Default Ls3 4l60e in a 2000 tj vss question

All you experts out there I am doing a hybred 231c 231j transfercase and I read that it is possible to put a reluctor ring and vss in the stock adapter between the trans and transfercase I have a Bridgeport so this will be easy to do. What I am wondering about is low lock and the transmission and speedo not working correctly because of the gear reduction. Am I going in the right direction with this trying not to buy all new gauges.

Does it really matter your speed in Low range?

I don't even have a speedo in my Jeep but use a GPS app on my phone when I want one.

If you put a GM 40 tooth reluctor and VSS in the 4l60e tailhousing, you'll be fine. No need for a 4wd switch or anything. Advance adapters sells a clamp-on 40t reluctor that is the proper diameter to fit on the 4l60e tailshaft. Make sure you set the proper air gap on your VSS to reluctor. If i recall (might be wrong) mine was set at 0.005".

use the 231c front half, with a 5 bolt adapter on the trans. Use the 231J back half, with 231j mainshaft. Keep the jeep VSS on the transfer case output shaft as it normally would be and your speedo will work just fine.

I have this setup in my TJ currently and while its alright, it could be better. Mines been together for 20-25k miles and i haven't had an issue yet with the adapter (knock on wood.) If you can get a clocking ring and clock the transfer case up a bit, things would be much better. My rear shaft is at a hell of an angle with an SYE on it because my trans mount has to be up high to clear the front output of the case.

I remember you wanted to take a look at mine. Sorry I never called you back, had a bunch of stuff going on. If you still want to look at it, let me know.
