Accessing higher security level from higher security level

I'm a newbie and and setting up a pix firewall and i need to access higher security level from a lower security level. Ideally just need to be able use terminal services. This is what the configuration is. I need to user terminal services from tmx-dmz to get access to singlemom. This is just the relevant stuff below for this network

nameif ethernet0 outside security0 nameif ethernet1 singlemom security98 nameif ethernet2 failover security97 nameif ethernet3 intdmz security80 nameif ethernet4 dmz1 security40 nameif ethernet5 tmx-dmz security90
