transmission woes, I think?

I have a 1997 Land Rover Discovery SD with 69,534 miles on it. I just got it about a month ago. I was driving home and I was going up a hill and the vehicle started to rumble a little as the vehicle began to slow down. I pressed the gas a little more and the car was bucking lightly. The RPM guauge was revving really high, so I pulled over, tried to put in 4 wheel drive to help it along and nothing. I shut the vehicle off for about 1-2 minutes. Started it back up again and put it in 'drive' and it ran fine for about 2 miles and started to slow down again. I stopped for about a minute or so, started the vehicle again and it ran for another mile or so. I repeated this til I got home.
I am hoping that the transmission is still good and this is a minor problem. My gut feeling is that the torque converter has gone bad. Big Money!

I need some input on this, please!

Thanks.

My first thought was fuel!

What does the fuel have to do with the transmission slipping, OutbackJack?

sounds like the torque converter or poss the bands in the auto box
