Sometimes when you do a complete plan with a TRANS and STAR, for some reason the FMC doesn't enter the speed and altitude constraints to the plan. The solution:

Alright, maybe my explanation was a bit long...I'll shorten it up a bit  ;) Enter your entire route including SID and STAR and remove any discontinuities. Press LEGS to go to your 'ACT RTE 1 LEGS' page. Select any waypoint / VOR and place into the scratch pad. Place the scratchpad contents into any LSK1 - LSK-6 location. Do NOT press the execute button. This will cause the FMC to go into 'MOD RTE1 LEGS' and force recalculations. Wait a few seconds then press 'Erase' to cancel. T/D should now be displayed!

I know this is silly to ask. But....You are changing the Altitude on the MCP (autopilot) so that the plane will descend once it reaches the T/D? Mind you, the FMC should warn you to reset the altitude on the MCP before you reach T/D. I'm just covering the obvious, because even I have forgotten to do that on some occasions! Did I really just admit that? ::)

Hope this helps.
