Thought one of the tranny guys would jump in.
By no forward gears, I assume you have reverse? If no reverse either, transfer case in nuetral?
The forward clutch operates with all forward gears. If it fails it could cause your problem. Also not enough fluid/pressure applying the forward clutch pack would cause your problem (blown valve body gasket).
Why did you change the fluid? Was the fluid burnt? Any debris in the pan?
6 Month old trans, any warranty left?
Have not done a lot of AT work. The ones I've seen have burnt fluid and debris in the pan and are due for an overhaul.
