Engine/Transmission (1998.5 - 2002) Bad Vibration

[ASimpson]

Hey guys this has been an ongoing problem that seems to get worse all the time. I have a bad vibration in my truck rarely if ever notice it while driving down the road. Notice it when you are coming to a stop and all the time you set stopped with your foot on the brake. Here is what is weird to me I have come to a stop sign and its vibrating very loud, loud enough to hear over everything else and hard enough to feel it in the floor and in the shift lever. If i shift up into neutral the noise and vibration go completely away shift back down into drive it comes right back. I have changed things and checked things only thing I can think is maybe transmission mount wore out but it looks ok. Any ideas. Thanks

I would guess either one of the motor mounts or something inside the transmission.

Could be the Flex Plate.

Well guys I'm pretty sure I found it. I was under there looking for all the things that had been mentioned to me when I noticed it looked as if the down pipe was a little close to the frame. About a year ago the brace that goes from the exhaust pipe to the transmission broke off the pipe still felt good and tight so I let it go. Today when I was looking it looked like the down pipe was pretty close to the frame so I started the truck and looked at it. It was even closer but not touching so I figured it was probably binding a little under load I pulled it away from the frame a little took it for a drive and the vibration was gone at least for now. Thanks for all the recomendations as it never hurts to get under there and look at things.
