Transmission problem?
I need help...
I'm not sure if this is a transmission problem but I'm starting here. A while back, I was driving at 55, and my truck started vibrating hard (like I was on a rough road, but I was on a highway). The vibrating seemed to last for about a half mile and then stopped. I could also feel the vibration in the steering wheel but it was not as strong as I was feeling inside the cab (there was no shimmy in the steering wheel, so I have to rule out a loose front end). Recently, I have felt the vibration at lower speeds (almost like I was lightly tapping the brake pedal, which I was not). I've been under the truck and looked at the driveshaft, gave it a good shaking and it was very firm.
I've also had problems with the transmission shifting hard. From a slow speed, pressing on the gas pedal and the transmission would downshift hard (no audible sound, though I could feel the transmission shifting hard). When I was pressing on the pedal, I was pressing moderately, not like when trying to pass another vehicle.
My truck is a F150, 1999, 2WD & a V6.
I know this may sound vague, but I would appreciate any help.

Exactly the same problem I am experiencing. I just worded it differently. See my thread titled "harsh shifting" under Transmissions.
I have yet to have anyone provide a reply.
Hey, Ford mechanics, give us some help.

Dogbite;
Check your left rear parking brake cable. It is a short cable only about 3 feet long. They wear out and don't completely retract when you release your parking brake, leaving the rear brake rubbing. It gets worse in cold weather. After you drive for a while, the brake drum heats up, warps and starts to vibrate. The vibration gradually releases the parking brake cable and it goes away. I had this happen to me and it took half a winter to figure it out. I hope for your sake that that is the problem because it's a lot cheaper than a transmission repair. Good luck, GlennMc.
