Thanks Jared - This is the second time I've changed the ATF in this truck. I was trying to get all of my vehicles on the same schedule. I probably had another 20k on the interval - should have left it alone.
I agree the trans flush sounds like my best bet at this point.

a power flush at 187k will definitively finish the tranny IMHO.
have you checked the tranny for codes?
is it possible the transfer case is in neutral?
is the o-ring on the filter correctly?
just thinking of things that could have been over looked

drowssap - sorry, drill weekend so just getting back now. O-rings are good on both sides of the pick up tube. Transfer case is in 4 high and no tranny codes show up - at least not on my code reader. I'm not sure if it's capable of reading them though. It's a generic code reader OBDII compliant. Thanks for the ideas though!

Don't flush it. FORCE fluid in there. It took my upwards of 10 quarts to finish my brothers truck, his was a pita, while mine was super easy. I have changed my fluid twice also and my trucks transmission shifts flawlessly.
Good Luck,
Dane

Nope. Try to find a fitting that will go in the fill hole semi-snug, or just use your fingers to hold it in there and just keep pumping it, even if it's coming out. Then do it again, then run through the gears, then do it again... it took me quite a while to get my brothers truck moving again. Your pump probably just lost its prime.
I'm thinking you cant blow a trans by just draining the fluid, well, its hard to believe at least... I think there just isn't enough in there.

If you removed the fill plug with the engine off and nothing came out then it sounds like you were low on fluid to begin with and that may have caused some damage. Also, When you changed out the fluid and filter it may have dislodged some debris that clogged something up. This is why it is only recommended to change your transmission filter once in your transmissions life time and I think it is around 35,000 miles (I may be wrong).
I think your best shot at fixing the problem without a new transmission would be to have the truck towed to a shop and have them hookup a trans flush machine to it. If you do have a blockage then the flush machine might be able to suck it out.
I have used one of these before and you hook up 2 clear tubes to the trans and you can watch all the dirty old fluid flowing through the tubes and slowly changing to nice clear pink color. It is actually really cool to watch it work on really dirty fluid.

I change my trans fluid every year. I actually change every fluid every year other than oil and anti freeze. Oil every 3000 religiously, AF every 3 years or when I notice gunk in it.
The trans has moving parts, just like the rears and the engine. the fluid doesn't cause damage its what's in the fluid. the cleaner you keep your fluid, the less damage the crud, metal particles can do.
We have 167,xxx on our rover...
I had a van that went 336,xxx...head gasket went and I junked it.
I always shoot for 300,000 on every vehicle. I do all maintenance myself.
Hardly no one flushes their cooler. Even quality trans shops skip the cooler maintenance. I like to take the lines off, spray brake kleen in there and make sure there's good flow.
In many cars, trucks, the A/T fluid is cooled in the radiator, when the cooling system is inefficient so is the trans. Something to think about.

shanechevelle - thanks for the insight. The rad on my Disco is pretty brand new <8 months old and seems to be working pretty well. This was the second time I changed the ATF in this vehicle, but I am not the original owner so can't vouch for what was done to it in its lifetime.

@Dane! - I agree. Again, there was no noise, no smell of burned fluid, no screeching halt, nothing - just an inability to shift gears. What little I know of transmissions tells me there is no hydraulic pressure - and hopefully that is due to too little fluid and not a failed pump. I bought a rubber stopper (for the fill hole) and drilled it out to the diameter of the hose of my hand pump. I'm going to try your forcing idea tonight and see what happens.
