Sounds like it could also be fuel related. Give us more information.

You said the engine felt boggy. Does the engine feel it's loosing power?
If the transmission is the problem the engine should still have plenty of power and not feel "boggy".

Here's another thought for you. Check the fuel pressure. May not be a bad idea to replace the fuel filter.
You may want to try using SEAFOAM. There is a thread on this site how to apply Seafoam directly to your intake though the upper pcv valve hose.

Replacing the pcv valve night be a good idea also.
What engine do you have? Are the plugs and wires good? These little things can make a big difference.
Do you have a check engine light on?

Your best bet is to make a distinction between whether it is the engine or the tranny that is causing the feeling you are describing.
