vibration while sitting still
I have recently noticed when I pull up to an intersection and come to a stop I feel a vibration in the truck when I put the shifter into neutral the vibration goes away as soon as I put it back in drive I get this deep noticeable vibration I have not checked any fluids. there anything yet but was wondering if anyone else experienced this before

torque converter.
I would change the transmission fluid ASAP and the filter.
I would also flush out the transmission - if you can afford the cost.
Use Valvoline high mileage Dextron III fluid.
Put in a can of Lucas Stop Slip too.
This may NOT fix it - but will give you a little time before it totally blows out.
Mine has vibration upon acceleration.

Engine mounts are on each side of the engine.
They are rubber and attach the engine to the frame.
They should be good solid rubber and the rubber must not be crushed or deformed.
Transmission mounts do the same thing.
Transmission to frame via rubber.
Rubber still holds the units in place but does not transmit vibration from the
machinery - ie engine or transmission.
When these fail - you may be getting metal engine touching metal frame.
Or metal transmission touching metal frame.
And then the low vibrations.

Hold down the brake pedal.
When you are at the intersection and you go to reverse and give it a little gas - does it go away or get worse?
If you put the brake on again and try to put the gas down just a little in D - does it get better or worse?

If the mounts are broken, you can sometimes see the motor lift quite a bit when doing the aforementioned test with brake applied. Of course, this would be done in your driveway with the hood open.

Putting in reverse is the same vibration..
I am going to check mounts today, but how do I flush the transmission?? is there a plug that is easy to access, and how much fluid goes back into the transmission??
Also I thought the torque converter is separate from the transmission in the bellhousing.. How would flushing the system help it?? does fluid transfer into the converter??
Thanks, and the vibration is getting significantly worse
