Engine and Transmission Problems

[ghostdrifter]

I read your posts and you sound like you know a bit about transmissions. So here goes. I am new to his forum so bear with me. Here is my problem. Keep in mind I am not a mechanic. I have a 2002 Ford F250 diesel with 7.3 l engine.

Recently, my batteries went bad so I replaced them. I also replace the fuel filter. The truck runs rough until it is warm then it runs smoother. The real problem is this. All of a sudden the truck will not move, when on a slight grade, when I put it into drive. When I press the fuel pedal, the engine seems like it looses power, and rpm's are very low, like it is lugged down. When I put it into park, the engine seems to have power because the rpm's rise to just below the red line mark. Also, the overdrive light on the shift lever blinks. I read on this forum somewhere that this might be a computer problem. Someone told me to disconnect the batteries and it would reset computer.

I did this this morning, and the truck seemed to run better, and the overdrive light stopped blinking. Still no movement. Remember turck in on slight grade. I next want to check the trasmission fluid; but, because of grade, truck not level, this is not an option.

So, I'm setting in the truck, completely miffed, with it in drive with accelerator depressed. Truck seems like it wants to move, but nothing. Then all of a sudden the truck starts to move slowly, but it moves. I manage to get it to a level spot so I can check the transmission fluid. I check the fluid while engine is on, and the level is good. Also, the fluid is bright red, which I have been informed on this site that it means the transmission is propbably ok.
