What is the rumble from?

On the highway at about 60MPH with the tranny in Overdrive, when I go to accelerate a little bit, it downshifts and gives me about a 2 second rumble. I know the downshift is normal but I'm concerned with the rumble. I had a '96 Explorer that did the same thing and I drove it for 5 years that way, but I'm hauling a lot heavier loads with this than I did with the Explorer and I don't want to tear up anything. Any ideas as to what could be going on here? Thanks.

Either the shift solenoid or the torque converter clutch solenoid is bad or you may need a rebiuld.
The first thing to do is have the trouble codes pulled to see if it is a solenoid.
Any Auto Zone or Advance Auto will do this for free.

Ok, so I took your advice and went down to Advance and had them run the ODB2 scan on it. Unfortunately they're telling me that the plug on the truck is messed up and they cant get it to reed. I guess I'm going to just keep my weight down on it. I cant really afford to rebuild the tranny or guess around on solenoids. Thanks for the advice though.

More than likely if the rumbling is easily felt, there is some mechanical damage to either bearings or bushings.
You might try changing the fluid and filter, if applicable, and try a bottle of Lucas Bros. Trans Fix.
They make some good products. I am not saying this will fix your problem, but it will at least keep it lubricated well enough to get as much time out of the transmission before rebuilding it is necassary. The problem will prograssively get worse, more than likely, before it completley fails and thus leaving you stranded. If you drive it hard or tow, this is not going to be true and you can never tell for sure when something is going to leave you stuck.
But palnning ahead some will at least save you money on towing and changing the fluid will buy you some time to plan what you are going to do.
I am sorry the reader port is messed up. You might look into the pins or see about getting another one from salvage yard as the information you can get from reading trouble codes is very helpful.
Let me know how things turn out.
If you need any other help, there is a great team of techs here and we are always ready and willing to help.
