle.
nah m8 it definitely makes grinding sounds
Do you sell a kit ? 2000gmc sierra 5.3 stock trans great video !
Anyone know we're to get a billet tranfer case lever? Can't find one Anywhere
Will this work for 2003 chevy suburban
Would it be possible to use a fused relay to engage the front actuator?
@@things7141 thanks! Gives me a few ideas.
Mine the transfer case got smashed by whoever owned it before, so I might as well put in a np261 and put in a lever. What I'm wondering though is the screen on the dash says "service 4wd" every few seconds, do you know how to get rid of that? Thanks
Either a sensor or an actuator is malfunctioning somewhere. To try and reset the light, there is a way that you can jump two of the contacts on the OBD port and perform a series of key cycles. This will clear out the memory in the transfer case control module. You can find other videos explaining this procedure for different vehicles.
Hey man I want to do the same thing I have a 2002 Silverado with a 4l60e transmission with a np246 push button 4wd autotrac junk and I done burnt out the clutch pack in the tcase that's why my 4wd doesn't work I want to swap in a manual shift tcase that doesn't use clutch packs what tcase do I need that will bolt right up I'd like to have a gear driven transfer case but a chain driven tcase will do ....by the way I don't know the spine count on my current tcase....as for the shift linkage I can fab up something that will work
I do not know off the top of my head what specific transfer cases will bolt up or what the spline count is. If you are wanting to swap the case anyway, just take it off and count the splines.
I got the np246 auto trak case. I hate the push button and want to do exactly what you did and switch it to the manual. What trans case do I need to pic up? I also have the posi lok for my k2500 that iam literally installing now. Great video and job guys.
Thank you. If you're looking for an already manual option, the np241 will most likely work as long as things still bolt together however there are stronger options. Just search for things that will bolt up to your transmission/trans-transfer case adapter. There are quite a few options out there depending on whether you want a chain-driven or gear-driven transfer case. In our situation, we did not want to swap out the transfer case (because poor) which is why we created a linkage to replace the electronic actuators.
@@alecschauer9902 Now it makes more sense. I thought you converted to the 241.
You don't have any issues with the transmission shifting at all? Since the computer doesn't have the position sensor to talk to?
No issues, over 3 years later and it works perfectly.
The truck doesn’t seem to know or care about having all that stuff unplugged
Excuse me, how to get that shifter and the other pieces?
Great job.
Thank you
Got em out of a similar truck that had an np241 with a manual shifter.
I’m looking to manual swap my 8.1L Suburban, which has full electronic 4WD. I know I’ll have to convert to a floor-shift t-case, so would this still apply? And if so, how could I wire the t-case to still activate the front actuator? I believe it’s a NV246 t-case.
Things well that answers my question... what was the estimated time y’all worked on it ?
Things thanks cuz this is my daily... I didn’t want to be out for a week or so... will update later...
You could also swap in a one piece passenger side shaft and tube from an AWD truck. lightly worse fuel economy but who cares.
How did you seal the hole in the floor? Did you use any sort of boot?
The shifter assembly is a stock factory part. it seals the same way the factory installed ones do. it just has a rubber gasket that goes on one side and is squeezed between it and the floor. Water could still come in the slot the handle slides through just like every other truck that has one but at that point water would be coming in the doors
In this case we did not use any kind of seal because I did not care. The assembly usually has some sort of seal, though, as well as the brush thing on the OEM cover plate depicted at 9:45.
Can u do this on and awd? My 2001 bravada stays on 2wd and wont engage AWD
Without knowing the shift pattern inside the transfer case, I can't say whether or not it will work.
The neutral or selector position that doesn't do anything that you speak of that's the Auto 4 wheel
Sir I assure you that the NP243C transfer case that is in this here truck does not have a 4-Auto position. That was an option on some later vehicles such as my 2001 Blazer, but the original electronic push-buttons that came in this 1998 K1500 only had 2-HI, 4-HI, and 4-LO. I could be wrong, but the majority of transfer cases that I have knowledge of usually have some sort of neutral position between the HI and LOW range for safety reasons. Because this T-case was never meant to be used with a manual shift lever, this "neutral" position simply felt a little hinky to me to the point where I would not be comfortable using it as a means of putting the vehicle in a neutral state.
Also.... the grindy noises say no
I'm having trouble learning how to use my manual tcase on my 1999 nbs 2500 silverado I follow the steps from the instruction manual but end up grinding any tips?
The transfer case or the shift linkage is probably messed up.
the blank space would be neutral right
It is neutral, but it isn't normal to leave it in there...just pass thru it to 4wd low.
Why is the shifter in such an odd position?
He wanted it far up, tucked out of the way so it wouldn’t ever get kicked or knocked by someone sitting in the middle while driving.
Just a heads up on doing yourself videos. Only let one person talk in the video. On this video when the second person starts talking it makes the first person sound like he doesn't know as much as the second person. It also confusing.
How can you change the manual to buttons ?
So you're wanting to swap from one that has a manual transfer case to one that is button-actuated?
step one: get an electrical engineering degree
step two: now you can afford to buy a different truck
Why would you go from I know this works to I hope it works

Thermal ?
@@things7141 Ok, never heard of that on these so I need to look into that gas expansion type actuator. Do you have a part number ? I have done several S10's and own an '89 that were all vacuum operated. And one that was electric. Agreed they are all poorly designed, too many points of failure.
@@things7141 I never heard of a thermal actuator on these. Always thought a thermal expander was on HVAC, not on front axles, and called a Capillary Bulb.I already converted mine, and others. Missed out on a Posilok thing a year ago for $40, new. So then made my own pushpull cable. Have a floor shift already for transfer case.
you don t need to lock the front with a cable /when you manually put it in 4x4 /the vac sensor on transfer case wiil engage front diff
Nope, wrong. this truck was equipped with an electric solenoid on the front axle housing that worked in conjunction with an electric servo on the transfer case. Only when the servo on the transfer case had completed its shift, would A computer (The 4wd controll module) tell the solenoid on the front axle housing to engage. Because we removed the servo entirely, the computer would never see a completed shift and there for never tell the solenoid to actuate. The cable pull is manually and physically moving parts in the front housing. vacuum has nothing to do with the 4x4 on this 98 k1500. Not a thing.
@@goreerh So if i swap my push button 243 with a manual 241, I'll have to use a cable to engage the 4wd along with the manual shifter? or can i just use the manual shifter?
If your gonna swap your transfer case for a 241. Then just find a truck that has a manual linkage for a 241 and take all the electronics that control the front axle actuation. Theoretically you could integrate those into your truck and have a shifter that works like factory. If you don’t want to deal with all that Jazz just use the posi lock kit, it make shifting into 4x4 more of a process but it removes all the electronics that like to go bad.
DOOOODGE!!!
Audio is bad.
