NP233 electric shift to manual shift swap

Post by LiftedAWDAstro »

I want/need a true transfer case with low range so I decided to go with a NP233. Initially I wanted to use all the electronics and wire it in all proper like. After messing with and trying to figure out the wiring as none of the diagrams I found were the same, I decided to convert to manual shift. The reason I went with a 233 instead of a 231 is that all the 231's I have seen pics of have a yoke on the front output and with the 233, the stock drive shafts will fit with no mods.

Pulled the shift motor/encoder off...

Just for future reference on installing a low range switch for the PCM.

Started making the shifter pivot bushing assembly. I also ordered a cable and a couple rod end clevises for the cable. Going with cable shifted just like I did the SPB. It worked well and makes for only a single hole drilled through the floor.

This shoulder bolt will be bolted to the seat frame and have a shifter handle and cable linkage arm welded to it.

You can always use a 231 later....... they are better for doubling anyways :whistle:


Is this the start of the monster that I'm sure next year at some point I will see on the front of PBB and a vid on the powerblock?

No plans for a doubler or for a SAS or any type of wheeling. I am hoping to lift it next spring but we'll see. My money is better spent these days on paying down our debt.

Looks good, and the bonus is you probably can sell the module for the cost of the TC!

Gotta say I was disappointed you didn't go with the 242, but if a 233 would have been a no driveline mod to my '98 it would have been hard to resist.

The 242 would have been nice but I didn't want to spend the cash on the adapter and then modify the drive shafts. Hopefully I can build the rest of the cable mount and the shifter tomorrow.

Yeah, yeah...I know the van is a mess! :D Been raining here for a few weeks so there is a lot of dirt and mud in the van. Next nice day it'll at least get vacuumed out.

That is a great design. I plan to copy your idea for my 2003 AWD Astro next summer.

Thanks for great photos.

Go ahead and copy it! :supz: The hardest part (for me) is going to be pulling up the carpet so I can drill through the floor and mount the cable and then get the carpet back down and looking good.

you may be able to save yourself a lot of trouble by just mounting through the carpet and use a cover plate. Slightly different application in the photo, but I screwed the mount under the floor.I really didn't want to pull up the carpet!

I did that with the SPB and it worked good. I may do the same this time as the trim moulding screws are pretty rusty from salt.
