Need some advice

Over the past couple of days, my Taco has been acting odd. Anytime in gears 2-5 that it is below 2,000 Rpm, it shakes the truck. When I hit the gas, it shakes violently. Once it's above 2,000, it's usually fine. It can be at 1900 rpm and it still does it. This is not my first manual transmission vehicle, but the first time I've ever experienced this. Suggestions?

 

Check your 3 motor/tranny mounts.

 

At speeds appropriate for the gear?

So you're not lugging the motor, right?

 

Correct. I know what it is like when you're just in too high of a gear. This is different. This is like extremely violent shaking of the entire truck. I will see if it's possible to take a video of it

A good place to start is the drive shaft. Might be the U joints going bad??..

 

It is just odd. It idles nice and smooth. It doesn't do this in neutral. No check engine light. And if you push the gas pedal while it's happening, it shakes/jerks the whole truck bad enough to give you whiplash it runs perfect after it gets over 2000 rpm. I could just downshift to always stay over, but I want to fix it and not just ignore the issue
