Putting my NP205 back together and need sourcing on two parts and Identification on a third (and it's sourcing)

1st photo is for two switches on the NP205. One on the right looks to be the 4wd switch. Where can a new one be found?

One on the left is magnetic bit I can't figure out what it is. Where can a new one be found?

2nd & 3rd photo is the output flange/yolk to the front driveshaft. Any sourcing on that and a new output shaft bolt? The surface where the seal runs is grooved. Would like to find a new one...

I checked ORD but couldn't find these parts. Any sources out there??

2nd is a VSS sensor . Its for 90 or 91 only in gm speedo sensor .

Get a speedi-sleave to fit over the grooved yoke . Cheepest is rockauto for them .

Good deal. I won't need the VSS so I can plug that hole. I'd rather get a new front yolk/flange. Sleeve is last resort. Going larger driveshaft so may need larger yolk anyways.

Any sources for the 4wd sensor?

You wana deal on the vss parts ? If so pm me please .
 
Only for the 4l80e programming.
Your road speed would be from the t case.
Since high range is the same as trans output shaft the 4l80e could be used. Low range might confuse the computer.
 
The 4x4 switch for 20 bucks is not for the 205. The 205 switch is long discontinued and not reproduced.

I may not be remembering correctly, but isn't this why guys use the one in the T-case and omit the one in the rear of the transmission?
I seem to remember that my '01 has a blank plug in the rear spot.

But I also seem to remember that the trans controller needs to have an input for 4wd to change the map as well.

@mrk5 can you advise?
 
If you want the transmission to shift properly in low range, you should use the speed sensor in the tcase output. You could use the 4l80 output speed sensor, but it'll never, or nearly never shift out of 1st gear when you're in low range. Sometimes I forget to change the transfer case range on the stand alone controller and I quickly figure it out when the engine revs out and never shifts out of first.

Most after market trans controllers will ignore the input speed sensor, or can be programmed to ignore it. The US Shirt Quick 4 in the crew cab can be programmed to use or ignore the input speed sensor. The Edelbrock trans controller in my C10 doesn't utilize the input speed sensor at all.

Likewise the US Shift controller will change transmission behavior in 4wd, but not necessarily the shifting behavior. There's a lot of changes you can make to the torque converter clutch behavior in 4wd, but you have to manually tell it you're in 4wd. Now the US Shift will allow you to use the transmission output and it can compensate for being in low range by what you program into for the low range gear.

The Edelbrock trans controller doesn't care about 4wd.

Was planning on using a AutoMeter Spedo based on GPS....

I have an Edelbrock controller that should mate nicely with the Edelbrock Pro-Flo system
