Clunking feeling... what is going on

[JPerkMr954]

Im not sure exactly whats going on with my 2005 yukon... nothing major but i want an idea what it is....

Sometimes at a redlight, when pressing the brake, and i release i hear something like "clunk" or release.. not like a tranny slipping or something... just a sound and a slight feeling.
I have felt one time since owning my truck pressing the gass and a slight momentary time when the engine will rev and the tranny not grab immediate... what do you think this is? A tranny fluid issue or is there something i need to be preparing to go bad?

You might want to have your U-joints checked out.

Mine started doing this about 2 months ago so I took it to someone and they did not know what it was doing so he changed the fluid and filter went away for a while and then started again about 2 weeks ago and the tranny went friday. So kinda sounds like tranny issues to me

Clunking

I havea 2005 Tahoe and it does a similar sound from either stop to 1st or 2nd or when i slow down to take a turn then start to speed up. Not sure if Tranny problem or something in the shaft. Dropping the tranny will cost me around $900, i only hope its not that.
