They stated at the dealer it would not swap I would assume cause of the transfer cases... The 1999 has the 4x4 part time, neutral, and 4 Lo system... The 2001 has the selectable 2hi, 4x4 part time, 4x4 full time, Neutral, and 4 Lo... But it was stated that they are the same trnasmission model wise... So is it just the transfer case I guess?

The Transfer case is the same and the transmission is the same. the difference is the electronics in the transmission. In 2000, the electronics changed, the governor pressure sensor/solenoid are wired differently. What will happen if you install the pre 2000 in a post 2000 car it the PCM will struggle to operate the transmission. You will have R, 1st, 2nd, and 3rd operate normally, however, OD/4th may not operate at all, or will only operate after the transmission has warmed up. A solution would be use the transmission but swap the electronic components, if they have failed in the old box; use the housing and replace the OD clutch solenoid and Gov Pres/Sens.
