transfer case fluid

I have a 99 trooper with the tod system. I was changing the drivetrain fluids but could not locate the fill or drain plugs for the transfer case. If you have the tod system do you not have the transfer case drain and fill plugs. these are clearly shown on page 8-19 of the manual but sure are not where pictured. I called the service dept but got the standard "bring it in, pay us $". thanks in advance for any help.

look for what will be the largest bolt on the case 24mm socket to remove it
