Dodge T-case question

[plyr2k]

I just got a 1994 dodge 2500 with a cummins, and an automatic. The T-case is bunk. The lever, and visor, in the truck designates full forward on the shifter is 2wd, 4-hi, neutral, then 4-lo. The case kinda worked, made funny noises and skipped and such, but bit it today. The shifter patern when it worked was different from the shifter and visor. It was full forward was 4-hi,
2wd, neutral, then 4-lo. My question is what kind of case do i have? And what kind of case am i supposed to have?

try it in neutral or with the engine off in N for 4 lo thats the only way mine go in and stay .

Tested and tried that. The front end locks in, but not the t-case. its been changed, and made horrible noises before its demise. Im just trying to find out what i should have. The underlying cause just maybe to light of t-case.
