SYE & 4LO Mode ?

I recently installed a SYE and i cant get the Jeep to shift i 4LO. I am hoping that it is either the shift linkage isnt set or the fact that i didn't cut my shift fork down is the problem.

To be able to identify the problem, i have the following questions.

1. On the 231 Tcase, which position of the actual shifter arm on the Tcase corresponds to what mode ?

2. What mode on the Tcase should the shift fork extend the furthest from the Tcase ? Would i need to cut it on a 93/94 Tcase, i was under the impression it only needed cutting for ones equipped with the Vac Switches ?

3. To adjust the linkage, does the Jeep need to be lifted completely ?

Thanks

you likely need to cut the shift rod

i had to for a 91 and a 96

I removed the tail housing and shaved a bit off the shift fork also re-adjusted the linkages.

It seems to be working at the moment...Hopefully, that was it.

Thanks
