Transmission problem??

[brenglen]

I don't know if its a transmission problem or what however I have attached a video on what has been happening when I put my car in Drive. It sounds like something is shaking underneath my car. However when I put it into park or any other shift i don't hear it. Is my transmission going out? I've never flushed or changed my transmission fluid (its at 135k miles). I am very nervous on doing anything with my trans, that is why I didn't change my trans fluid.

In the video, I start off in drive then put in park then i tried Neutral and switched back to drive.

Sounds like the exhaust pipe is contacting something when you put it in gear, check the rubber isolators at all the hanger locations. Also inspect your motor mounts.

And that your downpipe isn't hitting the swaybar.

blown motor mounts? have some one shift it while you watch it from underneath. follow the sound till you see it hitting.

also pop your hood, then get in the car, shift it fro P to R to D, watch the engine for movement, if its jumping back and fourth when shifted the mounts are bad for sure.

I replaced one of the motor mounts last year, I guess the other motor mound is bad because I did see some movement back and forth when shifting from D to R. I also feel the vibration from the drivers floor. I'll get it checked out on monday. Thanks guys.
