I have own a 2005 Titan SE 2WD for many years. Decided to trade up to a 2007 Titan LE 4x4 last Monday, both Crew Cab. Of course, after I brought it I noticed that when I accelerate slowly in this Titan, I can feel a deep vibration from the engine/transmission, which I never had with me SE. The vibration is not in the steering wheel. My passenger can fell it too. This only occurred after I have already come up to speed, let off the gas pedal to slow down and slowly accelerate again. Not sure if it happen at all speed, but I know it had happened to me at 40+ to as high as 70+ MPH so I can't believe it is because it was in "between" gear. If I was to step in the gas "hard" to accelerate, I don't feel it or there is no vibration. Also, I don't feel any vibration from accelerating from a dead stop, slowly or quickly.

I have read some blogs that said this is common/"normal" on vehicle with a CVT. But I have also saw a blog in this forum that a Titan isn't equiped with a CVT.

Any idea beside don't accelerate slowly?

Not a cvt transmission. Vibration can be anything. Tires, u joints, and even a tranny mount can cause vibration. And only doing it when accelerating makes me think tranny mount. They can cause vibration when the rubber wears out.

Sorry don't mean to pirate this. But would a bad trans mount also cause vibration while in drive and the brake applied, like sitting at a light after driving for a little bit.

Tranny mount or motor mounts can cause vibration when in gear and not moving. Motor mounts cause more noticeable vibration when idling than tranny mounts that I have noticed. Put it in neutral next time and see if the vibration goes away

I will take a look at the tranny mount this weekend. Supposedly, it a "new" transmission on the truck when I brought it (don't know what's wrong with the old one). The dealership said Web Transmission have a 2 yrs or 24K mile warranty on it so I have the warranty if something does go wrong with the transmission. You would think when they installed the new tranny, they would have replaced the mount if it was needed. Nonetheless, I will take a look at it this weekend. Thanks.

I always thought it was a truck thing. Ive driven trucks from the tundra- ram1500 they all got a slight vibration from the floor board when you accelerate
